Understanding Availability Zones (AZs): An Availability Zone is a distinct location within an AWS region that is engineered to be isolated from failures in other AZs.
Characteristics of Availability Zones:
Data Centers: Each AZ consists of one or more discrete data centers with redundant power, networking, and connectivity.
High Availability: AZs are designed for high availability, providing low-latency network connections to other zones in the same region.
Fault Isolation: They provide fault isolation and are used to deploy applications and services to ensure high availability and reliability.
Use Cases for Availability Zones:
Multi-AZ Deployments: For services like RDS, deploying in multiple AZs ensures fault tolerance.
Disaster Recovery: Setting up resources in multiple AZs helps in quick recovery from failures.
Load Balancing: Distributing traffic across AZs using Elastic Load Balancing ensures optimal performance and availability.
