Have you encountered Istio?

Yes, I have worked with Istio — it is a service mesh that helps manage network interactions between microservices in Kubernetes and other environments.

Main features of Istio:

• Traffic management (routing, load balancing, fault injection)
• Security (mTLS, authentication, and authorization)
• Observability (tracing, metrics, logging)

For example, with Istio, you can set up canary releases by gradually directing some traffic to a new version of a service, or ensure traffic encryption between services without changing the code.

In my practice, I used Istio for monitoring and managing traffic in a production cluster, as well as for configuring security policies between services.
