Self-service Disaster Recovery for AWS environments

ADR plans

The Amazon Web Services (AWS) shared responsibility model outlines the differentiation of Security ‘of’ the cloud with AWS and Security ‘in’ the Cloud with the customer. Workloads that are migrated or created in AWS are not implicitly protected with Disaster Recovery (DR) capabilities. 

“Systems, sites, and networks can fail no matter where they are located or who is managing them. Mission-critical service availability and protection of corporate data are essential no matter where services reside.” 

“Cloud services are not based on traditional enterprise architectures and management. IT departments no longer have end-to-end control of the environment.”

    – Gartner report on DR implementation

Enterprises need to be prepared for failures to their cloud infrastructure due to user errors, malicious & insider threat, operational mishaps or site outages. In this blog, we will explain how with Druva CloudRanger you can keep your AWS data safe and easily recoverable from any region-specific or account-specific outage.

Disaster Recovery for your AWS environments
You may have recently read that on Labor Day weekend in the US, AWS had an issue with customer data in US-East where a power outage caused a major issue for Amazon EC2 instances and EBS volumes in US-East-1 – reported in this article by The Register. This highlights the risks of not replicating your Amazon EBS snapshots and Amazon Machine Images (AMIs) across availability zones, regions or accounts within AWS.

While considering a disaster recovery (DR) plan for their various AWS environments, enterprises should look at the following aspects for maintaining business continuity in a potential disaster situation:

  • Flexibility & Availability – While AWS offers 20+ regions, 200+instance types and 100+ services, not all regions have the same number of availability zones or support all instance types. As an example, N. Virginia has 6 Availability Zones (AZ’s) while Ohio has 3 AZ’s
  • Cost considerations – AWS subscription model requires you to only pay for the services utilized but there are transfer (egress) charges when data is moved out of a region. Likewise not all regions cost the same.
  • Compliance and controls – From a DR perspective, it is important to consider data residency requirements and operational issues due to incorrect security settings in your DR sites. AWS IAM roles are account specific and KMS keys used for data encryption are region-specific.
So, what should your cloud DR solution offer?

A successful cloud DR solution should make it simple to set up and update DR plans with automation. It should support availing the merits of AWS cloud.

The Druva CloudRanger DR solution for native AWS workloads enables organizations to have a self-service DRaaS approach by making Disaster Recovery plans simple to set up, keeping them current, tested and cost-optimized for their AWS environments.

Here is how you can setup DR plans with Druva CloudRanger
