It is often a sign of an architectural approach’s maturity that in addition to the emergence of well established principles and practices, that anti-patterns also begin to be identified and classified. In this talk Daniel will introduce the 2016 edition of the seven deadly sins that if left unchecked could easily ruin your next microservices project... This talk will take a tour of some of the nastiest anti-patterns in microservices, giving you the tools to not only avoid but also slay these demons before they tie up your project in their own special brand of hell.
Topics covered include:
Envy - introducing inappropriate intimacy within services by creating a shared domain model, and how many teams deploy and use data stores incorrectly;
Wrath - failing to deal with the inevitable bad things that occur within a distributed system;
Sloth - ignoring the importance of NFRs; and
Lust - embracing the latest and greatest technology without evaluating the impact incurred by these choices.
microXchg 2017: "Microservices: The People and Organisational Impact"Daniel Bryant
Microservices are where it's at. Everything is easier to manage when it's micro, right? Micro code bases (less than 10 LOC), micro containers (less than 10Mb), and micro teams (less than one person???). 'Micro' things may appear to be easier to manage, but there is always a macro context, and working with people and teams is no exception. This talk presents some of the challenges the OpenCredo team have seen when implementing microservices within a range of organisations, and we'll suggest tricks and techniques to help you manage your 'micro' teams and the 'macro' level.
Topics covered include: empathy - because understanding others is at the heart of everything you do; leadership - advice on creating shared understanding, conveying strategy, and developing your team; organisational structure - from Zappos' holocracy to MegaOrg's strict hierarchy, from Spotify's squads, chapters and guilds, to BigCorp's command and control. There is a management style for everybody; and more
OReilly SACON 2016 "A Practical Guide for Continuous Delivery with Containers"Daniel Bryant
Is continuous delivery mainstream? We would all like to think so, but as William Gibson reminds us, “The future is already here—it’s just not evenly distributed.” The large (unicorn) companies have been talking about deploying containerized applications for some time, but the processes, techniques, and technologies involved are not always clear when looking in from the outside. This can make it difficult to emulate their success.
Based on his experience building several Docker-based applications that were deployed to a range of orchestration and scheduling platforms, Daniel Bryant demonstrates how to create a scalable build pipeline that takes a series of Java applications, containerizes them, and deploys them to Docker Swarm.
Example code will be available to download via GitHub, and the examples can be executed locally via Vagrant.
LJC 2015 "The Crafty Consultants Guide to DevOps"Daniel Bryant
Come along and learn how the Crafty Consultant makes his money by consulting craftily in DevOps. We'll see how silos can be broken down by introducing more independent and isolated team, how only idiots automate everything, and why monitoring only provides actionable insight that simply confuses your clients...
...and then we'll look at the real world implementation of DevOps :-) The primary aims of this talk are to introduce the concepts behind the DevOps movement, and we'll do this by debunking all of the Crafty Consultant's advice. We'll cover the drivers of breaking down silos (in business and in tech), the benefits of automation (especially with provisioning and configuring infrastructure), and the power that monitoring provides (particularly when deploying to the cloud, or implementing a microservice architecture).
LJCConf 2013 "Chuck Norris Doesn't Need DevOps"Daniel Bryant
We all hear the term "DevOps" being thrown around on a daily basis, but what does it actually mean? With a little help from everyone's favourite 80's action hero, we'll undergo a whistle-stop tour of the philosophy, culture and tooling behind this buzzword, specifically aimed at Java Developers. We'll also look at a real-world case study from Instant Access Technologies Ltd, and explore the key role that DevOps has played during a successful upgrade of the epoints customer loyalty platform to support increasing traffic. The core discussion will focus on the challenges encountered as we moved from a monolithic app deployed into a data centre on a 'big bang' schedule, to a platform of loosely-coupled components, all being continuously deployed into the Cloud.

The technology changes required when implementing a microservice-based application are only one part of the equation. The business and organisation will also most likely have to fundamentally change. In an ideal world, this shouldn’t be a problem - what with the rise of agile, lean and DevOps - but this is not always the situation I encounter in my consulting travels. I would like to share some stories of successful (and not so successful) strategies and tactics I have used over the past four years when introducing service-oriented architecture into organisations.
Join me for a whistle-stop tour of the business and people challenges that I have experienced first hand when implementing a greenfield microservice project, and also breaking down a monolith. We’ll look at ‘divided companies’ vs ‘connected companies’, determine the actual impact of conway's law, briefly touch on the lean startup/enterprise mindset, dive into change management without the management double-speak, and look at the lightweight processes needed to ensure the technical success of a microservices implementation.

J1 2015 "Thinking Fast and Slow with Software Development"Daniel Bryant
In the international bestseller Thinking, Fast and Slow, Daniel Kahneman explains how we, as human beings, think and reason and, perhaps surprisingly, how our thought processes are often fundamentally flawed and biased. This session explores the ideas presented in the book in the context of professional software development. Along this journey, the presentation also shares techniques, processes, and models that can help overcome some of the identified limitations of our decision-making abilities. Topics discussed include the “availability heuristic,” which can lead developers to choose the “latest and greatest” technology without proper evaluation; “optimistic bias,” which can blind architects so they can’t see the “unknown unknowns” within a project; and more.

It’s often a sign of an architectural approach’s maturity that anti-patterns begin to be identified and classified alongside well-established principles and practices. Daniel Bryant introduces seven deadly sins from real projects, which left unchecked could easily ruin your next microservices project.
Daniel offers an updated tour of some of the nastiest anti-patterns in microservices from several real-world projects he’s encountered as a consultant, providing a series of anti-pattern “smells” to watch out for and exploring the tools and techniques you need to avoid or mitigate the potential damage.
Topics include:
Pride: the admission of the challenges with testing in a distributed system
Envy: introducing inappropriate intimacy within services by creating a shared “canonical” domain model
Wrath: failing to deal with the inevitable bad things that occur when operating new technologies, both from the people and technical aspects
Sloth: composing services in a lazy fashion, which ultimately leads to the creation of a "distributed monolith”

JavaOne 2016 "Java, Microservices, Cloud and Containers"Daniel Bryant
Everyone is talking about building “cloud native” Java applications—and taking advantage of microservice architecture, containers, and orchestration/PaaS platforms—but there is surprisingly little discussion of migrating existing legacy (moneymaking) applications. This session aims to address this, and, using lessons learned from several real-world examples, it covers topics such when to rewrite applications (if at all), modeling/extracting business domains, applying the “application strangler” pattern, common misconceptions with “12-factor” application design, and the benefits/drawbacks of container technology.

Two years ago at Devoxx UK we talked about DevOps, what it was, why it was important and how to get started. Boy, was it scary. Now we’re wiser. More battle-scarred. The large scale of the challenge for application writers exploiting cloud and DevOps is clearer, but so is the path forward. Understanding the DevOps approach is important, but equally you must understand specific deployment technologies, security issues, operational reliability, and how to drive organisational transformation. Whether creating simple applications or sophisticated microservice architectures many of the challenges are the same. Join us to learn how you can apply this within your team and company.

Presented at OOP2016 with Erich Eichinger
The technology changes required when implementing a microservice-based application are only one part of the equation – the business and organisation will often have to fundamentally change. In an ideal world, this shouldn’t be a problem, what with the rise of agile, lean and DevOps, but in reality this is not always the situation. In this talk we will share some stories of successful (and not so successful) strategies and tactics that we have used when introducing microservices into a variety of organisations over the past four years.
Join us for a whistle-stop tour of the business and people challenges that we have experienced first hand when implementing greenfield microservice projects and also breaking down monoliths. We’ll look at ‘divided companies’ vs ‘connected companies’, determine the actual impact of conway's law, briefly touch on the lean startup/enterprise mindset, dive into change management without the management double-speak, and look at the lightweight processes needed to ensure the technical success of a microservices implementation (e.g. DevOps, CD).
The main lessons we're keen to share are from observations on a couple of microservice transformation projects we have been involved in - some where teams have been cross-functional and aligned around strategic objectives, and some where they haven't. The latter proved much more challenging, as we saw single domain models being created and shared around the codebase, unclear service/context boundaries, and ultimately people tripping over each other.

JAX London 2016: "Empathy - The hidden ingredient of good software development?"Daniel Bryant
When I ask fellow developers what they think about empathy, the answer is often “not much”. However, I believe that the skill of empathy, being able to place yourself in another’s position, is crucial to designing, building and operating software at any scale. Join me for a whistle-stop tour of the benefits of empathy, which I learned from working on a large variety of software projects over the past ten years. I will share success stories and battle scars, and suggest practical techniques that you can harness in order to help your team develop empathy.
DevoxxUK 2014 "Moving to a DevOps Mode: Easy, Hard, or Just Plain Terrifying?"Daniel Bryant
DevOps – is it for you? Heard about the wonderful ways it could benefit your organisation, but put off by the scary stories? Can you really make the transition to DevOps, and is it worth it? Listen and learn from two DevOps practitioners about their hands-on experiences in making the change. Covering a range of real life examples, this talk will explain the real business benefits to be had from using DevOps techniques, as well as the technical and personal aspects involved.
Whether it’s a small team within a startup or one of hundreds within a large organisation, this talk has practical advice on how to approach the challenge, what critical changes need to be considered, and what tools and processes are best suited for the situation. The adoption of DevOps is a game changing event for the industry. Learn why and learn how you can benefit from it too.

muCon 2016: "Seven (More) Deadly Sins of Microservices"Daniel Bryant
All is not completely rosy in microservice-land. It is often a sign of an architectural approach’s maturity that in addition to the emergence of well established principles and practices, that anti-patterns also begin to be identified and classified. In this talk Daniel will introduce the 2016 edition of the seven deadly sins that if left unchecked could easily ruin your next microservices project... This talk will take a tour of some of the nastiest anti-patterns in microservices, giving you the tools to not only avoid but also slay these demons before they tie up your project in their own special brand of hell.
Topics covered include:
Envy - introducing inappropriate intimacy within services by creating a shared domain model, and how many teams deploy and use data stores incorrectly;
Wrath - failing to deal with the inevitable bad things that occur within a distributed system;
Sloth - ignoring the importance of NFRs; and
Lust - embracing the latest and greatest technology without evaluating the impact incurred by these choices.
This is an all-new 2016 version of Daniel's popular 'deadly sins talk' that was recently presented at QCon NY. The talk received 94% highest rating, and was the fifth most attended talk at the conference. Daniel plans to continually improve the presentation based on his learnings and attendee feedback.
CraftConf 2017 "Microservices: The Organisational and People Impact"Daniel Bryant
Microservices are where it's at. Everything is easier to manage when it's micro, right? Micro code bases (less than 10 LOC), micro containers (less than 10Mb), and micro teams (less than one person???). 'Micro' things may appear to be easier to manage, but there is always a macro context, and working with people and teams is no exception. This talk presents some of the challenges the OpenCredo team have seen when implementing microservices within a range of organisations, and we'll suggest tricks and techniques to help you manage your 'micro' teams and the 'macro' level.
Topics covered include: empathy - because understanding others is at the heart of everything you do; leadership - advice on creating shared understanding, conveying strategy, and developing your team; organisational structure - from Zappos' holocracy to MegaOrg's strict hierarchy, from Spotify's squads, chapters and guilds, to BigCorp's command and control.

All is not completely rosy in microservice-land. It’s often a sign of an architectural approach’s maturity that anti-patterns begin to be identified and classified alongside well-established principles and practices. Daniel Bryant introduces seven deadly sins from real projects, which left unchecked could easily ruin your next microservices project.
Daniel offers an updated tour for 2016 of some of the nastiest anti-patterns in microservices from several real-world projects he’s encountered as a consultant, providing a series of anti-pattern “smells” you can sniff out and exploring the tools and techniques you need to avoid or mitigate the potential damage.
Topics include:
- Pride: Selfishly building the wrong thing, such as the “Inter-Domain-Enterprise-Application-Service-Bus” or a fully bespoke infrastructure platform
- Envy: Introducing inappropriate intimacy within services by creating a shared “canonical” domain model
- Wrath: Failing to deal with the inevitable bad things that occur within a distributed system
- Sloth: Composing services in a lazy fashion, which ultimately leads to the creation of a “distributed monolith”
- Lust: Embracing the latest and greatest technology without evaluating the operational impact incurred by these choices
JavaOne 2016 "Java, Microservices, Cloud and Containers"Daniel Bryant
Everyone is talking about building “cloud native” Java applications—and taking advantage of microservice architecture, containers, and orchestration/PaaS platforms—but there is surprisingly little discussion of migrating existing legacy (moneymaking) applications. This session aims to address this, and, using lessons learned from several real-world examples, it covers topics such when to rewrite applications (if at all), modeling/extracting business domains, applying the “application strangler” pattern, common misconceptions with “12-factor” application design, and the benefits/drawbacks of container technology.

The technology changes required when implementing a microservice-based application are only one part of the equation. The business and organisation will also most likely have to fundamentally change. In an ideal world, this shouldn’t be a problem - what with the rise of agile, lean and DevOps - but this is not always the situation Daniel encounters in his consulting travels. He would like to share with you some stories of successful (and not so successful) strategies and tactics he has used over the past four years when introducing service-oriented architecture into organisations.
Join Daniel for a whistle-stop tour of the business and people challenges that he has experienced first hand when implementing a greenfield microservice project, and also breaking down a monolith. You will discover ‘divided companies’ vs ‘connected companies’, determine the actual impact of conway's law, briefly touch on the lean startup/enterprise mindset, dive into change management without the management double-speak, and look at the lightweight processes needed to ensure the technical success of a microservices implementation.

Two years ago at Devoxx UK we talked about DevOps, what it was, why it was important and how to get started. Boy, was it scary. Now we’re wiser. More battle-scarred. The large scale of the challenge for application writers exploiting cloud and DevOps is clearer, but so is the path forward. Understanding the DevOps approach is important, but equally you must understand specific deployment technologies, security issues, operational reliability, and how to drive organisational transformation. Whether creating simple applications or sophisticated microservice architectures many of the challenges are the same. Join us to learn how you can apply this within your team and company.

The main lessons we're keen to share are from observations on a couple of microservice transformation projects we have been involved in - some where teams have been cross-functional and aligned around strategic objectives, and some where they haven't. The latter proved much more challenging, as we saw single domain models being created and shared around the codebase, unclear service/context boundaries, and ultimately people tripping over each other.

Microservices: Organizing Large Teams for Rapid DeliveryVMware Tanzu
SpringOne Platform 2016
Speakers: Patricia Anderson; Senior Consultant, Credera. Micah Blalock; Senior Architect, Credera. Jason Goth; Principal Architect, Credera.
A microservice architecture is pattern that is most commonly associated with larger organizations where services and teams are organized around separate business capabilities. In a project our team recently completed, we used a microservice architecture to allow us to organize a large team to develop a large analytics platform at speeds that would not have been possible using a more typical service-oriented architecture.
In this session, we discuss the organizational structure and communication and development strategies and tools to allow teams to work in parallel without drowning in process overhead and coordination costs.

When gathering requirements and performing business analysis, it is obvious that the ability to experience from within another user/customer/being's frame of reference is a valuable skill, but the same can be said when writing code. If we follow Martin Fowler’s train of thought where “any fool can write code that a computer can understand. Good programmers write code that humans can understand” we can see that empathy is at the heart of this skill. We could also argue that the rise of “DevOps” is simply both sides of the traditional divide trying to understand each other better. Developing the skill of empathy isn’t necessarily easy, but in this talk I will share my learnings, techniques and tricks for developing more effective software.

Managing a Microservices Development Team (And advanced Microservice concerns)Steve Pember
So you’re decided to make the transition to a Microservice Architecture. You’ve spent time doing the research. You’ve designed out the responsibilities of each service with your team. You’ve read and memorized the entire article Martin Fowler wrote on the subject. Now, you’re running a team that’s tasked with building some Microservices. You’re built or extracted your first services. You’ve been successfully transmitting data between these services. What next? What should you be aware of? What should keep you up at night?
In this talk we’ll begin with a brief introduction to the architecture pattern before covering some of the more advanced topics when developing Microservices, focusing primarily on team management and service design philosophy. We’ll discuss the CAP theorem and why it should be your obsession. We’ll look at how Conway’s Law should be taken seriously and how it can serve as a warning to facilitate better communication between teams. Finally we’ll examine some common pitfalls of Microservices architectures and how they can be mitigated.

BCS 2016 "Intro to Microservices (and the Seven Deadly Sins)"Daniel Bryant
The 'microservices' architectural style has taken the software development industry by storm over the past two years. Several people are arguing that this is simply classical SOA being rebranded, while others are suggesting that creating loosely-coupled composable services is simply architectural best-practice. Join Daniel for a brief introduction to the topic of microservices, and also a tour of the nastiest sins (anti-patterns) he has seen in his journey as a consultant.
Topics covered include:
* Pride - selfishly ignoring the new requirements for testing
* Envy - introducing inappropriate intimacy within services by creating a shared domain model
* Wrath - failing to deal with the inevitable bad things that occur within a distributed system
* Sloth - composing services in a lazy fashion, which ultimately leads to the creation of a Distributed Monolith

Dublin Microservice "Introduction to Service Meshes"Daniel Bryant
While service meshes may be the next "big thing" in microservices, the concept isn't new. Classical SOA attempted to implement similar technology for abstracting and managing all aspects of service-to-service communication, and this was often realized as the much-maligned Enterprise Service Bus (ESB). Several years ago similar technology emerged from the microservice innovators, including Airbnb (SmartStack for service discovery), Netflix (Prana integration sidecars), and Twitter (Finagle for extensible RPC), and these technologies have now converged into the service meshes we are currently seeing being deployed.
In this talk, Daniel Bryant will share with you what service meshes are, why they are (and sometimes are not) well-suited for microservice deployments, and how best to use a service mesh when you're deploying microservices. This presentation begins with a brief history of the development of service meshes, and the motivations of the unicorn organisations that developed them. From there, you'll learn about some of the currently available implementations that are targeting microservice deployments, such as Istio/Envoy, Linkerd, and NGINX Plus.

Topics covered include: Pride - selfishly ignoring the new requirements for testing; Envy - introducing inappropriate intimacy within services by creating a shared domain model; Wrath - failing to deal with the inevitable bad things that occur within a distributed system; Sloth - composing services in a lazy fashion, which ultimately leads to the creation of a “Distributed Monolith”; and Lust - embracing the latest and greatest technology without evaluating the operational impact incurred by these choices.
Microservice Summit 2016 "Microservices: The Organisational and People Impact"Daniel Bryant
Microservices are where it's at. Everything is easier to manage when it's micro, right? Micro code bases (less than 10 LOC), micro containers (less than 10Mb), and micro teams (less than one person???). 'Micro' things may appear to be easier to manage, but there is always a macro context, and working with people and teams is no exception. This talk presents some of the challenges the OpenCredo team have seen when implementing microservices within a range of organisations, and we'll suggest tricks and techniques to help you manage your 'micro' teams and the 'macro' level.
Topics covered include: empathy - because understanding others is at the heart of everything you do; leadership - advice on creating shared understanding, conveying strategy, and developing your team; organisational structure - from Zappos' holocracy to MegaOrg's strict hierarchy, from Spotify's squads, chapters and guilds, to BigCorp's command and control. There is a management style for everybody; and more
Lisbon DevOps: "Seven (More) Deadly Sins of Microservices"Daniel Bryant
All is not completely rosy in microservice-land. It’s often a sign of an architectural approach’s maturity that anti-patterns begin to be identified and classified alongside well-established principles and practices. Daniel Bryant introduces seven deadly sins from real projects, which left unchecked could easily ruin your next microservices project.
Daniel offers an updated tour of some of the nastiest anti-patterns in microservices from several real-world projects he’s encountered as a consultant, providing a series of anti-pattern “smells” to watch out for and exploring the tools and techniques you need to avoid or mitigate the potential damage.
Topics include:
Pride: the admission of the challenges with testing in a distributed system
Envy: introducing inappropriate intimacy within services by creating a shared “canonical” domain model
Wrath: failing to deal with the inevitable bad things that occur when operating new technologies, both from the people and technical aspects
Sloth: composing services in a lazy fashion, which ultimately leads to the creation of a "distributed monolith”
Lust: embracing the latest and greatest technology without evaluating the operational impact incurred by these choices.
Building Java applications for the IaaS cloud is easy, right? “Sure, no problem. Just lift and shift,” all the cloud vendors shout in unison. However, the reality of building and deploying cloud applications can often be different. This session introduces lessons learned from the trenches during several years of designing and implementing cloud-based Java applications, which we have codified into our Cloud Developer's “DHARMA” rules: Documented (just enough); Highly cohesive/loosely coupled (all the way down); Automated from code commit to cloud; Resource-aware; Monitored thoroughly; and Antifragile.
This session was presented at JavaOne 2014
Coming right from the Recommender Systems conference in San Francisco, I present some latest developments in the field of large scale recommendation engines and machine learning.
microXchg 2018: "What is a Service Mesh? Do I Need One When Developing 'Cloud...Daniel Bryant
While service meshes may be the next "big thing" in microservices, the concept isn't new. Classical SOA attempted to implement similar technology for abstracting and managing all aspects of service-to-service communication, and this was often realized as the much-maligned Enterprise Service Bus (ESB). Several years ago similar technology emerged from the microservice innovators, including Airbnb (SmartStack for service discovery), Netflix (Prana integration sidecars), and Twitter (Finagle for extensible RPC), and these technologies have now converged into the service meshes we are currently seeing being deployed.
In this talk, Daniel Bryant will share with you what service meshes are, why they're well-suited for microservice deployments, and how best to use a service mesh when you're deploying microservices. This presentation begins with a brief history of the development of service meshes, and the motivations of the unicorn organisations that developed them. From there, you'll learn about some of the currently available implementations that are targeting microservice deployments, such as Istio/Envoy, Linkerd, and NGINX Plus
muCon 2014 "Building Java Microservices for the Cloud"Daniel Bryant
Building microservices for the Cloud is easy, right?... Perhaps, but if you want to build effective and reliable services that not only work correctly within the Cloud, but also take advantage of running within this unique environment, then you might be in for a surprise. This talk will introduce lessons learnt over the past several years of designing and implementing successful Cloud-based Java applications which we have codified into our Cloud development ‘DHARMA' principles; Documented (just enough); Highly cohesive / lowly coupled (all the way down); Automated from commit to cloud; Resource aware; Monitored thoroughly; and Antifragile.
We will look at these lessons from both a theoretic and practical perspective using several real-world case studies involving a move from monolithic applications deployed into a data center on a 'big bang' schedule, to a platform of JVM-based loosely-coupled components, all being continuously deployed into the Cloud. Topics discussed will include API contracts and documentation, architecture, build and deployment pipelines, Cloud fabric properties, monitoring in a distributed environment, and fault-tolerant design patterns.
This presentation was delivered at muCon 2015 on 27/11/14, the microservice conference. The video can be seen here: https://skillsmatter.com/skillscasts/5938-developing-java-services-for-the-cloud
We all hear the term "DevOps" being thrown around on a daily basis, but what does it actually mean? With a little help from everyone's favourite 80's action hero, we'll undergo a whistle-stop tour of the philosophy, culture and tooling behind this buzzword, specifically aimed at Java developers. We'll also look at a real-world case study from Instant Access Technologies Ltd, and explore the key role that DevOps has played during a successful upgrade of the epoints customer loyalty platform to support increasing traffic.
The core discussion will focus on the challenges encountered as we moved from a JVM-based monolithic app deployed into a data centre on a 'big bang' schedule, to a platform of loosely-coupled components, all being continuously deployed into the Cloud. We will conclude the talk by recommending a learning path for Java developers who are interested to learn more about DevOps.

Haufe #msaday - Building a Microservice Ecosystem by Daniel Bryant OpenCredo
Daniel Bryant's slides from his talk at Haufe Microservices Architecture Day 2016.
Microservice platforms are finally becoming a reality: Mesos, Kubernetes, and a whole bunch of PaaS-style offerings are available, but the reality is that these platforms still don’t provide everything you need in order to build a fully functional microservice ecosystem. Come to this session to learn about the essential deployment, orchestration, and glue components that often have to be self-assembled. The presentation begins by looking at deployment techniques and tools and examines where to test (QA, staging, or production), how to test (integration and contracts), and how to separate deployment and release. It then discusses orchestration, configuration, and service discovery. Finally it looks at essential glue such as logging, monitoring, and alerting.

DevRelCon 2022: "Is Product Led Growth (PLG) the “DevOps” of the DevRel World"Daniel Bryant
Over the last year, the Ambassador Labs team has doubled down on their adoption of Product Led Growth (PLG), a growth model where product usage drives customer acquisition, retention, and expansion. It’s been an interesting journey for the DevRel team, who have found themselves working more closely with both the sales and growth engineering teams.
In their quest to reduce the friction of product adoption, they’re thinking more and more about the end-to-end experiences, experimentation, instrumentation, data analysis, and handoffs — much like we saw in the software development world with the adoption of DevOps breaking down barriers between engineering and operations.
The Ambassador Labs team have learned more about the value of creating hypotheses and analyzing quantitative data, but have also been reminded that there is no substitute for qualitative data and engaging human-to-human. Join Daniel for a whistle-stop tour of PLG through the DevRel lens:
– Understand how moving to PLG can impact devrel teams and the work they do: for better and worse!
– Explore how DevRel tooling and community platforms are increasingly overlapping with PLG marketer tooling
– Learn how to structure your goals, common languages, and teams for successfully adopting PLG
Fall 22: "From Kubernetes to PaaS to... err, what's next"Daniel Bryant
Developers building applications on Kubernetes today are being asked to not just code applications -- they are also responsible for shipping and running their applications, too. We often talk about needing a Kubernetes platform, but are we really looking for a PaaS? Or instead, are we looking for some kind of developer control plane with a Goldilock-sized collection of tools that provides just the right amount of platform? This talk will look back on my experience of building platforms, both as an end-user and now as part of an organization helping our customers do the same. We’ll wrap this talk with a walk-through of the CNCF ecosystem through the developer control plane lens, and look at what’s next in the future of this important emerging category.
Building Microservice Systems Without Cooking Your Laptop: Going “Remocal” wi...Daniel Bryant
Join me for a tour of coding, testing, and shipping microservices using remote-to-local “remocal” tools and techniques. You will:
- Understand the challenges with scaling container-based application development – i.e. you can only run so many microservices locally before minikube melts your laptop.
- Learn when to use various types of development practices and tooling based on your use case and requirements for production realism, speed, and practicality.
- Explore how to utilize containerized dependencies and Docker for testing, including for both apps and services you own and those you don’t.
- Learn how Telepresence can enable “remocal” development, expanding your local machine and Docker Desktop out into a remote Kubernetes cluster.

Many organizations adopt cloud native development practices with the goal of shipping features faster. The technologies and architectures may change when we move to the cloud, but the fact remains that we all still add the occasional bug to our code.
The challenge here is that many of your existing local debugging tools and practices can’t be used when everything is running in a container or deployed onto Kubernetes running in the cloud. This is where the open source Telepresence tool can help.
Join Daniel to learn about:
- Quick overview of remote-local ("remocal") options and tooling e.g. “kubectl port-forward”, Skaffold, ksync, Telepresence etc.
- An exploration of how Telepresence can “intercept” or reroute traffic from a specified service in a remote K8s cluster to your local dev machine
-- The benefits of getting a “hot reload” fast feedback loop between applications being developed locally and apps running in the remote environment

CloudBuilders 2022: "The Past, Present, and Future of Cloud Native API Gateways"Daniel Bryant
Many engineers are confused about how a cloud-native API gateway relates to Kubernetes Ingress or a Service load balancer. This talk will unravel this confusion.
An API gateway is at the core of how APIs are managed, secured and presented within any web-based system. Although the technology has been in use for many years, it has not always kept pace with recent developments within the cloud-native space.
Join Daniel Bryant in uncovering the evolution of API gateways over the past ten years and how the original problems they were solving have shifted in relation to cloud-native technologies and workflow.

DevXDay KubeCon NA 2021: "From Kubernetes to PaaS to Developer Control Planes"Daniel Bryant
Developers building applications on Kubernetes today are being asked to not just develop applications -- they are also responsible for releasing and running their applications, too. In this talk, we’ll discuss the secular shift towards what Netflix calls “Full Cycle Development” or what Google calls “Service Ownership”. With developers managing so much of the cloud-native development loop, a new class of infrastructure has emerged -- the developer control plane. We’ll explore the evolution from Kubernetes to PaaS, to the developer control planes in use today. We’ll draw on our personal experiences and podcast chats with the larger CNCF community, and discuss real-world examples of developer control planes used at New Relic, Spotify, InVision, and Twitter. We’ll wrap this talk with a walk through of the CNCF ecosystem through the developer control plane lens, and look at what’s next in the future of this important emerging category.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

2. GLUTTONY - Communication lock-in
3. GREED - What'S Mine is mine (within the organisation)…
4. SLOTH - Getting lazy with NFRs

30/01/2017 @danielbryantuk
6. New technology is great... Until it isn'T
30/01/2017 @danielbryantuk
developers with new tech be like
F*cking new technology...

This has been us
many times!
8. Evaluation - are Microservices A good fit?
• “our 'mode TWO' apps are Microservices”
– Middle-management latch on to Buzzword
– New app evolution limited by existing system
– Lipstick on the pig
• Not understanding architecture principles
– Not building around business Functionality
– Creating Mini-monoliths (no twelve factors)
• No Well-defined DevOps / SRE / Ops
– Deployment/ops free-for-all
30/01/2017 @danielbryantuk
9. Evaluation of tech - The’Spine Model
• Effective conversations make for effective
collaboration
• It's a TOOL Problem
– As a species, we have always been Tool users
and makers.
– We use _____ to get our work done
• People get stuck in a dilemma where equally
plausible options are available
• “Going up the Spine” breaks deadlock http://spinemodel.info/explanation/introduction/
10. Evaluation of tech - Fitness functions
• Great for evaluation and documentation
– Platforms / Language
– Middleware
– Data stores
• Microservices as an Evolutionary Architecture
– Neal Ford and Rebecca Parsons
30/01/2017 @danielbryantuk
11. AN example: To containerise, or not to containerise?
(dockaH, dockah, dockah... Dockah?)
30/01/2017 @danielbryantuk
17. 2. GLUTTONY - Communication lock-in
30/01/2017 @danielbryantuk
18. Rpc - not the devil in disguise
• Don'T rule out RPC (e.g. grpc)
– Sometimes the contract (and speed) are beneficial
– Human readability of JSON can be over-rated
• Sometime events are better
– Asynchronous (AP vs CP)
– durable message queues are interesting (But, No one size fits all)

19. The ESB is dead - long live the esb!
30/01/2017 @danielbryantuk
20. The ESB is dead - long live the esb!
30/01/2017 @danielbryantuk
21. The ESB is dead - long live the esb!
30/01/2017 @danielbryantuk
• Is this an ESB?
• Or an API gateway?
22. The ESB is dead - long live the API Gateway!
30/01/2017 @danielbryantuk
• Watch for the API Gateway morphing
into an Enterprise service bus
– Loose coupling is vital
• But let me be clear...
– The API Gateway pattern is awesome
– Centralise cross-cutting concerns
– Prevent wheel-reinvention (plugins)
– Check out kong, apigee, Mulesoft etc
23. 3. GREED - What'S mine is mine... (within the organisation)…
30/01/2017 @danielbryantuk
24. Previously...
• Conway'S Law
• Microservices are about people, as much as they are tech
– Maybe more
– Particularly in a migration / transformation
30/01/2017 @danielbryantuk
25. We hear this a lot...
“We’ve decided to reform our teams around squads, chapters and guilds”
• Beware of cargo-culting
– Repeat three times “We are not spotify”
• Understand the practices, principles, values etc
30/01/2017 @danielbryantuk
26. 4. SLOTH - Getting Lazy with NFRs
30/01/2017 @danielbryantuk
27. Getting lazy with non-Functional Requirements
“The driving technical requirements for a system should be identified early
to ensure they are properly handled in subsequent design”
Aidan Casey
Guiding principles for evolutionary architecture
30/01/2017 @danielbryantuk
28. Getting lazy with non-Functional Requirements
• The 'ilities' Can be (often) be an afterthought
– Availability, Scalability, auditability, testability etc
• Agile/Lean: Delay decisions to the ‘last responsible moment’
– NewsFlash - Sometimes this is up-front
• It can be costly (or prohibitive) to adapt late in the project
– Microservices don'T make this easier (sometimes more difficult)
30/01/2017 @danielbryantuk
31. 5. WRATH - Blowing up when bad things happen
30/01/2017 @danielbryantuk
32. Previously - Bring in Michael Nygard (Or some monkeys)
30/01/2017 @danielbryantuk
33. When bad things happen, people are always involved
30/01/2017 @danielbryantuk | @oakinger
34. People Pain point - How does Devops fit into this?
• http://web.devopstopologies.com/
• @ matthewpskelton
• @beerops and @sigje
• Google SRE
30/01/2017 @danielbryantuk
35. Devops - the 'fullstack engineer' myth
“I'M sorry, but if you'RE not designing the computer chips and
writing the website, then I don'T wanna hear from you”
Charity Majors (@mipsytipsy), CraftConf 2016
http://www.ustream.tv/recorded/86181845
30/01/2017 @danielbryantuk
36. Devops - define responsibilities
• Do you really want to build an
entire microservices platform?
• Focus on what matters
– Ci/CD
– Mechanical sympathy
– Logging
– Monitoring
30/01/2017 @danielbryantuk
38. 6. ENVY - The shared SINGLE domain (and Data Store) fallacy
30/01/2017 @danielbryantuk
39. Previously - One Model to Rule Them All...
• One model…
– Breaks encapsulation
– Introduces coupling
• Know your DDD
– Entities
– Value Objects
– Aggregates and Roots
30/01/2017 @danielbryantuk
41. Choose (and use) data stores appropriately
• RDBMS
– Valuable for structured data
• Cassandra is Awesome
– but don'T treat it like an RDBMS!
• Don'T build a graph with RDBMS
– Use neo4j, Titan etc
• Beware of operational overhead
30/01/2017 @danielbryantuk
42. 7. PRIDE - testing in the world of transience
30/01/2017 @danielbryantuk
43. Previously...
• Local verification
– Consumer-Driven contracts
• End-to-end
– BDD-style critical path
• Remember the test pyramid
30/01/2017 @danielbryantuk

44. Service virtualisation / API simulation
• Virtualise request/response of services
– Unavailable
– Expensive to run
– Fragile/brittle
– Non-deterministic
– Cannot simulate failures
https://dzone.com/articles/continuously-delivering-soa
30/01/2017 @danielbryantuk
45. Service virtualisation
• Classics
– CA service virtualization
– Parasoft virtualize
– HPE service virtualization
– IBM Test Virtualization server
• New (open source) kids on the block
– Hoverfly
– Wiremock
– VCR/Betamax
– Mountebank
– mirage
30/01/2017 @danielbryantuk
46. Hoverfly
• Lightweight Service virtualisation
– Open source (Apache 2.0)
– Go-based / single binary
– Written by @Spectolabs
• Flexible API simulation
– HTTP / HTTPS
– Highly performant
