Using Istio Gateway to Route Traffic to Microservices on Amazon EKS

Описание: One of the glaring challenges of deploying microservices to Kubernetes is figuring out optimal and secure network communication from outside the cluster to your services inside of it and network communication between the services themselves. In some scenarios, we can use Kubernetes services like LoadBalancers and NodePorts to expose our applications to the world. However, there are use cases where this isn't the best approach. A better and safer practice is establishing a single point of entry into your cluster that can also manage HTTP traffic and smart routing. I'll discuss how a tool like Istio can help with accomplishing this. Istio is an open-source implementation of a service mesh and is an agnostic middleware solution that handles network communication for your applications. You can use Istio gateways and virtual services to open a doorway to the microservices in your cluster and securely route that traffic to the relevant destination services.

In this video, I'll talk about how you can use the Istio ingress gateway and virtual services to establish a single entry point into your cluster, and route traffic to your microservices in an Amazon EKS cluster.
