Amazon Elastic Compute Cloud (Amazon EC2) computing instances are only used as needed for testing. Unlike conventional backup methods, data is not backed up to tape. This simple and low cost DR approach backs up your data and applications from anywhere to the AWS cloud for use during recovery from a disaster. The following figure shows a spectrum for the four scenarios, arranged by how quickly a system can be available to users after a DR event. With multiple regions and Availability Zones (AZs), you can recover from disasters anywhere, any time. The AWS Cloud lets you back up, store, and recover IT systems in seconds by supporting popular DR approaches from simple backups to hot standby solutions that failover at a moment’s notice. Thousands of public sector customers, like St Luke’s Anglican School in Australia and the City of Asheville in North Carolina, rely on AWS to enable faster recovery of their on-premises IT systems without unnecessary hardware, power, bandwidth, cooling, space, and administration costs associated with managing duplicate data centers for DR. With the AWS cloud, you can rapidly recover mission-critical systems while optimizing your disaster recovery (DR) budget. Updated June 2021 with additional resources.ĭue to common hardware and software failures, human errors, and natural phenomena, disasters are inevitable, but IT infrastructure loss shouldn’t be.
