AWS Elastic Disaster Recovery
Explore AWS Elastic Disaster Recovery to understand how it enables secure, continuous data replication and quick recovery of on-premises or cloud data. Learn to minimize downtime through automated failover, validate recovery plans with data drills, and save costs using economical computing resources. This lesson equips you to manage disaster recovery efficiently using AWS services.
We'll cover the following...
Amazon Elastic Disaster Recovery (DRS) is a managed service provided by AWS for reliable backup and restoration of on-premises and on-cloud storage. It enables quick data recovery and minimizes application downtime caused by data loss.
Elastic Disaster recovery allows users to configure secure and continuous replication to a staging area subnet in the selected region. The staging area is designed to utilize economical storage options and fewer computing resources. The architecture of Elastic Disaster Recovery is optimized to reduce the upfront costs required for setting up replication and storing the data. It uses t3.small, the most economical compute instance for computation.
How DRS works
Elastic Disaster Recovery has two main functions: Data replication and recovery. It replicates the data on EBS volumes and restores them when required. Let’s learn more about the workings in detail:
