Virtualization is the process of dividing a physical server to run more workloads and increase efficiency of the physical hardware. If you decide to consolidate the workloads of 20 physical servers onto a single physical server running virtualization, what are the affects of that process? The result of this consolidation is that 20 physical servers, which used to have their own dedicated I/O for CPU, memory, disk and network, are now running on a single server where these 20 workloads are now sharing I/O for CPU, memory, disk and network. Numerous potential bottlenecks have just been created. The good news is that modern server hardware is very fast and there are many techniques to help mitigate these bottlenecks. But, the key to a successful virtualization experience is to understand and alleviate these bottlenecks.
