Redundancy in the Cloud

Somehow, a perception exists that a cloud provides a certain level of redundancy by default. However, make no mistake. Redundancy is not inherent. Admittedly, individual hardware and software components have some redundancy built in. However, those capabilities do not eliminate the need for a redundant cloud any more than safe cars eliminate the need for speed limits, traffic lights, divided highways and the rules-of-the-road. For many cloud providers, especially consumer cloud providers, the only redundancy offered is to make physical copies of the data—and many customers do not use even that minimal level of recovery.  These clouds were not built with redundancy in mind.  They lack the au … Read more

Business Continuity in the Cloud

Business continuity focuses on the resiliency, restoration, disaster recovery and security needed to keep your system operating, performing, secure and, if an incident should occur, recoverable. Many cloud vendors have little experience with business continuity, preferring instead to offer consumer cloud services to clients that provide their own back-up procedures, intrusion protection, vulnerability alerts, firewalls, software upgrades and disaster recovery planning/testing. Resiliency is the key Without strong resiliency, redundancy and failover capabilities at each layer of the cloud stack, the failure of one component can cause the  failure, in short order, of many subsequent … Read more
