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 ...

Building Resilient Systems: Fault Tolerance and Recovery Resilient systems stay available when parts fail. Fault tolerance means the system keeps working even if some components fail. Recovery is the plan to restore full function after an outage. Together, these ideas help teams meet user needs, even in rough conditions. Design decisions at every layer matter. Hardware, networks, services, and data all deserve attention. Clear health checks, fast detection, and quick recovery actions prevent small problems from becoming big outages. ...
