VMware Validated Designs does not exclude Stretched Cluster in general

Working as an architect in the VMware space you will sooner or later come across the VMware Validated Designs (VVD). Just a few weeks ago the latest version 4.0 was released to make adjustments for vSphere 6.5. It can be found here:

VMware Validate Designs Documentation

The designs are a great source for building your own architectures or building architectures for customers. The incorporated component architectures are natively built for availability, reliability and scalability. These are exactly the main goals I try to put in the designs I create for customers. The VVDs show up a good practise for a detailed setup that can be used for several use cases like Private Cloud or VDI deployments. VMware Cloud Foundation also makes use of the VVDs for its implementations.

But apart from this I also like to treat them as a framework which gives me the chance to keep the setup supported by VMware but also adjust it to the customer needs and make it fit like a second skin based on customers requirements.

Across their history they mainly relied/rely on a two region concept with one primary and fail-over region. This is a quite common architecture for U.S. setups. In the European space and especially in Germany customers often stick their existing architectures based a two datacenters setup working as an active/active pair. If you see this also as a two region setup or you would aggregate this into one region like me, is up to you. I prefer one region because the datacenters are in a short distance because of their synchronous replication/mirroring and so they build up a logical domain because for their active/active style.  This is why I split the region down to two physical availability zones (AWS term) and one virtual across two datacenters. This does not need to be undestand now, it will get clearer in later chapter.

In my understanding the VVD framework needs some extension in regards to Stretched Clusters and this is why I like to set up a series which guides through a forked version of the VVDs I personally use for customer designs:

  1. General thoughts
  2. Additions/Changes to physical architecture
  3. Additions/Changes to virtual architecture
  4. Additions/Changes to cloud management architecture
  5. Additions/Changes to operations management architecture
  6. Additions/Changes to business continuity architecture

Stay tuned!
