Here is an interesting info from InfoQ: VMware Has Launched vSphere, the OS of the Cloud.
The concept they are focused on is the internal or private cloud:
You can take a relatively small configuration of servers, just a few servers, and put those on a scheduled maintenance basis, install everything, and if something breaks you don’t call somebody right away, you wait for your weekly or monthly visit and they will come in and replace it, because our software will self heal and keep running.
We still don’t manage datacenters effectively, we surely struggle with virtualization … is the private cloud the solution? Tell me what you think!
