There are many design patterns for building microservices, and most of them are wrong. Actually, that is not true. The fundamental objectives for implementing microservice systems are speed and agility. Speed, of course, is how quickly you can get things done. Regardless of what design patterns you use, if you can quickly build, fix, enhance, and rapidly evolve your microservices, you are heading in the right direction. Agility is the flexibility to move rapidly across the entire development lifecycle while living happily in production.
But we can always do better. Right?
That is what this talk is about. We will take a look at some of the more common microservice design patterns. And we will compare them to some of the alternatives. For example, what is the more common microlith design pattern, and how getting serious about loose coupling guides the evolution to ways that increase your speed and agility? We will also look at why it is micro at the code level and the data level. Finally, we will cover some practical guidelines, such as why your microservices should do the least amount of work while your users are waiting and techniques for doing that.
Istio as an Enabler for Migrating Monolithic Applications to Microservices v1.3Ahmed Misbah
Migrating application architectures to microservices is considered a key area of transformation in the IT world. Modernizing legacy applications to Kubernetes-based microservices can prove to be very challenging if not planned correctly, taking into consideration the right technologies and enablers.
This session explains how Istio can be used as an enabler for modernizing legacy monolithic applications to microservices. Topics covered in the presentation will include:
1- Advantages of migrating to microservices and service mesh
2- Designing a microservice application based on splitting an existing monolithic application
3- Implementing microservices iteratively as a strangler fig application with Istio
An ode to the underrepresented and underused pattern of events and asynchrony in the design and development of Microservices.
Prepared by Saul Caganoff, and delivered by Saul at Melbourne Microservices, and by Yamen Sader at Sydney Microservices.

This presentation explores the Microservices architecture style. Although there is no precise definition of this architectural style (some argue Microservices is not an architectural style, just another term for SOA architectures), there is increasing agreement this approach is useful in implementing highly scalable, robust and configurable software systems.
We’ll attempt to clarify the topic from a purely architectural point of view dispelling some myths in the process.
NATS was created by Derek Collison, founder and CEO
of Apcera, who has spent 20+ years designing, building, and using publish-subscribe messaging systems.

Without Resilience, Nothing Else MattersJonas Bonér
It doesn’t matter how beautiful, loosely coupled, scalable, highly concurrent, non-blocking, responsive and performant your application is—if it isn't running, then it's 100% useless. Without resilience, nothing else matters.
Most developers understand what the word resilience means, at least superficially, but way too many lack a deeper understanding of what it really means in the context of the system that they are working on now. I find it really sad to see, since understanding and managing failure is more important today than ever. Outages are incredibly costly—for many definitions of cost—and can sometimes take down whole businesses.
In this talk we will explore the essence of resilience. What does it really mean? What is its mechanics and characterizing traits? How do other sciences and industries manage it, and what can we learn from that? We will see that everything hints at the same conclusion; that failure is inevitable and needs to be embraced, and that resilience is by design.
Mastering Chaos - A Netflix Guide to MicroservicesJosh Evans
QConSF 2016 Abstract:
By embracing the tension between order and chaos and applying a healthy mix of discipline and surrender Netflix reliably operates microservices in the cloud at scale. But every lesson learned and solution developed over the last seven years was born out of pain for us and our customers. Even today we remain vigilant as we evolve our service architecture. For those just starting the microservices journey these lessons and solutions provide a blueprint for success.
In this talk we’ll explore the chaotic and vibrant world of microservices at Netflix. We’ll start with the basics - the anatomy of a microservice, the challenges around distributed systems, and the benefits realized when integrated operational practices and technical solutions are properly leveraged. Then we’ll build on that foundation exploring the cultural, architectural, and operational methods that lead to microservice mastery.
The Hardest Part of Microservices: Your Data - Christian Posta, Red HatAmbassador Labs
Christian Posta, principal architect at Red Hat discusses how to manage your data within a microservices architecture at the 2017 Microservices.com Practitioner Summit.
Is a secure cloud possible or an neverending rat-race? We know the debate around “The Cloud Is Just Someone Else's Computer.” The cloud is an technology ecosystem that provided us so much more options than time-share mainframe, multi-user unix systems or patterns as CORBA and RPC could provide us. I'll introduce you into the concept of Variety known from Requisite Variety. One of the key attributes of an antifragile IT systems. This concept will help you in design decision on the risk mitigation in the cloud.
Microservices for Mortals by Bert Ertman at Codemotion DubaiCodemotion Dubai
With popular poster children such as Netflix and Amazon, Microservices based architecture seems to be the killer approach to 21st century architectures. But are they only for Hollywood Coders pioneering on the bleeding edge of our profession? Or are they ready to be used for your projects and your customers? I will go over the benefits, but more so the pitfalls, of using a Microservices based architecture. What impact does it have on your organization, your applications, on dealing with scale and failures, and how do you prevent your landscape from becoming an unmaintainable nightmare.
Microservices – or micro-services – may simply be a term for something already being used, but by giving something a name and defining it, we sometimes give ourselves the advantage of recognizing a tool we perhaps should be including in our systems.
This presentation is about my talk on TDC 2015. It is an invite for you to understand and know more about reactive programming and vert.x to develop your microservices.

DDD SoCal: Decompose your monolith: Ten principles for refactoring a monolith...Chris Richardson
This is a talk I gave at DDD SoCal.
1. Make the most of your monolith
2. Adopt microservices for the right reasons
3. It’s not just architecture
4. Get the support of the business
5. Migrate incrementally
6. Know your starting point
7. Begin with the end in mind
8. Migrate high-value modules first
9. Success is improved velocity and reliability
10. If it hurts, don’t do it
In an environment where software is constantly changing and new versions of a library should be distributed across thousands of projects, how can you know that your projects are using the right version of a given dependency? What if a OSS library introduces a security vulnerability and you need to make sure that no one is using it in your company? What if an internal library introduces a bad change and you need everyone to upgrade/downgrade? Automating these for hundreds or thousands of engineers is crucial.
At Netflix, engineers are not immune to the cost of dependency updates. Library owners publish new versions of their code without a comprehensive understanding of the organizational impact. Application owners ingest new library versions that can fail in obvious or subtle ways, leading to decreased confidence and slower organizational velocity. But these are problems we understand, and tooling can help. After years of evolving our build, we've developed a few conceptual models of dependency management. Dependency management is hard, and in all cases there are compromises, and you the build owner should be conscious of which choices you're making and what else is available.
On this session, I'll introduce some tools we've developed at Netflix which attack dependency issues on a large scale to make it easier for every JVM engineer at Netflix and how we react to the scenarios mentioned above.
Elastically scalable architectures with microservices. The end of the monolith?Javier Arias Losada
In the last years the microservices architecture style has been gaining traction with some companies such as Netflix, Yelp, Gilt, PayPal. Many of that companies abandoned their previous monolithic architecture and moved to a microservices approach.
Does that mean that monolithic architectures are a thing of the past?
In this talk we will review some key microservices concepts (and misconceptions), search for the essence of microservices architectures and discuss about different approaches to implement them from the industry.
These days, you can’t swing a dry erase marker without hitting someone talking about microservices. Developers are studying Eric Evans' prescient book, Domain-Driven Design. Teams are refactoring monolithic apps, looking for bounded contexts and defining a ubiquitous language. And although there have been countless articles, videos, and talks to help you convert to microservices, few have spent any appreciable time asking if a given application should be a microservice. In this talk, I‘ll show you a set of factors you can apply to help you decide if something deserves to be a microservice or not. We’ll also look at what we need to do to maintain a healthy micro(services)biome.

JAXLondon 2015 "DevOps and the Cloud: All Hail the (Developer) King"Daniel Bryant
Last year 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 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. How to exploit them and how they effect the design of applications. Whether creating simple applications or sophisticated microservice architectures many of the challenges are the same.
Presented at JAXLondon 2015 with Steve Poole
It's easy to say... Microservices! Reality is we need to learn and apply concepts coming from many disciplines like SOA, EDA and DDD just to name a few! Mix them with some ALM and technical processes around Packaging and Deploying... and maybe then you get a true Microservices solution.
Applications of different size, business domain and criticality suffer from a huge set of issues, be it boring enterprise software, “Highly-Loaded” social network or a cozy startup. In this talk Eduards will cover Software Architecture issues that he finds the most prevailing nowadays and what you can do with that. Think big!
Surviving as a Monolith in a Microservices World - by Blair Olynyk, HyperwalletHyperwallet
Today’s application architects are striving for the panacea that is a microservice architecture. However, it’s not like you can come into the office on a Monday morning, turn on the lights, and magically turn your current solution into a microservice architecture by the time you turn off the lights. So, what do you do if your organization is heavily invested in an SOA or monolithic architecture? In this talk, Head Software Architect, Blair Olynyk, will explain how Hyperwallet is preparing for microservice by remaining agile, using a strong set of processes, and the fundamentals of loose coupling.
Slides for my keynote at incontrodevops.it, where I talked about distributed architectures, microservices, kubernetes and cloud native environments. All to get to the question: are microservices worth it?
Slides for the presentation on Microservices -- The Easy Way is the Wrong Way. The presentation is meant to show that to do microservices well a lot of other details are required.

Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

26. Monoliths vs Microservices? Adopting monoliths
again?
- The initial incarnation of microservices failed
- “Correctly built distributed systems” should
raise an alarm!
27. Monoliths vs Microservices?
“[...] a monolithic application puts all its functionality into a single process and
scales by replicating the monolith on multiple servers”,
whilst
“[...] a microservices architecture puts each element of functionality into a separate
service and scales by distributing these services across servers, replicating as
needed”.
Martin Fowler
30. Monoliths vs Microservices? Main ideas
- Start with a monolith
- Don’t forget to modularize it (Domain-Driven Design)
31. Monoliths vs Microservices? Main ideas
- Start with a monolith
- Don’t forget to modularize it
- Decompose into separate components when needed
(microservices)
38. 10 Principles of good design
1. Asynchronicity
2. Autonomy

4. Single Responsibility Principle
5. Stateless
6. Distribution transparency
7. Past nature of information
8. Eventual consistency
9. Monitoring, observability and
distributed tracing
10. Recovering from errors
49. How to gain autonomy?
- The isolation level between them
50. How to gain autonomy?
- The isolation level between them
- The capacity to act independently in doing business
tasks
51. How to gain autonomy?
- The isolation level between them
- The capacity to act independently in doing business tasks
- The capacity to fail independently
52. How to gain autonomy?
- The isolation level between them
- The capacity to act independently in doing business tasks
- The capacity to fail independently
- The collaboration level between microservices
54. Monolith vs microservices - autonomy POV
In the case of monolith:
- multiple software constructions
deployed as a single deployment unit
- no isolation between them
- components are not acting
autonomously
- if one fails => the rest will also fail
55. Monolith vs microservices - autonomy POV
In the case of monolith:
- multiple software constructions
deployed as a single deployment unit
- no isolation between them
- components are not acting
autonomously
- if one fails => the rest will also fail
In the case of microservices:
- individual deployment units
- isolated components
- autonomy
- if one will fail => the rest of other will
still be working
58. Bulkheading
- it covers both monoliths and microservices
- isolates application into separate pools => if one fails, the
rest will not

62. A microservice asks: What is my responsibility ?!
- a microservice/monolith’s module must have a
single responsibility (SRP)
63. A microservice asks: What is my responsibility ?!
- a microservice/monolith’s module must have a single
responsibility (SRP)
- better decoupling
64. A microservice asks: What is my responsibility ?!
- a microservice/monolith’s module must have a single
responsibility (SRP)
- better decoupling
- higher autonomy degree
77. Past nature of information
- think in terms of past events containing pieces of
information
78. Past nature of information
- think in terms of past events containing pieces of
information
- avoid querying for “current” state
79. Past nature of information
- think in terms of past events containing pieces of
information
- avoid querying for “current” state
- embrace commands (eg: “enrollNewCustomer”)
80. Past nature of information
- think in terms of past events containing pieces of
information
- avoid querying for “current” state
- send and receive commands (eg:
“enrollNewCustomer”)
- react to and emit events (eg: “customerEnrolled”)
84. What about transactions?
- leverage Domain-Driven Design
- one aggregate/microservice or monolith’s module
85. What about transactions?
- leverage Domain-Driven Design
- one aggregate/microservice or monolith’s module
- aggregate’s rule of thumb about transactions
86. What about transactions?
- leverage Domain-Driven Design
- one aggregate/microservice or monolith’s module
- aggregate’s rule of thumb about transactions
- forget about 2PC and heuristic decisions

110. Today’s conclusions
- starting point for creating individual microservices
- easy to reason with
- “A microservice is not of much use, they always come
as systems” - Jonas Bonér
