Resilience in Amazon EC2 - Amazon Elastic Compute Cloud

Resilience in Amazon EC2

The AWS global infrastructure is built around AWS Regions and Availability Zones. Regions provide multiple physically separated and isolated Availability Zones, which are connected through low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.

For more information about AWS Regions and Availability Zones, see AWS Global Infrastructure.

In addition to the AWS global infrastructure, Amazon EC2 offers the following features to support your data resiliency:

  • Copying AMIs across Regions

  • Copying EBS snapshots across Regions

  • Automating EBS snapshots using Amazon Data Lifecycle Manager

  • Maintaining the health and availability of your fleet using Amazon EC2 Auto Scaling

  • Distributing incoming traffic across multiple instances in a single Availability Zone or multiple Availability Zones using Elastic Load Balancing
