Container deployment platforms are a boring part of our infrastructure. The exciting parts, unfortunately, happen when services actually try communicating and working together to accomplish some business function. The service mesh approach helps make service communication boring, with capabilities that include retries, load balancing, timeouts, deadlines, circuit breaking, mutual TLS, service discovery, and distributed tracing. Istio—an open source project initially sponsored by Google, Lyft, and IBM—has become a popular way of implementing a service mesh, and the project has a growing community of users and contributors.
Christian Posta leads a deep dive into Istio. You’ll learn how Istio works and how to debug issues as you take a step-by-step walk-though of Istio’s components. Christian starts by introducing Envoy, Istio’s default service proxy, teaching you how to configure it and how it implements resilience functionality. You’ll then deploy each component of the Istio control plane—Istio Pilot, Istio Ingress, Istio Gateway, and Istio Mixer—giving you a firm understanding of what they do and how to use them. You’ll also discover how to debug Envoy configurations and how best to replace resilience features handled by library-specific frameworks (Netflix OSS, Finagle, etc.).
Christian Posta (@christianposta) is field CTO at solo.io, where he helps companies create and deploy large-scale, resilient, distributed architectures—many of what we now call serverless and microservices. Previously, Christian spent time at web-scale companies. He’s well known in the community as an author—of Istio in Action (Manning) and Microservices for Java Developers (O’Reilly)—a frequent blogger, a speaker, an open source enthusiast, and a committer on various open source projects, including Istio and Kubernetes. He enjoys mentoring, training, and leading teams to be successful with distributed systems concepts, microservices, DevOps, and cloud native application design.
