Istio is an open-source service mesh that provides a uniform way to connect, secure, control, and observe microservices. It runs as a control plane with data‑plane proxies (Envoy) to handle traffic routing, security, and telemetry without code changes.

Use cases

• Implement zero‑trust mTLS between microservices
• Perform advanced traffic routing like canary releases and A/B testing
• Collect distributed tracing and metrics for observability
• Enforce fine‑grained access policies across services
• Simplify service discovery and load balancing in Kubernetes clusters
• Migrate legacy applications to a cloud‑native architecture with minimal code changes

When to choose

• You need a full‑featured service mesh for Kubernetes or hybrid environments
• You want built‑in traffic management, security, and observability without modifying application code
• Your organization requires policy enforcement and compliance across many microservices
• You prefer an open, CNCF‑graduated project with a large ecosystem and community support

When to avoid

• Your deployment is small and the overhead of a mesh outweighs its benefits
• You are using a platform that already provides a native service mesh you cannot replace
• You need a lightweight proxy solution with minimal resource consumption
• Your environment does not support Kubernetes or container orchestration
