Infrastructure Observability and Distributed Tracing
Observability goes beyond traditional monitoring by providing deep insights into system behavior through metrics, logs, and traces. Distributed tracing is essential for understanding request flows across microservices architectures. Three Pillars of Observability Metrics: Numerical measurements over time (latency, error rates) Logs: Discrete events with context Traces: Request journey across services …
Service Mesh Security and Zero Trust Networking with Istio
Service meshes like Istio provide a dedicated infrastructure layer for handling service-to-service communication. They enable zero trust networking by implementing mutual TLS, fine-grained access control, and observability without changing application code. Zero Trust Principles in Service Mesh Never Trust, Always Verify: Authenticate every request Least Privilege Access: Explicit authorization policies …
