Istio is widely adopted in fintech, SaaS, telecom, and enterprise cloud companies for managing microservices at scale.

1. What is Istio and why is it used?
   Istio is a service mesh that manages communication between microservices. It provides traffic management, security, and observability in Kubernetes environments.

2. What are the main components of Istio?

• Envoy → data plane proxy.

• Pilot → configures proxies for routing.

• Mixer → policy and telemetry (deprecated, replaced by extensions).

• Citadel → provides certificates for mTLS.

3. How does traffic routing work in Istio?
   Traffic is controlled using CRDs like VirtualService and DestinationRule, allowing canary rollouts, A/B testing, and traffic mirroring.

4. What is mTLS in Istio?
   Mutual TLS encrypts service-to-service communication and ensures both client and server authenticate each other.

5. What are sidecar proxies?
   Sidecar proxies (Envoy) run alongside each service pod to intercept and manage traffic without changing the app code.

6. How does Istio improve observability?
   It integrates with Prometheus, Grafana, and Jaeger to collect metrics, logs, and traces for monitoring and debugging.

7. What is circuit breaking in Istio?
   Circuit breaking prevents service overload by limiting concurrent requests or retries, ensuring system stability.

8. What is the difference between a Gateway and VirtualService in Istio?

• Gateway manages ingress/egress traffic at the mesh boundary.

• VirtualService defines routing rules for in-mesh services.

9. Can Istio work across multiple clusters?
   Yes, Istio supports multi-cluster deployments, enabling services to communicate securely across Kubernetes clusters.

10. What are the challenges of using Istio in production?
    Resource overhead, steep learning curve, and managing Istio upgrades are common challenges.
