Advanced Design VMware Cloud Management & Automation 2021 Exam (3V0-32.21) Study Links

I took the Advanced Design VMware Cloud Management & Automation 2021 Exam recently and these are the study links I used:

VCDX – Modern Solutions

In the last month I have been involved in a few VCDX mocks. One of the things I have been explaining to VCDX candidates is the importance of being knowledgeable about modern infrastructure design and being able to articulate the business value.

List of articles in my VCDX Deep-Dive series (more than 90 posts)

The way the VCDX blueprints are written, you are encouraged to design a “Build Your Own” solution, which is the antithesis of cloud and the SDDC. Which leads to VCDX candidates following the “BYO” route without considering and understanding how automation, cloud and the self-driving SDDC functions and adds value to a customer.

Am I saying you need to be an expert in VMware Cloud Foundation and VMware Cloud? No, but I am suggesting that you need to be aware of it and be able to describe how it works and articulate the business value realized.

What “modern” VMware solutions am I referring to? Solutions such as the entire suite in VMware Cloud (vRA Cloud, Log Insight Cloud, Cloud Health, Tanzu, etc.), VMware Cloud Foundation (including VCF on VxRail), VMware Cloud on AWS (and all other hyperscaler VMware variants: Oracle, Microsoft, IBM, GCP, etc.), VMware vRealize Suite Lifecycle Manager, Horizon 7 on VMC on AWS/Azure, etc. And understand how the VMware Validated Design (VVD) framework relates to these solutions.

In my opinion, here are some suggestions on how you can weave this into your VCDX submission and the panel defense:

VCDX – Your Voice

As you go through the VCDX process, you will get a lot of feedback from your study group and the VCDX mentors you have mock sessions with. That feedback is a gift, you need it to evolve and grow the skills to be successful as a VCDX and an Architect. The trick is to take that feedback and incorporate it into your style of talking and presenting and make it yours. This includes filtering that advice and discovering what is best for you and what is not. I think of it as finding your “Voice”, the thing that makes you unique and is at the core of your identity as a person. And we are all different, what works for me, may not work for you.

Finding your voice takes time and effort. And making major changes to how you do things at one time should be avoided. You want to improve your game one step at a time. If a minor change works, keep it, if not, discard it and then move onto the next improvement.

During the mocks I was involved with in the past month, one of the candidates was asking me about how much information to share during the defense to reduce the “attack surface”. On this subject I have changed my mind over the years. My current thinking: if you know a particular subject or technology in-depth, you should talk about it and showcase your knowledge to the VCDX panel. Let them ask all the questions they want and if you do not know, then say so; you are there to demonstrate your skills and knowledge. For me personally, I have always found the process of “stepping around” certain subjects interrupts and impedes my flow, so it is better to just go for it and let the chips fall where they may.

NPX – The Right Hypervisor

I was talking to some potential NPX candidates the other day and I was describing the strategy for selecting the correct hypervisors for the NPX Design Review (NDR). Nutanix is a hypervisor agnostic platform, you can use ESXi, Hyper-V, AHV (KVM-base) or Citrix (for Citrix VDI only). The NPX candidate needs to choose two hypervisors as part of the NPX application form, one hypervisor for the NPX design submission and the second hypervisor for the NDR design scenario and the NDR hands-on scenario (troubleshooting). You cannot use the same hypervisor for both parts of the NDR (with the exception of a multi-hypervisor design submission, then you can choose what you want – thanks to Artur for this clarification).

The NPX Link-O-Rama is a great resource for all things NPX, including this applicable list of articles in my VCDX Deep-Dive series (more than 90 posts).

The Nutanix Acropolis Hypervisor (AHV) has come a long way in the 5-years since it was released, including the Nutanix hybrid cloud products that have become available during that time (e.g. Nutanix Era, Karbon, Objects, Clusters, Calm, Flow, Files, Leap, Beam, etc.). With that thought in mind, my recommendation to anyone considering the NPX journey would use AHV as the hypervisor of choice for the design submission. The reason being, using a third party hypervisor with Nutanix is incredibly complicated and you have to worry about integrating and customizing the technologies of two vendors just to get the on-site SDDC functioning correctly.

For example, if you selected VMware vSphere as the hypervisor, consider the complexity of the design to address the advanced ESXi settings, the deployment of vCenter Server (Nutanix Foundation does not automate this, only the ESXi/AOS imaging process), the customization of vCenter Server, the use of NSX-T for micro-segmentation, the advanced operational procedures to capture that complexity, etc.

With Nutanix AHV, you do not have this problem, Foundation images the nodes with Prism included as an AOS service, Prism Central is a multi-cluster manager and advanced operations manager, Nutanix Flow provides micro-segmentation (as a Prism Central service) which AHV natively supports and so forth. Using this strategy would significantly reduce the complexity of the design and decrease the number of hours needed creating the submission documents. Which makes sense, because Nutanix is all about customer delight and simplicity.

If you follow this strategy, you still need to demonstrate mastery of the second 3rd party hypervisor during the NDR design and hands-on scenarios, however you only need to talk about it, not write about it; which is a big difference.

Book 4 of the IT Architect Series announced

The IT Architect Series is getting ready to release their 4th book in the series titled “Stories from the Field – Horror stories and lessons learned from IT Architects, Operations and Project Management.” This effort was led by Matthew Wood, John Arrasjid and Mark Gabryjelski with a total of 34 stories from 34 contributors. The contributor list is a who’s who of vCommunity, vExpert, Nutanix NTC, VCDX, NPX and DECM-EA certified individuals. If you want to learn from the mistakes of the best, this book is for you.

Each story is tagged with Topic Codes that assist the reader in locating their areas of interest. The chapters are consistently structured to explain the What, How, Why, etc. for ease of reading.

The impressive cover art was designed by Ioannis Dangerous Age.

When this book is released, you will be able to buy it as an eBook or printed copy. Keep on eye on the IT Architect Series site for updates.

Not Quite Right Infrastructure Platforms

Have you worked with infrastructure platforms that were not quite right? Niggling little annoyances that do not impact delivering services but add that extra effort to get your job done? Things like self-signed SSL certificates, local user accounts and naming standards that make no sense.

These things translate into technical debt, that additional friction that makes it harder for an operations team to do their jobs effectively. When we add the time lost over the years the solution runs for, this amounts to hundreds of man-hours. The amount of effort to fix these things after an infrastructure platform is in production is so much harder than taking care of it when the platform was being built.

My message to the delivery architects and delivery engineers out there, as you are deploying your solutions, ensure you are making your infrastructure platforms as easy to own and operate as possible. Considerations such as:

  • SSL certificates from the company Certificate Authority: nothing screams “amateur” more than having to accept self-signed certificates in a Web browser. It only takes a little more effort to complete the CSR request and CER import process and this will save future operators years of mouse clicks to “Add Exception” for “Invalid Security Certificate” messages.
  • All infrastructure Syslog endpoints should point to a central Syslog server: Syslogs that are cached locally are of no use to you when that device is down for the count. A centralized syslog server gives you a time machine into holistically working out what happened with your entire infrastructure for a past event. Open Source Syslog servers like syslog-ng are free. If you are running vSphere, get licensed for vRealize Log Insight, the plug-ins for vSphere are built into the product.
  • All infrastructure management interfaces are integrated with AD and use RBAC via AD groups: Maintaining a bunch of local accounts with separate passwords for the different components of an infrastructure solution make no sense. Configure SSO for the entire solution, so that the operators can login using their domain credentials. Use AD groups for role-based access control, that way when a new employee joins the team, they are placed into the same AD group as their colleagues and they immediately have the access they need.
  • Common naming standard that is human readable: another pet peeve of mine, use a naming standard that applies to every facet of the infrastructure solution (App, Compute, Network, Storage, DR, Data Protection, Cloud, etc.). One that someone can read and instantly understand what they are looking at and does not require them to open a spreadsheet to decode an obscure alpha-numeric string.
  • Day-2 Lifecycle Management: most platforms now have some type of lifecycle management that allows the automated deployment of patches and updates. Design, build and test them as part of the solution. Do not leave this for the operations team to take care of after the fact. Things such as vRealize Suite Lifecycle Manager, vSphere Update Manager, Nutanix Lifecycle Manager. If you are designing a VMware SDDC, look at VCF with vSAN-Ready Nodes and VCF on VxRail or better yet, consider VMC on AWS. If you are going down the Nutanix route, take a look at Nutanix with AHV.

If you have other “Not Quite Right” examples, feel free to add a comment. Thanks for reading this far!
