Article 1Designing for High Availability: The Road to 99.99% ReliabilityTLDR: High Availability (HA) is the art of eliminating Single Points of Failure (SPOFs). By using Active-Active redundancy, automated health checks, and global failover via GSLB, you can achieve "Four9 minArticle 2System Design Advanced: Security, Rate Limiting, and ReliabilityTLDR: Three reliability tools every backend system needs: Rate Limiting prevents API spam and DDoS, Circuit Breakers stop cascading failures when downstream services degrade, and Bulkheads isolate fai16 minArticle 3Service Mesh Pattern: Control Plane, Data Plane, and Zero-Trust TrafficTLDR: A service mesh intercepts all service-to-service traffic via injected Envoy sidecar proxies, letting a platform team enforce mTLS, retries, timeouts, and circuit breaking centrally — without cha15 minArticle 4Dead Letter Queue Pattern: Isolating Poison Messages and Recovering SafelyTLDR: A dead letter queue protects throughput by moving repeatedly failing messages out of the hot path. It only works if retries are bounded, triage has an owner, and replay is a deliberate workflow 14 minArticle 5Cloud Architecture Patterns: Cells, Control Planes, Sidecars, and Queue-Based Load LevelingTLDR: Cloud scale is not created by sprinkling managed services around a diagram. It comes from isolating failure domains, separating coordination from request serving, and smoothing bursty work befor16 minArticle 6Circuit Breaker Pattern: Prevent Cascading Failures in Service CallsTLDR: Circuit breakers protect callers from repeatedly hitting a failing dependency. They turn slow failure into fast failure, giving the rest of the system room to recover. TLDR: A circuit breaker 17 min
