Understanding Istio and the service mesh
Application modernization nowadays requires us to have distributed microservice applications running on several infrastructures spread across multi-cloud and on-premises environments. Due to the distributed nature of these applications, interconnecting microservices has become very challenging and complicated. One of the most well-known and adopted solutions for microservice networking is Istio. Istio lets you easily interconnect microservices within a Kubernetes cluster in a sort of overlay network called a service mesh. The great thing about service meshes is that developers do not have to implement network functionalities to discover microservices, route traffic to and from a microservice, authenticate and authorize API calls, and monitor how traffic is flowing across your distributed application. Indeed, Istio has the following features:
- Traffic management: You can decide how traffic and API calls can be routed across your service...
