From physics into the virtual world
As part of the data center virtualization, there are various courses that deal with the current platform. On the one hand there is the VMware vSphere ICM (Install Configure Manage) which builds up basic knowledge and starts with the individual ESXi hosts and the vCenter. In addition to the introduction to the Software Defined Data Center (SDDC), topics such as storage, virtual networks with dependency on physical networks and the handling of virtual machines are considered. High availability and reliability are not neglected.
As part of the vSphere courses, there are also individual update courses such as What's New or courses on the virtualization of containers (VMware vSphere with Tanzu).
