Deployment Topologies

Overview

Deployment topology determines availability, latency, and disaster recovery capabilities. This section explores patterns from single-region high-availability to multi-region active-active systems.

Core Topologies

1. Single-Region Multi-Zone – Data center with multiple availability zones; high availability within one region.

2. Multi-Region Active-Active vs Active-Passive – Geographic redundancy with trade-offs in consistency, latency, and operational complexity.

3. Disaster Recovery Patterns – Backup, restore, RPO/RTO, and failover strategies for business continuity.

📄️ Single Region, Multi-Zone Deployments

Deploy across multiple availability zones within a single region for high availability, fault tolerance, and synchronous data consistency without multi-region latency penalties.

📄️ Multi-Region Active-Active vs Active-Passive

Geographic redundancy patterns, consistency trade-offs, and traffic routing

📄️ Disaster Recovery Patterns

Backup strategies, RPO/RTO, PITR, and failover testing for business continuity
