Cloud deployment architectures define how and where cloud workloads are distributed across geographic regions, availability zones, and infrastructure types to meet requirements for availability, latency, compliance, and disaster recovery. These architectures range from simple single-region deployments to complex geo-distributed systems spanning multiple clouds and edge locations. Understanding the trade-offs between cost, complexity, recovery objectives, and data residency is critical—each architecture pattern addresses different failure domains, consistency requirements, and user proximity needs, and choosing the wrong pattern can result in unnecessary downtime, regulatory violations, or budget overruns.
