AWS Disaster Recovery Best Practices In the modern business environment, any business can be subject to disruption. Any activity that can negatively affect a company’s business continuity could be termed a disaster. It is crucial, therefore, for a company to invest time and resources into defining all possible risks and being able to prevent them – or at least act accordingly to mitigate their negative impact. Thus, creating a thorough disaster recovery (DR) plan for your infrastructure becomes a matter of the highest priority. In this blog post, we cover the best practices for disaster recovery planning in a cloud environment. Benefits of Using AWS for Disaster Recovery AWS is a dynamic product which offers a wide range of services including database storage, compute power, content delivery, and other distinct features. Moreover, AWS can help quickly restore your business operations running on virtual machines (instances) in case of disaster. The AWS platform allows you to promptly moderate and recover your resources during a disaster. Keeping business-critical data in the AWS cloud also removes the necessity for a secondary physical storage system, which generally entails significant costs. In fact, your data can be stored in multiple AWS regions across the world, securely and reliably. As a part of its disaster recovery functionality, AWS enables you to run and test a DR solution to check for any deficiencies. Then, you can use AWS CloudFormation templates to define the most efficient DR practices and save them in an Amazon Virtual Private Cloud for further use. Disaster Recovery Scenarios with AWS The choice among AWS DR strategies depends on your business’s priorities. Various combinations are possible to accommodate the specific needs of your virtual infrastructure. Backup and restore. Business-critical data can be backed up and sent to an off-site location such as Amazon S3, where it is well protected and can be rapidly restored as needed. Amazon S3’s web user interface makes it accessible from anywhere. You can copy data directly to Amazon S3, or you can create backups and store them in the cloud. Pilot light. This DR scenario lets you have a small version of a virtual environment in the cloud, always keeping it running and up to date. You can rapidly recover and launch the most critical components of your AWS-based infrastructure. Services such as Amazon Machine Images (AMIs) and Amazon EBS snapshots are used. The pilot light method is more convenient than the back-up-and-restore strategy as it significantly reduces the time spent on recovery. Warm standby. In this DR scenario, a scaled-down version of your production infrastructure is always running in the cloud. During a DR event, it can be rapidly scaled up to minimize downtime and restore critical operations and workloads. Multi-site deployment (“hot standby”). This method entails replicating business-critical data and the core components of your infrastructure and distributing them across several locations. All of these sites are active; they share the traffic and workloads. If a disaster affects one of the locations, you still have an intact system ready to operate in full production mode. Amazon EC2 Auto Scaling is used to run this process. With hot standby, minimal Recovery Time Objective (RTO) and Recovery Point Objective (RPO) are achieved. However, running several virtual systems at once can be quite costly. The following features should also be mentioned in the context of Disaster Recovery: Replication. To ensure high availability, Cross-Region Replication can be implemented. Here, critical data and system components are replicated to any other AWS region that you choose. If any changes are made in the primary database, data can be updated either instantly (synchronous replication) or with a small delay (asynchronous replication). These two types of replication serve different business needs. Failback. During the DR process, the workload of the affected instance is moved to the target site and the replica instance is powered on (failover). Once the primary site is restored, you can recover the original instance. To save all the changes in data that were executed in the DR instance since failover, you need to reverse the flow of data replication back to the primary site (failback). Multiple AWS regions. Each AWS region is a separate and independent area intended to store either instances or data. For successful DR, you might choose to store data in two or more AWS regions to mitigate the impact of extremely large-scale disasters.
