Service management with Anthos Service Mesh

Anthos Service Mesh is a fully managed service mesh for microservices architectures. It is based on an open source project, started by Google, called Istio. Google is gradually integrating Istio's functionalities with other Google Cloud services such as the Cloud operations suite to provide an enterprise-grade service mesh offering. Let's have a look at Istio first to understand how it works so we can better understand Anthos Service Mesh.

Istio

Istio is an open source service mesh project. It runs in Kubernetes but may also integrate with traditional workloads hosted on VMs. It provides a programable and application-aware network. With the use of open source Envoy proxies, the traffic between microservices is intercepted and can be controlled, secured, and observed. This allows us to gain full control and visibility of the traffic between complex microservice-based applications. As we see in Figure 8.12, Istio injects Envoy...
