In a microservice world things become more complex. Platforms such as Kubernetes address a lot of the complexity, they handle resource isolation and utilization, networking and deployments nicely. But still, a lot of the involved complexity such as load balancing, rollout scenarios, circuit breaking, retries, rate limiting, observability, tracing and transport security is still left up to the development teams.
Of course you can address all of these challenges in your microservices programmatically using popular open source components such as Hystrix, Ribbon, Eureka, the EFK Stack, Prometheus or Jaeger. But unfortunately, this approach can quickly lead to excessive library bloat, and suddenly your microservices are not quite so micro anymore.
All this might seem acceptable if you are on a single, consistent development stack like Java EE or Spring Boot. But tackling these complexities becomes even more challenging if you are dealing with multiple stacks and multiple frameworks. Or you might even deal with legacy applications that you can’t modify to retrofit these requirements.
Istio to the rescue. It is a so called service mesh that addresses many of the cross-cutting communication concerns in a microservice architecture. Think of Istio as AOP (aspect oriented programming) for microservice communication. Instead of implementing everything directly within your services, Istio transparently injects and decorates the desired concerns into the individual communication channels.
This session provides an overview of the Istio system and how it addresses the inherent complexities in microservice architectures. We will briefly discuss the conceptual architecture and the main building blocks of Istio. Then we will dive right into several showcases that are deployed on a live Kubernetes cluster to demonstrate the different traffic management features, as well as diagnosability and security.
