A few weeks ago, Hany Michael released a blog post on his NSX lab network. Embedded within is one of the most brilliantly clear diagrams of a very complex situation I’ve ever seen. It takes a level of skill to achieve the clarity of this diagram. What hit me, though, is the sheer level of complexity that Hany conveys in this document and how that complexity is inherent to the SDDC. It’s easy to argue that the diagram shows the smallest possible instance of an SDDC (except it skims over the storage). Not too surprising, as it’s an SDDC lab. It’s inherently VMware focused, but it could be applied to Hyper-V or OpenStack easily. Each function in the diagram would still be necessary, although some would switch or merge. This article will be quite VMware focused for this reason.
