Outages are inevitable. As we’ve seen over the past few years, every major cloud vendor’s experienced at least one, and we can expect that they will again at some point in the future.

They could lose significant amounts of revenue as a result of actual outages as well as diminished user loyalty. In this article, I will share baseline perceptions and methods of cloud-based DR.
