Container Networking and Service Mesh Questions

Comprehensive design and operation of container networking and service mesh architectures for production systems. Topics include container network models and container network interface plugins, service discovery and domain name resolution for containers, overlay and underlay networking trade offs, Kubernetes proxy modes and load distribution, network policy design for tenant isolation and security, ingress and east west traffic patterns, sidecar proxy deployment models, service mesh capabilities such as traffic management, retries, circuit breaking, fault injection, mutual Transport Layer Security and fine grained authorization, distributed tracing and telemetry integration, policy enforcement and rate limiting, performance and latency trade offs introduced by proxies, operational debugging techniques including packet capture and connection tracing, and migration strategies to adopt or roll back service meshes safely.
