There has been a lot of buzz around using the cloud for disaster recovery lately, and with good reason -- it's a new and compelling approach to fast recovery. However, along with any hype comes a certain amount of confusion, so I set out to get some clarity on what cloud-based disaster recovery really is.
The core feature of any
cloud-based recovery is that ability to actually recover at the
providers' location using their cloud assets. Just copying data there is
not true recovery. I also realised that the term "cloud-based
disaster recovery" was too broad, and that actually solutions fall into
one of three categories:
Do-it-yourself (DIY): Using the public cloud to architect a custom fail-over solution using the agility and speed of the cloud.
DR-as-a-service (DRaaS): Pre-packaged services that provide a standard DR fail-over to a cloud environment that you can buy on a pay-per-use basis with varying rates based upon your recovery point objective (RPO) and recovery time objective (RTO). Data is either sent using backups or replication.
Cloud-to-cloud disaster recovery (C2C DR): The ability to fail-over infrastructure from one cloud data centre to another, either within a single vendor's environment or across multiple vendors.
Want to learn more about the ins-and-outs of cloud-based disaster
recovery? Forrester clients can check out a report I recently wrote on
the topic "An Infrastructure And Operations Pro's Guide To Cloud-Based Disaster Recovery Services"
or you can tune in to my BrightTALK webinar.
The BrightTALK webinar is actually a sneak peak of some of the information I'll be presenting this Spring at Forrester's Infrastructure & Operations Forum 2012 and Forrester's Infrastructure & Operations Forum EMEA 2012.
