Part 1 Understanding Istio

What programming language do you use to implement your microservices or applications? Java? NodeJS? Golang? Whichever language or framework you use will eventually have to communicate with services over the network. The network is a perilous place for applications. What do you do for service discovery? timeouts? retries? circuit-breaking? security?

Istio is an open source service mesh that helps solve service-to-service connectivity challenges in your cloud and microservices environment regardless of what language or framework you use. In chapters 1-3, we explain why a service mesh is critical infrastructure for a microservices and cloud-native application architecture, how Istio helps, and what you can expect from the rest of the book. Istio is built on an open source proxy named Envoy, which we cover in detail to set the foundations for the rest of the Istio functionality covered in future chapters.
