With this ping pong of questions and answers, we continue with a new sort of subject on the blog: the interviews. There are 10 questions that will leave us valuable information such as who is the interviewee, his experiences and his point of view about the present, past and future of technology.
Interviewees are mainly writers, bloggers and people related to the technologies discussed in this Blog.
Today, we have the pleasure to know more about John Arrasjid. John is principal architect at VMware, VCDX-001 (awesome!), principal author of VMware VCDX Boot Camp book and he work in VMware education division.
1- Who are you? What do you do?
My name is John Arrasjid, a Principal Architect at VMware and VCDX-001. I have been with VMware for almost 11 years and have worked in professional services (consulting), the Cloud Services team (developing cloud reference architectures), and currently in education. I have released 5 books through the USENIX Association Short Topics in System Administration series and VMware Press. I am also the Vice President of the USENIX Association Board of Directors. My primary focus today is on advancing the number of architects in the industry focused on virtualization and cloud. My new role in education is to develop the architecture track to accelerate candidates achieving VCAP and VCDX level certifications and ensure success in the field with solution architecture.
2-When did you see your first Virtual Machine?
The first Virtual Machine I worked with was on an Amdahl mainframe (IBM compatible mainframe) in 1988. I started working with VMware virtual machines in 1999 with the first beta release of VMware Workstation when a friend and I ran a startup called WebNexus Communications. A lot has changed since those two dates.
3-Can you tell to us the virtualization technology you found most amazing?
I think virtualization in general has been amazing but it has been around for a long time. In my work at VMware one of the most amazing technology breakthroughs would likely be VMotion. The reason is that so many other technologies have leveraged this and it was also the first time I watched live migrations between systems of fully loaded production workloads without issues. Having done IT for years prior to VMware, this technology addressed the problems faced regularly by IT professionals for maintenance, changing workloads, upgrades, and other areas related to infrastructure upgrades.
4-If you had to recommend study a specific virtualization subject, what would be?
I would recommend studying the concepts around 'software defined data center'. This includes server virtualization but also networking and storage virtualization. This is a big area but is something that continues to grow and change the way we do things every day. If I were to pick a subset I would recommend studying the areas that are closely related to your role and your needs.
The two areas that continue to drive change are Software Defined Networking and Software Defined Storage. They continue to evolve to meet cloud and data center needs. If you have specific roles that you have, then I would make additional recommendations focused on those roles.
6-What is your point of view about virtualization technologies for the next three years?
We will see further virtualization growth in areas outside of computing. Networking and Storage virtualization are here already. Support for accessibility, reliability, scalability, and performance will continue to be areas that VMware and other vendors can provide value to IT organizations and the businesses they support.
7-What new company got your attention in the last two years?
Nicira was a pleasant surprise as the acquisition by VMware captured the industry's attention and the technology drives software defined networking as a key to both virtualization and cloud. They also caught my attention with 4 VCDX on staff and plans to grown that even more.
Another company is Nutanix that has 4 VCDX on staff and plan to add more. I think that if we had a concept of a VMware Certified Design Partner, they would be one of them. The concept means that a company ensures their top performers are validated by vendors and the industry in their competency areas. VCDX Methodology drives success and other companies, like AHEAD and DELL, join Nutanix and several others in having 2 or more VCDX on staff.
8-Could you recommend three Blogs you usually read?
There are quite a few but I’ve found that some of the Blogs that consolidate other blog postings provide me with a quick way to stay abreast of what is going on and peoples thoughts on technology and operations.
I would say the vBrownbag sessions, The Virtualization Practice Newsletter (Bernd Harzog), and The VMTN Blog (John Troyer) are ones I follow regularly. I also tend to peruse the Community Forums and subscribe to several groups tied to architecture and certification.
I’d like to list a top 3 for my blog favorites but I have more than 3. Here is a sampling of those that blog and tweet that I view frequently. I will list names here: Steve Kaplan (@roidude), Michael Webster (@vcdxnz01), Cormac Hogan (@VMwareStorage), and Duncan Epping (@YellowBricks).
9-If you didn´t work in IT today, what do you think you would work in?
That is a good question as I’ve touched a lot of things over the years. I think it would likely be in teaching as it has huge overlap with what I love to do. Fortunately my current role now gives me this opportunity.
10-What can you tell us about your next book?
I’m currently working on two books but can’t yet reveal the details. That will be made public sometime in Q1 2014.
I can cover some of the current activities with the boot camp series. As many know I’ve been developing and running VCDX boot camps since about 2008/2009. I have recently completed the VCAP Design boot camp and am currently working to finish the VCAP Administration boot camp. These new ones provide guidance on the type of scenarios and labs included and strategies for both studying and taking the exam.
Thank You Jhon!!!!
