There was a time when Microsoft prohibited running Microsoft Exchange inside virtual environments due to the unknown ways by which the hypervisor-based environment could negatively impact the operation of Exchange. However, those days are long gone as Exchange Server 2013 and Exchange Server 2016 deployments are increasingly virtualized. Virtual environments allow Exchange professionals to increase server resources, Exchange Server protection and migration or recovery tasks in the event of problems. This acceptance of Exchange into the world of virtualization has taken place as a result of massive improvements in modern hypervisors coupled with massive improvements in Microsoft Exchange. Now, organizations using Exchange can easily leverage their hypervisor investments and implement Exchange just like any other application in the environment.
This leading to prospective employers wanting Exchange administrators who know Microsoft Hyper-V or VMware vSphere to support virtualized deployments. Even if a prospective employer's Exchange deployment isn't yet virtualized, finding a candidate with virtualization expertise can be an essential part of an Exchange admin job description. Something to consider then selecting a training partner for your organization.
