VCDX #: 007

 

How did you get into using VMware?

I guess like many people… we were looking for a way to consolidate servers as we were growing out of our datacenter. Especially cooling was a huge problem for us so we needed to drastically lower the amount of iron in our datacenter. We explored several options but VMware was the only enterprise solution at that point. It proved to be the right decision, and that is also what was a huge change of direction in my career. Cause I changed from being a Windows admin to focusing purely on the virtual layer.

 

What made you decide to do the VCDX?

Well I worked for VMware already at that time. I was invited to take two early beta exams for VI3, which are now known as VCAP-DCA and DCD. Our group were literally the first group to take those exams. After about 6 months of waiting I finally found out that I passed those exams. When I was told I could do the VCDX Defense Panel I figured why not. Back then, and I was the first to actually take the exam (together with Richard Damoser who was in the room next to me), the process was slightly different though… You could say the early group did the beta defense.

 

How long did it take you to complete the whole VCDX journey?

From those beta exams to the defense itself probably 9 months in total. Funny thing is that in my case I heard 10 days before the defences were scheduled that I got a slot. Because I did not anticipated on it I didn’t have my docs ready. Although I heard it 10 days before, I only really had 4 days to complete the design as the panel of course needed to review and prep as well… on top of that I had a holiday with the family scheduled. So every night when my kids were in bed I was typing like a mad man. I guess I work best when under extreme pressure as the docs were accepted and the outcome of the defense was a pass 🙂

 

What advice would you give to people thinking of pursuing the VCDX accreditation?

Don’t just talk about it, DO IT! If you want to become a VCDX you better start prepping today. It takes a lot of time to produce a proper set of documents and those documents are the key to success. Before you go to the defense make sure you know your design. I know many will think “hey I do know my design”, but go over it with a colleague. Let him question you… You will notice that some decisions were made “just because it is a best practice”, well that is not the right answer I can tell you that. Know why it is a best practice, know why it met you customer’s requirements. Know your design inside out!

 

If you could do the whole VCDX journey again what would you do differently?

Not much to be honest. I used two existing designs and merged these. I made sure I had constraints, assumptions, risks etc. There were politics involved in those projects and I made sure I exactly knew what drove some of the crazy design decisions in there.

Life after the VCDX?  How did your company respond?  Was it worth it

When I took my defense we were at an “off-site” in San Francisco. The people who passed that week were all pulled up on stage during an “award dinner”. I can tell you that I felt really honoured receiving my VCDX plaque from the VP of Technical Service back then, Enis Konuk. Besides that, how cool is it to be up on stage with people like Mostafa Khalil, Kamau Wanguhu and John Arrasjid.
