Examine DR in the cloud from all angles

Last updated:May 2014

Editor's note

The public cloud seems like a natural fit for enterprises looking for cost-effective disaster recovery. It can enable faster recovery times in the event of an outage; and by spreading data across multiple availability sites, enterprises usually can rest assured their data is replicated and secure. But can they, really?

Even though DR in the cloud offers several advantages and is now more accessible to companies with budgets of all sizes, it's not without issues. And while cloud outages involving large service providers like Amazon Web Services are less prevalent than they used to be, outages can -- and will -- happen. Enterprises that simply believe their disaster recovery plan is sound, without testing it, could be in for a big surprise when they lose data during an unplanned event.

This guide looks at DR in the cloud from all angles -- from previous AWS outages and the companies affected, to tips on preventing an outage, implementing a proper DR strategy and testing those strategies. We'll also examine the burgeoning market of disaster recovery as a service (DRaaS) and how it could help to bring cloud-based disaster recovery to the masses.

1Implement a cloud DR strategy

There's more than one way to approach cloud-based disaster recovery, whether it involves putting data into public cloud, building a hybrid cloud, using cloud bursting methods or relying on a third-party tool. When considering DR in the cloud, it's important to mimic an on-premises setup and test your methods.

2DRaaS offers cost-effective alternative

Disaster recovery options are expanding. Even though disaster recovery is essential for most companies, large enterprises often ignored best practices because of high DR costs. Disaster recovery as a service brings cloud-based DR to companies of all sizes and all budgets. And as large public cloud providers like AWS prove availability with each passing year, more companies are willing to trust them with their data.
