Today we had a very interesting presentation from Citrix. At one point the discussion was about the Citrix’s definition of High Availability.

I really can imagine that this is getting a confusing discussion. VMware says: HA is to resolve a single host failure. Citrix however also calls live migration a form of HA.

I can’t argue with that but to keep the discussions and comparisons clear it is essential to specify what you define as HA. I think both are right, but the trouble is that, when comparing products, people think they have a solution for hardware failure, but instead they can do a live migration.

I hopefully that in the future both parties start using the same names for the same options, or at least explain what their option is.
