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.
1Cloud failure prep-
Prepare for a cloud outage
Enterprises that move data to the public cloud don't often think availability or disaster recovery is their responsibility, especially with large cloud providers like Amazon Web Services. But what happens when that public cloud fails? We look at how some infamous cloud outages affected enterprises and give advice on how to prep for this in the future.

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.

3DRaaS and other options-
DRaaS 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.
When it comes to pricing out a cloud disaster recovery plan, look beyond simple recovery times and to RTO and RPO. Continue Reading
