VCDX #: 243

How did you get into using VMware?

I was voluntold! I learned VMware while serving in the military. My direct supervisor instructed me to upgrade an ESX host; I had no idea what VMware, ESX, or virtualization even was at the time.

What made you decide to do the VCDX?

It seemed like the next logical step. I had achieved multiple VCAPs and VCDX was next. It was more of a self-validation than anything. I also hoped that it would help open up doors in order to take my career to the next level.

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

A little over three years. I attained both VCAP certifications on v5 in 2013. As for actively pursuing VCDX, it took 10 months. I began rewriting my design (had briefly started the previous year) with my VCDX partner in February 2016, submitted in May, unsuccessfully defending in July, resubmitted in August, and succeeded in November.

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

If you are considering pursuing the VCDX, I would recommend doing a self assessment and evaluating your strengths and weaknesses. Work to shore up the weaknesses because as an architect you must be well rounded in many technical areas. Secondly, practice public speaking. Your soft skills matter as much as your technical expertise. And lastly, set realistic goals for yourself and find a study group that will hold you accountable.

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

Generally speaking, I wouldn’t change much. Failing was a huge learning experience and helped me get a clearer understanding of what the panel was looking for. I would spend more time up front doing mocks with more people and working on my presentation earlier.

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

My company was super supportive because I own it! Ha! As for post VCDX life, it has mostly returned to semi-normalness. But, I would say that the process and my preparation have changed my perspective and how I approach the design process. I’d say it was worth it for the personal growth and the people you meet along the journey.

VCAP6-DCV Design Objective 1.1 on the #vBrownbag

Last night I decided an hour before the planned time for the first vBrownbag VCAP6-DCV Design Objectives series to pull together a presentation and take on the objective. Jason Grierson had partly put his hand up for the objective but was unable to complete his before last night but agreed to join me on the broadcast and it worked out a life saver.Unfortunately due to some very poor hotel Wi-Fi I had some issues getting my presentation to show on the broadcast and so Jason stepped in to go over the parts he had done for the objective and did an unbelievable job and then I presented mine afterwards so we managed to have two VCDX’s covering the one objective so hopefully it brings extra value. My presentation from the broadcast is below

The recording of the session is also below

VCAP6-CMA Design achievement unlocked

yeahbuddy

This morning on my second attempt I passed the VCAP6-CMA Design exam. For those that aren’t sure what the exam is it is the VMware Certified Advance Professional –Cloud Management & Automation Design exam. The exam is a 3 hour exam where you have to answer 23 questions consisting of a variable number of drag and drop as well as Visio style question all around vRA 6.2 design.

I’m not going to break any NDA’s around the exam so please don’t ask. What I will do however is list here what resources I found helped me the best to pass the exam this time around and will add these resources if they are not there already to my VCAP6-CMA Design study resources page and also give advice keeping to the NDA that I feel would have possibly helped me pass the first time.

  • The VMware Cloud Automation: Design and Deploy Fast Track course is really great and certainly fills in any gaps in your knowledge that you might have. I was fortunate to be able to do it due to having access from my work white labelled as VMware PSO. The course is good but if you have been doing enterprise level vRA designs for a number of years like I have it can be very slow at points!!
  • The the vRealize Automation Reference Architecture from VMware was brilliant when i started learning vRA and it is still true. One word of advice is to not only spend time learning vRA components which are obviously important but also what supporting technologies are required for certain functions and capabilities to be possible (NSX, vRB, Endpoints, vSphere etc etc) .
  • Remember the exam is currently based on vRA 6.2 so all those fancy features you get in vRA 7.x aren’t possible during the exam so you need to know how it was done previous to those features if possible at all. A great resource I used to remind myself how it was done in vRA 6.2 was to  read the reference architecture i listed above.
  • This ones a biggie and i used two different resources for it, it is the various roles in vRA and what permissions each gives you. Sam McGeown’s mindmaps were the first I used as well as Grant Orchards mindmaps. Knowing what each role does and what permissions it gives is extremely important and maps directly to VCAP6-CMA objective 4.2. Remember a good design is all about giving the least privileges possible.
  • This one I didn’t expect to have to learn as much about and ties into point number two, I read the NSX Design Guide as design objective 3.5 mentions NSX but the amount of NSX knowledge needed for the exam was certainly much more than I expected so for my second attempt i made sure I was prepared.
  • This is part of the study resources for the exam but the amount of application services weightage amazed me so make sure you have read and fully understand all the capabilities and requirements of vRealize Application Services.
  • Last one that is weighted more than I expected is machine extensibility which ties in objective 8.2.

The exam is certainly worded strangely and one bit of advice that i stumbled across during my second exam is that if the text in the question seems to be a repeat of an earlier one and the options to build it don’t match then try click the wide option for the question text and it might bring up the correct text for the question. Good luck if you are planning to take the exam and for me it’s now onto prep for my VCDX6-CMA defence in just over a week.

VCDX #: 231

How did you get into using VMware?

I started with VMware Workstation in 2000 when I was writing code for a living. I started working with ESX in 2005 with version 2.5.1. VMware products became my main focus with the release of VI3.

What made you decide to do the VCDX?

This is complicated. Mostly the challenge and to prove I could. In seeking validation, I ended up gaining far more. I’m easily twice the architect now compared to when I started.

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

I completed my VCAP-DCD in February 2014. I guess I was passively preparing from that point until I began in earnest writing my design in May of this year (2016). I submitted in July and worked on my deck from the day I submitted until 2 days before I defended in September. In all I probably spent 200 hours this summer between writing, revising, and raw study.

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

Three points:

1. Get a mentor.

2. Get a study group of people you respect and trust. Mine was fantastic and I’m sure we will be friends post VCDX for a long, long time.

3. Understand your use case. What the workloads you are running on your clusters actually do for the business matters. Understanding the business impact of the applications leads to justifying design decisions. If you design an infrastructure for it’s own sake without taking this into account, I’m almost sure you will fail the defence.

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

I would have used a real use customer design. Mine was entirely fictional. The upside is I’m pretty sure I’m one of the only folks to pass on the first attempt with an entirely fictional design and without working with a partner(s).

The downside is that it made the process significantly harder. I had to make up all my performance and sizing data and make it feel real. That was very hard, and I still think I could have done a better job of it. If I had those numbers collected, because they were real, it would have saved me significant time.

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

My goals around learning include knocking out all 5 AWS certs by the end of the year and then starting on my VCDX-NV.

My company has been pretty great about everything, however with Rene (VCDX #133) as my boss I would expect no less.

In the end was it worth it? Yes. Would I do it again? Yes.

The friends I gained and the skills I cultivated were well worth the effort. Without a doubt the VCDX journey changes you in ways few things can.
