Right now an average US corporation has about 7% of its Datacenter virtualized. As organizations continue to virtualize servers they will face 3 new management challenges:
1. Explosion in the number of virtual servers. User have already figured out just how easy it is for IT to create new virtual servers. The number of requests for new virtual servers will continue to skyrocket
2. Sharing of resources: memory, cpu, storage and network . In the traditional data center where one application server was dedicated to one application, no sharing of resources took place. That's not the case anymore in the virtualized datacenter
3. Servers have grown "legs". In the traditional datacenter we did not need to worry about servers moving around the network from one location to another. Now we do.
In the next post I will explore how VMWARE administrators can address the 3 new challenges
