MinimumKey Characteristics
Isolation
Each AZ is physically separate with independent power, cooling, and networking infrastructure.
Connectivity
AZs are interconnected with high-bandwidth, low-latency networking.
Redundancy
Multiple AZs enable high-availability architectures and disaster recovery solutions.
Fault Tolerance
Independent failure domains protect applications from single location failures.
Global Availability Zone Distribution
Availability Zones are isolated locations within each AWS Region, connected through low-latency links. This distribution ensures high availability and fault tolerance for critical workloads across different geographic locations.
