Understanding high‑availability architectures involves mastering replication and fail‑over, balancing RTO and RPO, and choosing among four patterns—Active‑Standby, Active‑Active, Cold Standby, and Hot Standby—each with distinct synchronization, load‑balancing, and cost considerations for reliable system design.
The article explains various high‑availability solutions for stateful backend services, comparing cold backup, dual‑machine active/standby, same‑city active‑active, cross‑city active‑active, and cross‑city multi‑active approaches, and discusses their trade‑offs, implementation details, and real‑world examples from large internet companies.
