Making the right decision on where to place a workload is crucial; the wrong decision can result in performance issues, the cost of re-work and re-deployment, and inefficient use of available infrastructure.
Over-Licensing Software
Certain applications offer software licensing models for virtual infrastructure on a per-processor or per-core basis. In effect, this permits the licensing of an entire host, which enables an organization to run an unlimited amount of VMs requiring that certain application (such as Windows OS) on that host. This creates a significant opportunity, and by concentrating workloads requiring certain license types to certain environments and certain hosts, it can significantly reduce costs. Conversely, operating or planning environments without considering this factor can increase licensing costs significantly.
