Disasters can happen at any time. Whether it’s a hardware or software failure, network outage, or power outage, you have to stay prepared.
With AWS Backup and AWS Disaster Recovery, you can reduce the effects of these disasters and save valuable time and money in the process.
What Is AWS Disaster Recovery?
AWS Disaster Recovery refers to the resources you can launch on Amazon Web Services (AWS) in the event of a disaster. These resources ensure business continuity and reduce the overall impact on your data, your system, and your business operations.
It’s important to invest time and resources into planning and preparing for disaster recovery (DR) if there’s a high cost associated with a potential outage. You also need to ensure that your Cloud infrastructure is configured and correctly maintained so that it can support any anticipated capacity requirements during a disaster.
With AWS, you can quickly scale up your infrastructure on an as-needed, pay-as-you-go basis. Not only does this allow you to change and optimize resources during a DR event, but it also saves costs.
Backing Up Your Data On AWS
Traditional environments often require you to back up your data to tape and send it off-site regularly. This can lead to prolonged recovery times in the event of a disruption or disaster.
The best place to store your critical data is Amazon S3. Once transferred, you can access your data from any location, at any time.
There are also several commercial and open-source backup solutions that integrate with Amazon S3. For example, you can use AWS Import/Export to transfer large data sets or use Amazon Glacier as a low-cost alternative to Amazon S3 storage.
You can even combine Amazon Glacier and Amazon S3 to produce a tiered backup solution and use AWS Storage Gateway to copy snapshots of your on-premises data volumes into Amazon S3 for backup.
In the event of disaster or disruption, you can restore the cache volumes of your on-premise data to a second site running a storage cache gateway or to Amazon EC2.
Types of DR Approaches and What They Mean
There are three main types of approaches that you can take when recovering your data on AWS. By using one of these methods, you can ensure that your system will be available to users shortly after a DR event.
The first approach is known as pilot light. This term describes a DR scenario where the minimal version of an environment is always running in the Cloud.
You maintain a pilot light in your Cloud environment by configuring and running the most critical core elements of your system in AWS. You can then provision a full-scale production environment around the critical core in the event that you need to recover your data.
The term warm standby refers to a DR scenario where a scaled-down version of a fully functional environment is always running in the Cloud. A warm standby offers a faster recovery time than pilot setup. With warm standby, you can select which business-critical services you want to keep running in the background and then run these systems on a minimum-sized fleet of AWS EC2 instances on the smallest sizes possible.
Although this solution can’t handle a full production load, you can use it for non-production work such as QA, testing, and internal use.
In the event of a disaster, you can use the load balancer in AWS to quickly scale up the system to handle the production load, and resize the small capacity servers to run on larger AWS EC2 instance types.
A multi-site solution runs in AWS and on your existing on-site infrastructure, in an active configuration.
In the event of a disaster, you can use Amazon Route 53 to adjust DNS weighting and send all traffic from your on-site infrastructure to the AWS servers. You’ll then be able to use Amazon Auto Scaling to quickly scale the capacity on AWS to handle the full production load.
