What is Multi-Regional Redundancy in AWS?

Amazon Web Services (AWS) provides a range of backend products that are used by developers to implement advanced networking features on smaller budgets. In a traditional development cycle, a software company would typically need a huge budget to purchase, install and maintain servers to host an application and provide backup for an application's data. With AWS, the physical servers used for hosting and maintaining an application are provided by Amazon, and many of the management tasks, including multi-regional redundancy, are handled by Amazon as well.

Why Multi-Regional?

As a redundancy strategy is implemented to provide support in the event that a disaster strikes a specific region, multi-regional redundancy uses multiple servers in specific regions to transfer connections if one is lost. The idea is that having multiple redundancies in a region allows for another server to pick right up where one leaves off if a natural disaster or other emergency strikes. These redundancies are all connected, and they can seamlessly transfer connections as needed based on current events.

Having an AWS disaster recovery multi region redundancy solution in place is also important in these situations. An AWS disaster recovery multi region redundancy solution can ensure that even in the worst of circumstances, data can be recovered should it be erased from servers due to the loss of one or more devices. Traditional disaster recovery solutions may not be able to work within the AWS framework, meaning your company needs to invest in a dedicated solution.

Keeping Customers Connected

The reason for having multi-regional redundancy and disaster recovery solutions is to provide application users with consistent performance no matter what happens. When you're dealing with large volumes of data, particularly when it is sensitive data, your company needs to be able to protect customer information. If information like billing history or stored credit card information is lost, your company may have a very hard time regaining this information, and that could affect your business's ability to provide services in the future.
