"Availability" can be achieved in two ways = Resilience and Recoverability.

  • Recoverability are the myriad methods of rapidly restoring functionality through the use of technologies like near-instantaneous VM restoration or leveraging snapshots.

The modern data center by definition should be highly virtualized must also be both resilient and recoverable, in order to be dependable enough to then deliver the other promises of modern IT around agility, flexibility, etc. With that in mind, here is a short video of what folks should be looking for to fulfill the recoverability requirements of highly virtualized environments, thus helping to achieve the availability of the modern data center:

As always, thanks for watching.
