ESXi consists of 3 components: VM , Virtualization layer and virtual network layer.
by adding more layers this will increase the latency. so how did you overcome this problem?

in Network legacy E1s System and STM-N is more reliable than IPs Networks.
in 2000 the IP technology has crashed the TDM transmission although TDM is more reliable. but IP networks are flexible and scale-able.
so do you think that VM will overcome the dedicated HW and become the next future technology. or will it be dead as WiMAX?

A step by step guide having screenshots are always very useful. Thanks

It’s Not Cloud Computing
Cloud computing is not the same thing as virtualization; rather, it’s something you can do using virtualization. Cloud computing describes the delivery of shared computing resources (software and/or data) on demand through the Internet. Whether or not you are in the cloud, you can start by virtualizing your servers and then move to cloud computing for even more agility and increased self-service.
