Istio

/IS-tee-oh/ · noun · Development · Origin: 2017

Definitions

  1. An open-source service mesh platform that provides traffic management, security, and observability for microservices running on Kubernetes. Istio deploys an Envoy proxy sidecar alongside each service to intercept all network traffic. Powerful but notorious for its operational complexity and steep learning curve.

    In plain English: A popular but notoriously complex tool for managing how microservices communicate in Kubernetes — adds powerful features at the cost of significant operational overhead.

    Example: We spent three months getting Istio working correctly and another three understanding why random pods kept crashing — turns out the sidecar was OOMing.
