Cloud and disaster recovery: Load-balanced data centers are not a perfect solution

Gregory Machler | Jan. 11, 2012
A growing trend in the disaster recovery arena for cloud providers is the use of load-balanced data centers instead of hot-cold data centers. Companies are deploying private clouds that are load balanced between their datacenters to take care of disaster needs.

In conclusion, corporations are addressing disaster recovery concerns by deploying applications in load balanced architectures. But this doesn't protect against human error, particularly configuration errors. Corporations may turn to certified components like specific virtual machines or load balancers to avoid some of the disasters due to an untested configuration or a lack of versioning of configuration metadata. Configuration metadata needs to be stored in a centralized manner and versioned so that the application can fall back to a trusted configuration if errors occur.
