AWS Availability Zones

AWS Availability Zones are interconnected data centers with independent power, networking, and facilities, designed to deliver continuous operations even during large-scale disruptions.

Key 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.

AWS 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.
