Service-mesh technology promises to deliver a lot of value to a cloud-native application, but it doesn't come without some hype. In this talk, we'll look at what is a "service mesh", how it compares to similar technology (Netflix OSS, API Management, ESBs, etc) and what options for service mesh exist today.
KubeCon NA 2018: Evolution of Integration and Microservices with Service Mesh...Christian Posta
Cloud-native describes a way of building applications on a cloud platform to iteratively discover and deliver business value. We now have access to a lot of similar technology that the large internet companies pioneered and used to their advantage to dominate their respective markets. What challenges arise when we start building applications to take advantage of this new technology?
In this talk we'll explore the role of service meshes when building distributed systems, why they make sense, and where they don't make sense. We will look at a class of problem that crops up that service mesh cannot solve, but that frameworks and even new programming languages like Ballerina are aiming to solve
In this talk, Zack Butcher (core Istio maintainer) and I discuss the difficulty of building cloud-native applications across heterogeneous deployment environments like Kubernetes, multiple Kubernetes/OpenShift clusters, VMs, public and private cloud. Some of these challenges include routing, identity/security, and monitoring.

Evolution of integration and microservices patterns with service meshChristian Posta
Cloud-native describes a way of building applications on a cloud platform to iteratively discover and deliver business value. We now have access to a lot of similar technology that the large internet companies pioneered and used to their advantage to dominate their respective markets. What challenges arise when we start building applications to take advantage of this new technology?
In this mini-conference, we'll cover what it means to build applications with microservices, how cloud-native integration and concepts like service mesh have evolved to solve some of those problems, and how the next iteration of application development with Functions as a Service (FaaS) and serverless computing fit into this landscape.
You'll hear from industry experts Burr Sutter and Christian Posta who recently authored a book Introducing Istio Service Mesh for Microservices about these topics.
Attendees should come away from this mini-conference with the following:
Understanding of what cloud-native means and how to use it to influence positive business outcomes
How integration has evolved to create, connect and manage cloud-native APIs
How service-mesh technology like Istio can solve the challenges introduced with cloud-native applications
How the next iteration of applications deliver with FaaS and serverless computing fits in with a world of monoliths, microservices, and APIs
These talks will be of value for developers, architects, operators, platform directors, and technology leaders.
After the presentations, please stay and join Christian, Burr and your peers for networking, food and drinks. All attendees will also receive a copy of Christian and Burr's new book: Introducing Istio Service Mesh for Microservices.

API Gateways are going through an identity crisisChristian Posta
API Gateways provide functionality like rate limiting, authentication, request routing, reporting, and more. If you've been following the rise in service-mesh technologies, you'll notice there is a lot of overlap with API Gateways when solving some of the challenges of microservices. If service mesh can solve these same problems, you may wonder whether you really need a dedicated API Gateway solution?
The reality is there is some nuance in the problems solved at the edge (API Gateway) compared to service-to-service communication (service mesh) within a cluster. But with the evolution of cluster-deployment patterns, these nuances are becoming less important. What's more important is that the API Gateway is evolving to live at a layer above service mesh and not directly overlapping with it. In other words, API Gateways are evolving to solve application-level concerns like aggregation, transformation, and deeper context and content-based routing as well as fitting into a more self-service, GitOps style workflow.
In this talk we put aside the "API Gateway" infrastructure as we know it today and go back to first principles with the "API Gateway pattern" and revisit the real problems we're trying to solve. Then we'll discuss pros and cons of alternative ways to implement the API Gateway pattern and finally look at open source projects like Envoy, Kubernetes, and GraphQL to see how the "API Gateway pattern" actually becomes the API for our applications while coexisting nicely with a service mesh (if you adopt a service mesh).
Making sense of microservices, service mesh, and serverlessChristian Posta
As companies move to become digital, we can get sidetracked and distracted by some of the changes in the technology landscape. Ideally we will be harnessing technology to solve the problems we have and leverage it to deliver software faster and safer. In this talk, I'll we'll take a look at some new technology trends in the open-source communities and when and how to use them.
Come for the traffic management, stay for the securityChristian Posta
Service mesh implementations help move critical application networking functionality out of the applications and into the infrastructure. With a service mesh like Istio, for example, you can move complicated traffic routing, resiliency aspects, and top-line metric collection out of the application code. This helps you build complicated distributed systems a bit more safely. But can Istio help with solving security issues?
Christian Posta explores some of the ways Istio helps you build more secure systems with mutual TLS, OAuth 2.0, and JSON Web Token verification. Security starts with defining trust boundaries and establishing identities. Istio helps do this by leveraging SPIFEE to assign identity and lay the foundation for zero-trust application networking. Istio then leverages this identity to take over the issuance and management of workload identity documents (e.g., x509 certificates), which can then be used to provide client authentication and mTLS. Istio also helps with OAuth flows, JWT verification, RBAC/ABAC, and much more.
You may be drawn into using Istio for its traffic management functionality, but most customers Christian works with find themselves much more interested in the security aspects once they learn what they can do with it. Join in to see for yourself.

Kubernetes Ingress to Service Mesh (and beyond!)Christian Posta
Kubernetes users need to allow traffic to flow into and within the cluster. Treating the application traffic separately from the business logic allows presents new possibilities in how service to service traffic is served, controlled and observed — and provides a transition to intra cluster networking like Service Mesh. With microservices, there is a concept of both North / South traffic (incoming requests from end users to the cluster) and East / West (intra cluster) communication between the services. In this talk we will explain how Envoy Proxy works in Kubernetes as a proxy for both of these traffic directions and how it can be leveraged to do things like traffic shaping, security, and integrate the north/south to east/west behavior.
Christian Posta (@christianposta) is Global Field CTO at Solo.io, former Chief Architect at Red Hat, and well known in the community for being an author (Istio in Action, Manning, Istio Service Mesh, O'Reilly 2018, Microservices for Java Developers, O’Reilly 2016), frequent blogger, speaker, open-source enthusiast and committer on various open-source projects including Istio, Kubernetes, and many others. Christian has spent time at both enterprises as well as web-scale companies and now helps companies create and deploy large-scale, cloud-native resilient, distributed architectures. He enjoys mentoring, training and leading teams to be successful with distributed systems concepts, microservices, devops, and cloud-native application design.
An eventful tour from enterprise integration to serverless and functionsChristian Posta
In this talk, Marius (@mariusbogoevici) and I (@christianposta) discuss the value of event-driven architectures (both business and technical merits) and how the landscape of integration, streaming, and messaging and now functions/lambdas have evolved to implement EDA while balancing agility, utilization, and simplicity.
Service-mesh options with Linkerd, Consul, Istio and AWS AppMeshChristian Posta
Service mesh abstracts the network from developers to solve three main pain points:
How do services communicate securely with one another
How can services implement network resilience
When things go wrong, can we identify what and why
Service mesh implementations usually follow a similar architecture: traffic flows through control points between services (usually service proxies deployed as sidecar processes) while an out-of-band set of nodes is responsible for defining the behavior and management of the control points. This loosely breaks out into an architecture of a "data plane" through which requests flow and a "control plane" for managing a service mesh.
Different service mesh implementations use different data planes depending on their use cases and familiarity with particular technology. The control plane implementations vary between service-mesh implementations as well. In this talk, we'll take a look at three different control plane implementations with Istio, Linkerd and Consul, their strengths, and their specific tradeoffs to see how they chose to solve each of the three pain points from above. We can use this information to make choices about a service mesh or to inform our journey if we choose to build a control plane ourselves.
Leveraging Envoy Proxy and GraphQL to Lower the Risk of Monolith to Microserv...Christian Posta
If you have an existing Java monolith, you know you must take care making changes to it or altering it in any negative way. Often times these monoliths are very valuable to the business and generate a lot of revenue. At the same time, since it’s difficult to make changes to the monolith it’s desirable to move to a microservices architecture. Unfortunately you cannot just do a big-bang migration to a greenfield architecture and will have to incrementally adopt microservices. In this talk, we’ll look at using Gloo proxy which is based on Envoy Proxy and GraphQL to do surgical, function-level traffic control and API aggregation to safely migrate your monolith to microservices and serverless functions.
The Hardest Part of Microservices: Calling Your ServicesChristian Posta
When building microservices, you must solve for a number of critical functions, but the process can be incredibly complex and expensive to maintain. Christian Posta offers an overview of Envoy Proxy and Istio.io Service Mesh, explaining how they solve application networking problems more elegantly by pushing these concerns down to the infrastructure layer and demonstrating how it all works.
Multicluster Kubernetes and Service Mesh PatternsChristian Posta
Building applications for cloud-native infrastructure that are resilient, scalable, secure, and meet compliance and IT objectives gets complicated. Another wrinkle for the organizations with which we work is the fact they need to run across a hybrid deployment footprint, not just Kubernetes. At Solo.io, we build application networking technology on Envoy Proxy that helps solve difficult multi-deployment, multi-cluster, and even multi-mesh problems.
In this webinar, we’re going to explore different options and patterns for building secure, scalable, resilient applications using technology like Kubernetes and Service Mesh without leaving behind existing IT investments. We’ll see why and when to use multi-cluster topologies, how to build for high availability and team autonomy, and solve for things like service discovery, identity federation, traffic routing, and access control.
The exploration of service mesh for any organization comes with some serious questions. What data plane should I use? How does this tie in with my existing API infrastructure? What kind of overhead do sidecar proxies demand? As I've seen in my work with various organizations over the years "if you have a successful microservices deployment, then you have a service mesh whether it’s explicitly optimized as one or not."
In this talk, we seek to understand the role of the data plane and how to pick the right component for the problem context. We start off by establishing the spectrum of data-plane components from shared gateways to in-code libraries with service proxies being along that spectrum. We clearly identify which scenarios would benefit from which part of the data-plane spectrum and show how modern service meshes including Istio, Linkerd, and Consul enable these optimizations.
We consider a microservices architecture to achieve an end goal, not because it's "the cool thing to do". Every organization looking to adopt this architecture must realize (and adhere) to a set of foundational principles. Guided by those principles, we can correctly choose the technology to help support a microservices architecture and meet our end goals. This talk explains those core principles and gives you the tools needed for your microservices journey.
Lowering the risk of monolith to microservicesChristian Posta
Breaking down the monolith is a risky and difficult job. Is it even worth it? Can you improve your position with the monolith? If you do decide to decompose the monolith, how do you actually do it?
In this talk, we look at some of the difficult and nasty parts of decomposing the monolith and look at tools and techniques for lowering the risk for making these changes including tools like service mesh (Istio) and data management (Teiid spring boot, debezium.io, etc).

About the webinar:
In this webinar, two models of the NGINX Microservices Reference Architecture, the Router Mesh Model and the Fabric Model, are shown as successively more capable implementations of a service mesh architecture. We compare the MRA models to Istio, linkerd, and other service mesh architectures, and show how the NGINX Kubernetes Ingress Controller allows direct use of these other architectures. Attendees of the live webinar will have the opportunity to ask questions.
Service mesh models are an emerging standard for microservices development and deployment. Popular architectures such as Istio and linkerd use a service mesh approach, including attributes such as load balancing capability, support for authorization and authentication, and use of the circuit breaker model for resiliency.
Watch this webinar to learn:
- Key problems solved by using a service mesh model for microservices
_ How different service mesh architectures compare to each other
- How to use NGINX service mesh models - the Router Mesh Model and Fabric Model of the MRA
- How the Kubernetes Ingress Controller enables the use of NGINX in Istio, linkerd, and other service mesh models
Distributed microservices introduce new challenges: failure modes are harder to anticipate and resolve. In this session, we present a “Chaos Debugging” framework enabled by three open source projects: Gloo Shot, Squash, and Loop to help you increase your microservices’ “immunity” to issues.
Gloo Shot integrates with any service mesh to implement advanced, realistic chaos experiments. Squash connects powerful and mature debuggers (gdb, dlv, java debugging) to your microservices while they run in Kubernetes. Loop extends the capability of your service mesh to observe your application and record full transactions for sandboxed replay and debugging.
Come to this demo-heavy talk to see how together, Squash, Gloo Shot, and Loop allow you to trigger, replay, and investigate failure modes of your microservices in a language agnostic and efficient manner without requiring any changes to your code.
A service mesh is a necessary tool in your cloud native infrastructure. The era of service meshes ushers in a new layer of intelligent network services that are changing the architecture of modern applications and the confidence with which they are delivered. Istio, as one of many service meshes, but one with a vast set of features and capabilities, needs an end-to-end guide
Role of Integration and Service Mesh in Cloud Native Architecture KubeCon 2108Ballerina
Building useful services across our collection of existing applications, microservices, and now functions, we see a common theme: services must be able to communicate with each other, and solve problems like data mediation, routing, policy enforcement, security, and others. Service mesh is a technology that has emerged in container-based environments to help solve some of these problems; however, not all of them can be solved by pushing the problems to a different abstraction. Understanding the role and responsibility of service mesh and application-integration frameworks can help you successfully build useful business services on a cloud native platform. This talk will help you understand those roles and responsibilities and how service mesh and application integration co-exist to build cloud native applications.

Come to this demo-heavy talk to see how together, Squash, Gloo Shot, and Loop allow you to trigger, replay, and investigate failure modes of your microservices in a language agnostic and efficient manner without requiring any changes to your code.
A service mesh is a necessary tool in your cloud native infrastructure. The era of service meshes ushers in a new layer of intelligent network services that are changing the architecture of modern applications and the confidence with which they are delivered. Istio, as one of many service meshes, but one with a vast set of features and capabilities, needs an end-to-end guide
Role of Integration and Service Mesh in Cloud Native Architecture KubeCon 2108Ballerina
Building useful services across our collection of existing applications, microservices, and now functions, we see a common theme: services must be able to communicate with each other, and solve problems like data mediation, routing, policy enforcement, security, and others. Service mesh is a technology that has emerged in container-based environments to help solve some of these problems; however, not all of them can be solved by pushing the problems to a different abstraction. Understanding the role and responsibility of service mesh and application-integration frameworks can help you successfully build useful business services on a cloud native platform. This talk will help you understand those roles and responsibilities and how service mesh and application integration co-exist to build cloud native applications.
A presentation on why or why not microservices, why a platform is important, discovering how to break down a monolith and some of the challenges you'll face (data, transactions, boundaries, etc). Last section is on Istio and service mesh introductions. Follow on twitter @christianposta for updates and more details
We consider a microservices architecture to achieve an end goal, not because it's "the cool thing to do". Every organization looking to adopt this architecture must realize (and adhere) to a set of foundational principles. Guided by those principles, we can correctly choose the technology to help support a microservices architecture and meet our end goals. This talk explains those core principles and gives you the tools needed for your microservices journey.

From Monoliths to Services: Paying Your Technical DebtTechWell
Ever since distributed software became popular, developers have been choosing whether to use monolithic architectures or service-oriented architectures. With the advancement of cloud infrastructure and the widespread implementation of agile methodologies, the latter approach has been getting much easier. David Litvak describes how a monolithic application—due to its ever increasing technical debt—can become too big to support. He explores how to gradually reduce the size by extracting its components into smaller services, so ultimately the application is decoupled and highly distributed. David describes the current situation of cloud services and software as a service providers, offering a list of these providers for many different uses. He shares an example of an e-commerce site implementation, starting with a full-blown traditional rails monolith and then moving toward a static site with automated rebuilds with CircleCI, Contentful as a decoupled CMS, Auth0 for authentication, and Snipcart as an e-Commerce as a Service provider. Join David as he shares how to create an architecture from interconnected services.
CloudNativeLondon 2017: "What is a Service Mesh, and Do I Need One when Devel...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.
Attendees will walk away from the talk with a high-level overview of the concept, tools for deciding when best to use a service mesh, and a getting started guide if they decide this technology is the right fit for their organisation.

Comparing Sidecar-less Service Mesh from Cilium and IstioChristian Posta
Service mesh is a powerful pattern for implementing strong zero-trust networking practices, introducing better network observability, and allowing for more fine-grained traffic control. Up until now, the sidecar pattern was used to implement service-mesh capability but as the technology matures, a new pattern has emerged: sidecarless service mesh. Two prominent open-source networking projects, Cilium and Istio, have implemented a sidecar-free approach to service mesh but they both make interesting design decisions and tradeoffs. In this talk we review the architecture of both, focusing on the pros and cons of implementations such as mutual authentication, ingress, and observability.
Understanding Wireguard, TLS and Workload IdentityChristian Posta
Zero Trust Networking has become a standard marketing buzzword but the underlying principles are critical for modern microservice-style architectures. Authentication, authorizations, policy, etc. can be difficult to implement between services and do so in a maintainable way. Google invented their own transparent encryption and authorization protocol called "ALTS" back in 2007 to serve the application layer of Google's Borg workload scheduler, but we don't see others using it outside Google.
In this webinar we look at existing technology like TLS and newcomer Wireguard and see how these technologies come together to provide a secure foundation for workload identity and modern service-to-service networking.
Istio ambient mesh uses a sidecar-less data plane that focuses on ease of operations, incremental adoption, and separation of security boundaries for applications and mesh infrastructure.
In this webinar, we'll explore:
- The forces of modernization and compliance pressures,
- How Zero Trust Architecture (ZTA) can help, and
- How Istio ambient mesh lowers the barrier for establishing the properties necessary to achieve Zero Trust and compliance
Cloud-Native Application Debugging with Envoy and Service MeshChristian Posta
Microservices have been great for accelerating the software innovation and delivery, but they also present new challenges, especially as abstractions and automated orchestration at every layer make pinpointing the issue seem like walking around a maze with a blindfold. Existing tools weren’t designed for distributed environments, and the new tools need to consider how to leverage these abstraction layers to better observe, test, and troubleshoot issues.
Christian Posta walks you through Envoy Proxy and service mesh architecture for L7 data plane, the key features in Envoy that can help in debugging and troubleshooting, chaos engineering as a testing methodology for microservices, how to approach a testing and debugging framework for microservices, and new open source tools that address these areas. You’ll explore a workflow to discover and resolve microservices issues, including injecting experiments for stress testing the applications, gathering requests in flight, recording and replaying them, and debugging them step by step without affecting production traffic.
Deep Dive: Building external auth plugins for Gloo EnterpriseChristian Posta
Using the plugin framework for Ext. Auth Service in Gloo Enterprise, we can build any custom AuthN/AuthZ plugins to handle security requirements not provided out of the box.
Navigating the service mesh landscape with Istio, Consul Connect, and LinkerdChristian Posta
Service mesh has hit the cloud native computing community like a storm, and we’re starting to see gradual adoption across the enterprise. There are a handful of open source service mesh implementations to choose from, including Istio, Consul Connect, and Linkerd.
Christian Posta details why and when you may want to use a service mesh versus when you may want to just stick with a library, Netflix OSS, or application approach. He digs into three popular open source service mesh implementations and explores their goals, strengths, and weaknesses. You’ll come away with a good foundation from which to explore service mesh technology and ask the right questions to get to the right answer for them.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

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.

This concept of defining language, developing models to describe a domain, implementing those models, enforcing assertions, etc all happen within a certain context, and that context is vitally important in software. In common language, we are smart enough to resolve these types of language conflicts within a sentence because of its context. The computer doesn’t have this context. We have to make it explicit. And any context needs to have explicit boundaries.
This model needs to be “useful” ie, it should be able to be implemented. Try to establish a model that’s both useful for discussion with the domain experts and is implementable. There are infinite ways to model/think about something. Balance both masters with the model you choose.
Large complex domains may need multiple models. And really the only way to understand a language and model is within a certain context. That context should have boundaries so it doesn’t bleed or force others to bleed definitions and semantics.
Bounded context: within this space, this is the context of the language. This is what it means and it’s not ambiguous.
Central thing about a model is the language you create to express the prblem and solution very crisply. Need clear language and need boundaries.
Anti corruption layers are translations between the different models that may exist in multiple bounded contexts. They keep an internal model consistent and pure without bleeding across the boundaries.
Bounded contexts tend to be “self contained systems” themselves with a complete vertical stack of the software including UI, business logic, data models, and database. They tend to not share databases across multiple models.

Large complex domains may need multiple models. And really the only way to understand a language and model is within a certain context. That context should have boundaries so it doesn’t bleed or force others to bleed definitions and semantics.
Bounded context: within this space, this is the context of the language. This is what it means and it’s not ambiguous.
Central thing about a model is the language you create to express the prblem and solution very crisply. Need clear language and need boundaries.
Anti corruption layers are translations between the different models that may exist in multiple bounded contexts. They keep an internal model consistent and pure without bleeding across the boundaries.
Bounded contexts tend to be “self contained systems” themselves with a complete vertical stack of the software including UI, business logic, data models, and database. They tend to not share databases across multiple models.
This concept of defining language, developing models to describe a domain, implementing those models, enforcing assertions, etc all happen within a certain context, and that context is vitally important in software. In common language, we are smart enough to resolve these types of language conflicts within a sentence because of its context. The computer doesn’t have this context. We have to make it explicit. And any context needs to have explicit boundaries.
