Service-Discovery

Container Networking Essentials Containers run in shared environments, so knowing how they talk to each other and to the outside world helps avoid surprises. Start with the basics: each container gets a network interface, an IP, and a way to reach other services. Most projects use a container runtime plus a networking layer called a CNI (Container Network Interface) to manage these connections. Key concepts to know Namespaces and isolation keep traffic separate between containers and processes. IP addressing and a CNI plugin decide how containers receive addresses and routes. Service discovery and DNS give stable names to dynamic containers, so apps can find each other. Port mapping and NAT let internal services reach the outside world, and vice versa. Pod networking in Kubernetes assigns each pod its own IP and defines how pods talk within the cluster. Overlay networks add network paths across hosts, useful in multi-host setups. Network policies control which workloads may talk to others and when, improving security. Observability helps you see traffic flow with simple metrics and logs. Practical takeaways ...

Networking Essentials for Building Reliable Systems Networks connect services and apps across rooms, clouds, and devices. A reliable system depends on clear, predictable communication. Small delays or failed calls can ripple through, so it helps to plan how services talk to each other. Core concepts Latency, jitter, and throughput describe how fast data moves. Keep requests simple and consider compression when helpful. Timeouts matter. Set sensible client and server timeouts to avoid waiting forever. Retries should be cautious. Use exponential backoff and cap the total time spent retrying. Idempotence means repeated requests have the same effect. This helps when networks slip or retries happen. Rate limits protect services from overload and help lines stay responsive. Reliability patterns ...
