HA – High Availability or HighER Availability?

HA – High Availability or HighER Availability?

I’ve been mulling over the need for HA. Yes, you read that correctly. Mulling over. When I hear discussions about what is does the typical (initial) response is that it protects virtual machines. That’s true, sort of. I believe it depends on how you perceive it functions in your own environment or deployments as to how you answer. In VMware terms the high availability feature offers resilience to guest virtual machines in the event the...
