Istio

Step 1: Deploy the new version of the application alongside the existing version.

Step 2: Configure a VirtualService to route a small percentage of traffic to the new version.

Step 3: Monitor the performance of the new version using Istio's telemetry features.

Step 4: Gradually increase the percentage of traffic to the new version as confidence grows.

Step 1: Enable mTLS for all services in the mesh using PeerAuthentication.

Step 2: Configure AuthorizationPolicy to define which services are allowed to access other services.

Step 3: Deploy the configuration to your Kubernetes cluster.

Step 4: Monitor the mTLS connections.

Step 1: Define a request rate limit using EnvoyFilter.

Step 2: Apply the EnvoyFilter to the service.

Step 3: Monitor the rate limiting metrics.

Step 4: Adjust the rate limit based on the observed traffic patterns.

Step 1: Use Istio's telemetry data to identify slow or failing services.

Step 2: Analyze traces to understand the flow of requests through the system.

Step 3: Examine logs to identify error messages or other issues.

Step 4: Use the gathered information to diagnose and resolve the performance problem.

Step 1: Deploy a 'canary' version of your service with the new feature.

Step 2: Route a small percentage of real user traffic to the canary.

Step 3: Monitor the canary's performance and error rates closely.

Step 4: If the canary performs well, gradually increase the traffic percentage until it replaces the old version.
