Cloud Disaster Recovery Amazon Elastic DR


Disaster can strike anytime, leaving businesses vulnerable to data loss and operational disruptions. Organizations need a robust disaster recovery (DR) Strategy to mitigate the impact of such events. Traditional on-premises disaster recovery solutions have long been relied upon, but new possibilities have emerged with the advent of cloud computing. This article explores the advantages of cloud disaster recovery over on-premises alternatives and introduces Amazon Elastic Disaster Recovery as a cutting-edge solution.

AWS Elastic Disaster Recovery (AWS DRS) minimizes downtime and data loss with fast, reliable recovery of on-premises and cloud-based applications using affordable storage, minimal compute, and point-in-time recovery.

How it works

Setting up AWS Elastic Disaster Recovery on your source servers is important to ensure secure data replication. This will replicate your data to a staging area subnet in the AWS Region of your choice, using affordable storage and minimal compute resources to reduce costs.

You can confirm implementation by performing non-disruptive tests. Regularly monitor replication and conduct non-disruptive recovery and failback drills to stay prepared. If you need to recover applications, you can launch recovery instances on AWS within a few minutes using the latest server state or a previous point. Once your applications run on AWS, you can keep them there or replicate data back to your primary site after resolving the issue. You can return to your primary site.

Instantaneous Recovery

One of the key differentiators between on-premises and cloud-based disaster recovery is the speed at which recovery can be achieved. On-premises solutions often require additional setup, configuration, and testing time, resulting in longer recovery time objectives (RTOs).

In contrast, cloud-based disaster recovery offers instantaneous recovery capabilities, enabling businesses to quickly restore their systems and minimize downtime.

Replicating to the Cloud

Cloud disaster recovery relies on replicating critical data and applications to the cloud, ensuring their availability during a disaster. By leveraging cloud storage and computing resources, businesses can create redundant copies of their systems and data in geographically diverse locations. This approach minimizes the risk of data loss and provides an added layer of protection against localized disasters.

Emergency FallBack

While cloud disaster recovery offers numerous benefits, some organizations prefer an emergency fallback option to on-premises infrastructure. This hybrid approach seamlessly transitions between the cloud and on-premises environments, providing flexibility and control. Amazon Elastic Disaster facilitates this Hybrid model, enabling businesses to orchestrate failover and failback processes smoothly.

The Cost of AWS Disaster Recovery

Disaster recovery site setup can be expensive for businesses of different sizes. For a small business with 50 desktops and less than a dozen servers, the average cost could be as high as $200,000. The cost can run in millions for larger companies with hundreds of servers and thousands of desktops/laptops. However, with cloud-based DR solutions, these costs can be avoided altogether. Amazon Disaster Recovery is based on the pay-as-you-go model.
