Disaster Recovery Planning and the Cloud
We must remember that a disaster is an event or chain of events that results in a company’s inability to provide critical business functions for a period of time. It may also cause the company to move from using SOP(standard operating procedure) to employing its disaster recovery plan, potentially at another facility.
A business interruption is any event, whether planned or unplanned, that disrupts the normal course of operations—which, if not addressed within a predetermined amount of time, may turn into a disaster.
Although your cloud provider might be able to prevent major disasters from occurring, can it prevent business interruptions? And can these interruptions turn into a disaster?
One of the points I’d like to make is, “How can we SaaS-ify our apps?” SaaS is a dominant service within cloud computing. In my opinion, it’s the service we should be providing to our end-users, using our own private cloud, or even perhaps leveraging a public cloud—if we can ensure we can survive disasters and business interruptions. Remember, divorce is expensive in the cloud, just like in real life!
From a technologist point of view, I think Cloud Computing really means thinking in terms of redundancy—not performance, reliability, or availability.
Has there been an instance where you've had your business interrupted due to a 'disaster'? Did you have a DR plan? Did it include the Cloud? We'd love to know your experience.
