Simplifying the microservice landscape

As we have seen in the preceding section, Istio comes with components that overlap with components currently used in the microservice landscape in terms of functionality:

The Istio ingress gateway can act as an edge server, an alternative to a Kubernetes Ingress controller
The Jaeger component that comes bundled with Istio can be used for distributed tracing instead of the Zipkin server that we deploy together with the microservices

In the following two subsections, we will get an overview of why and how the Kubernetes Ingress controller is replaced with an Istio ingress gateway, and our Zipkin server is replaced with the Jaeger component that comes integrated with Istio.

Replacing the Kubernetes Ingress controller with an Istio ingress gateway

In the previous chapter, we introduced the Kubernetes Ingress controller as an edge server (refer to the Replacing Spring Cloud Gateway section in Chapter 17, Implementing...
