Open Source Networking Days- Service Mesh

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.

Modern application architectures are embracing public clouds, microservices, and container schedulers like Kubernetes and Nomad. These bring complex service-to-service communication patterns, increased scale, dynamic IP addresses, ephemeral infrastructure, and higher failure rates. These changes require a new approach for service discovery, configuration, and segmentation. Service discovery enables services to find and communicate with each other. Service configuration allows us to dynamically configure applications at runtime. Service segmentations lets us secure our microservices architectures by limiting access. In this talk, we cover these challenges and how to solve them with Consul providing as a service mesh.

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.

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.

This document discusses microservices architecture and related concepts. It begins with an overview of microservices compared to earlier SOA approaches. Key aspects of microservices covered include developing single applications as independent services, common misconceptions, principles like single responsibility, and defining appropriate service boundaries. The document also discusses messaging approaches in microservices including REST, gRPC, and asynchronous messaging. Other sections cover organizing microservices, deployment, security, data management, governance, bridging monolithic and microservice systems, and implementing a service mesh.

SpringOne Platform 2017 Ramiro Salas, Pivotal The concept of a service mesh represents a paradigm shift on application connectivity for distributed systems, with wide implications for analytics, policy and extensibility. In this talk, we will explain what a service mesh is, the power it brings to microservices, and its impact on Cloud Foundry and K8s, both separately and together. We will also discuss the implications for the traditional network infrastructure, and the shifting of responsibilities from L3/4 to L7, and our current thinking of using Istio to integrate all abstractions.

Speaker: Owen Garrett Sr. Director, Product Management NGINX, Inc. On-Deman Link: https://www.nginx.com/resources/webinars/need-service-mesh/ About the webinar: Service mesh is one of the hottest emerging technologies. Even though it’s a nascent technology, many vendors have already released their implementation. But do you really need a service mesh? Attend this webinar to learn about the levels of maturity on the journey to modernizing your apps using microservices, and the traffic management approaches best suited to each level. We’ll help you figure out if you really need a service mesh.

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

- Integration microservices are used to compose other microservices and APIs to create new services, similar to the concept of "miniservices". They help integrate web APIs, legacy systems, and microservices. - Technologies for building integration microservices include frameworks like SpringBoot and Dropwizard, Apache Camel, and the Ballerina programming language. Ballerina is designed specifically for integration and allows graphical composition of services and connectors. - Integration microservices are an important part of microservices architecture as they handle service compositions and orchestration between multiple microservices and external APIs.

Developing and managing hundreds (or maybe thousands) of microservices at scale is a challenge for both development and operations teams. We have seen over the last years the appearance of new frameworks dedicated to deliver ‘Cloud Native’ applications by providing a set of (out of box) building blocks. Most of these frameworks integrate microservices concerns at the code level. Recently, we have seen the emerging of a new pattern known as sidecar or proxy promoting to push all these common concerns outside of the business code and provides them on the edge by integrate a new layer to the underlying platform called Service Mesh. Istio is one of the leading Service Mesh implementing sidecar pattern. We will go during the presentation throw the core concepts behind Istio, the capabilities that provides to manage, secure and observe microservices and how it gives a new breath for both developers and operations. The presentation will be guided by a sequence of demo exposing Istio capabilities.

The document discusses how digital transformation is driving changes in enterprise integration needs, moving from centralized integration middleware towards decentralized microservices and micro-integrations. It introduces Ballerina, a new programming language from WSO2 that can be used to build independent, lightweight integration microservices visually or textually. WSO2's next generation integration platform will use Ballerina to replace the ESB and address modern integration requirements around agility, orchestration, APIs, microservices, performance and scalability.

Kasun Indrasiri discussed the evolution of application architectures from monolithic to microservices and the need for integration between microservices. He described how Netflix, Uber, and PayPal implement service compositions in their microservice architectures. He then introduced the concept of integration or composite microservices that are used to integrate APIs, legacy systems, databases, and other microservices. Ballerina was presented as an open source framework for building these types of integration microservices with features like graphical definitions and network abstractions. Service meshes were also briefly mentioned as tools for managing inter-service communications at scale.

Microservice composition or integration is probably the hardest thing in microservices architecture. Unlike conventional centralized ESB based integration, we need to leverage the smart-endpoints and dumb pipes terminology when it comes to integrating microservices. There two main microservices integration patterns; service orchestration (active integrations) and service choreography (reactive integration). In this talk, we will explore on, Microservice Orchestration, Microservice Choreography, Event Sourcing, CQRS and how Kafka can be leveraged to implement microservices composition

It then covers common connectivity protocols for IoT, steps to activate a device on a gateway, and patterns for routing telemetry and commands via a service bus. The document demonstrates connecting a Raspberry Pi device and a prototype solar panel system that sends telemetry and receives commands via a gateway and Azure services. It also mentions Microsoft's initiatives in the IoT space like Project Reykjavik and the Intelligent Systems Service.

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.

Istio is an open source service mesh that provides traffic management, service identity and security, observability and policy enforcement capabilities for microservices. At its core, Istio uses the Envoy proxy as a sidecar for each microservice to mediate all inbound and outbound traffic. It provides features like load balancing, failure recovery, metrics and monitoring out of the box without requiring any code changes to the application. Istio's control plane components like Pilot, Mixer and Citadel manage the proxy configuration, collect telemetry, and handle authentication tasks.

This slide deck explains why we need microservices and how we can develop microservices using opensource microservice frameworks.

It's been two years since we introduced the Istio project to the Triangle Kubernetes Meetup group. This presentation will be a brief re-introduction of the Istio project, and a summary of the updates to the Istio project since its 1.0 release.

This presentation gave an introduction to Istio and service mesh, as well as a description of how service mesh fits in with API Management.

This speech about micro-services, approaches, and practices in their construction. How to effectively build communication between micro-services and what approaches are commonly used for this. We will talk a little about distributed transactions. Will touch the topic of infrastructure, monitoring, and scaling components. I want to inspire my listeners to develop themselves in the direction of backend development. Force to look towards scalable application architecture. You cannot find this information in the documentation :) This speech will also consist of real-life examples.

Kubernetes provides an API and objects for automating infrastructure components like storage, services, load balancing, and more. Istio implements a service mesh on top of Kubernetes to provide additional features for traffic control, including load balancing, tracing, authentication, and canary testing through an Envoy sidecar proxy. A service mesh separates these networking and traffic concerns from Kubernetes' focus on computing and high availability.
