Why you need a AWS cross region disaster recovery plan

When it comes to developing a disaster recovery (DR) plan for your business, there isn’t a one-size-fits-all approach. However, despite the many variables that go into forming a specific DR plan, almost any business will benefit from the geographic diversity offered through AWS cross-region disaster recovery.

In the following article, we’ll explain why AWS cross-region disaster recovery should be part of most DR plans, and highlight a few non-DR benefits related to cross-regional storage. We’ll also explain how CloudRanger can help save time and money by simplifying your company’s cross-regional backup and disaster recovery process.

The Importance Of An AWS Cross-Region Disaster Recovery Plan

One of the most important elements of any disaster recovery plan is creating a backup strategy for your business data. So figuring out what data to backup and how often to do so is an obvious place to start. But an equally an important question to answer is where your business’s data backups should be kept.

As we’ve previously discussed, the entire point of DR-related backups is to ensure business continuity in the face of a natural or man-made disaster. As such, storing your backups in close geographic proximity to your normal production environment leaves all of your data exposed to the same threats.

For example, as I write this article, a major hurricane is threatening the East Coast of the United States. Obviously, no one knows exactly what will happen. But a worst-case scenario would result in power outages across the region that could take weeks to repair.

Hypothetically, if your business was located in the path of the storm, where would you rather have your backup data: in Virginia, a state that is also in the path of the hurricane, or in Oregon, which located safely on the opposite side of the continent?

Clearly, distance plays a key role in keeping your business online in the event of a disaster. And with AWS cross-region disaster recovery, you have the ability to store your backups in numerous locations around the world, which makes putting distance between you and your important data easier than ever. Even if an entire AWS region were to be knocked offline, your business could continue to operate with little-to-no disruption as long as a proper, geographically-diverse recovery plan is in place.

Other Benefits Of Cross-Region Backups

Aside from the obvious DR-related benefits of cross-regional backups, there are several other reasons to add geographic diversity to the mix. For example, as tech-writer Adrian Hornsby points out, having your content stored in close proximity to your end users will help diminish the revenue-killing latency issues that can result from distance. Depending on your company’s needs and budget, a “hot standby” or “warm standby” disaster-recovery method could be employed using multiple regions. This would completely replicate your data across multiple locations, and route users to the closest option based on their location. And should disaster strike, all traffic would simply be rerouted to whichever region(s) remained online.

Another non-DR benefit that comes with cross-regional storage is the ability to simply and easily transfer data between multiple countries/jurisdictions in order to comply with local laws and regulations. For example, many national governments are creating stricter regulations regarding how and where user data is stored. As new regulations come into effect, a business can be left scrambling to comply. But with an AWS cross-regional storage plan in place, data can easily be transferred across the globe in order to adhere to (or avoid) local regulations.

About CloudRanger

While the benefits of AWS cross-region disaster recovery are clear, the platform’s somewhat confusing interface can complicate the process, especially for non-IT/DevOps professionals. Luckily, CloudRanger makes things much simpler with a straightforward, easy-to-use dashboard. With just a few clicks, even the most novice users can automate a cross-regional backup process, or implement a recovery plan should a disaster strike. And thanks to CloudRanger, all this can be done without the need for in-house scripting. Download our free whitepaper of How to add disaster recovery to your AWS environment to find out more.
