vSphere 6, VSAN & NSX 6.2 Homelab In The Public Cloud

Over the last few years the suite of products which VMware offer has grown its made it less practical to obtain and run enough hardware for a home learning lab.

As the VMware product portfolio is expanding to more of a suite of products under the banner Software-Defined Data Centre (SDDC) interoperability becomes more important and the best practice settings, testing and supportability becomes more complex.
