Istio as an enabler for migrating Monolithic apps to Microservices
summary
Claims a repeatable path from monolith to microservices that keeps the legacy app running while routing fractions of traffic to new services using Envoy sidecar proxies and Helm on Kubernetes. Demonstrates canary releases and traffic splitting, collects metrics and traces via Prometheus + Grafana and request-id tracing, and uses Mixer for telemetry aggregation. Reports zero‑downtime cutovers in staged migrations but warns about auto‑injection, CNI/eBPF alternatives, multi‑cloud limitations and the extra resource and config overhead.
