DR (disaster recovery) is one of those topics that is addressed each time applications or a data set is placed into production, but often it’s just a checkmark. Deploying applications to public clouds should be no different. However, some confusion has arisen. I’ve looked into this and found three cloud-based disaster recovery myths that seem to be derailing enterprises as they move to the cloud.
Myth 1: DR is not needed because it’s already built in to public clouds.
The confusion here is that some basic DR features are systemic to public cloud providers; they have backup systems in case of hardware failure or actual disasters. But their systems don’t consider the specific DR needs of tenant-owned workloads.
