Open TechCast – The One with Pat Gelsinger

The title does kind of give it away, but the co-hosts of our humble little community podcast were fortunate to spend 40 minutes or so this week with VMware’s CEO, Pat Gelsinger.

We discussed Pat’s journey into to VMware, the difficulties of maintaining a healthy work/life balance, gender equality in the workplace, the transition from traditional licensing models, the future of SDDC and much, much more!

Needless to say, it’s been pretty difficult keeping this one under wraps, especially as we didn’t want to jinx it!

The Interview

Kev, Ather, Amit and myself were able to be there in person, but we also managed to dial in Gareth remotely from the UK via Zoom, for a full complement of co-hosts! At one point in the show we happened to be discussing Moore’s law, when Moore’s cousin Murphy decided to jump in unannounced!. Despite putting fresh new batteries into the recorder shortly before the interview, they gave up the ghost, mid-session!

Fortunately, our keen eyed co-host and sound man, Kev, spotted the issue and was able to avoid disaster! There were a nervous few minutes after the session when we were testing the recording for corruption, I can tell you! It just goes to show that no matter how much planning you do, unexpected events can still crop up!…

Anyway, massive thanks again to Pat for taking the time to hang out with us, and we very much look forward to a re-run next year if the opportunity arises! 🙂

How can I listen?!

Docker – State of the Nation (aka Observations of a Brit)

Docker Logo

It may surprise you to learn that Docker is actually quite old now (at least in Startup terms!), having released the first version of their very cool software in March 2013!

Throughout that time, Docker (the company) have moved at a fairly rapid pace in terms of feature and etween

ug releases, with an average of a point release about every quarter and minor releases every month (or more)!

Whilst sitting here awaiting my flight to VMworld Europe 2017, where there are MANY MANY MANY (MANY!) sessions on Docker, Photon, Kubernetes, etc on the session schedule, I am prompted to consider Docker’s rise to popularity, and finish off a post I begun a few months back after Tech Field Day 12!

Well come on Galbraith… get on with it then!

My experience in UK IT industry over the last (nearly) 15 years has taught me a few things, one of which is that whenever new technologies begin serious adoption in the US, it usually becomes popular in the UK within 2-3 years. That said, this number has been squeezed down a little in the past few years as companies move towards more agile development and deployment methods. Fail fast is becoming the mantra of many more organisations, though some people I speak to still wake up with night sweats at even the thought!

The first time a customer asked me about Docker in the UK was over 3 years ago, yet in all that time, people I talk to outside of the social media bubble many of us live in have been virtually silent about it; that is until now. Docker is becoming a weekly conversation topic now with a lot of organisations I talk to, with a many people wanting to jump on board the band wagon. The switch from an operating system-centric view of the world, to a more application and service-oriented (or should that be microservice-oriented) view of the world is becoming far more prevalent in my experience.Docker Swarm

Drivers to Docker Adoption

So what is it about this Docker stuff which seems to be catching the attention of people I talk to? A few common themes I hear are:

Automation of code deployment pipelines (CI/CD) to increase business agility
I think this is probably the number one driver to Docker adoption for people I talk to. Automation of CI/CD pipelines has become so common now, it is almost becoming the norm. Yes, it is tricky to do this with more traditional applications, but it certainly isn’t impossible. Using containers as the delivery mechanism for your application provides very consistent and repeatable outcomes. I mean, you can even get Oracle DB in a container now?!?!

That said, once you dockerise your applications there are many further challenges you will run into, including something as simple as how to apply your current security tooling, policies and proceedures to these new environments.

Maturity of the platform
The Docker code base and third party ecosystem has finally reached a point of maturity where many of the networking and storage issues of the past are beginning to reduce to within acceptable risk boundaries.

Improved cross-industry support
Following this maturity model, a swathe of vendors have put their names behind the Docker ecosystem; from VMware to Openstack, AWS to Azure, Google to Cloud Foundary, everyone is getting on board! You no longer have to buy support direct from Docker (the company), but can instead get it from your cloud vendor, along with a managed orchestration tier too, such as Docker Swarm, Kubernetes or Mesos!

Because Cloud
Yes, you can Dockers your existing applications for use on premises, but many organisations I speak to are using Docker as a method to allow their developers to write code on premises, test in their dev environments on prom or in the cloud, then deploy in a consistent fashion to their brand spanking new Production cloud platforms. PaaS solutions such as Azure WebApps and AWS Elastic Beanstalk are becoming a good option for customers who just want to write code, but for those who want that little bit more control, Docker gives them flexibility and consistency.to the cloud

CIO/CTO CV Padding
I hate to play the cynic, but I think there is definitely a significant percentage of CIOs/CTOs who are doing “digital transformations through containerisation and cloud” specifically to pad out their CVs and help them get a better gig.

This is otherwise known as a “Resume-driven IT Strategy”!

I am aware of one CIO who deliberately went to a cloud platform, even though it was significantly more expensive than a traditional managed hosting solution of a similar spec, when their business case and steady workload drew few, if any discernible benefits from the use of cloud.
CIO CV Padding When I hear people refer to technologies such as VMware vSphere as “Legacy” it really drives home to me the shift we are all going through, yet again, in the industry. This is another reason though which CIOs/CTOs/Heads of IT tell me they want cloud and containers. That said, I still struggle to find a single person who doesn’t have at least one physical server in their infrastructure, so just like the mainframe before it, I don’t think the hypervisor is going away any time yet!

The Tekhead Take

As expected the lag of a couple of years from the US to the UK in adoption of containers was apparent, but now is most definitely the time! Despite both positive and negative reasons for integrating it, Docker has become the part of the information technology zeitgeist in the UK…

I was fortunate enough to meet with the product team from Docker at Tech Field Day 12 towards the end of last year. It was a really interesting session which covered many of the enterprise networking and security features recently introduced to the platform, along with Docker’s new support offerings. I highly recommend checking it out!

Some of the other TFD12 delegates had their own thoughts on the session and Docker as a whole. You can find them here:

Disclaimer/Disclosure: My flights, accommodation, meals, etc, at Tech Field Day 12 were provided by Tech Field Day / Gestalt IT, but there was no expectation or request for me to write about any of the vendors products or services and I was not compensated in any way for my time at the event.

Microsoft Azure Architect 70-534 Exam Study Guide & Resources

Azure Architect 70-534

Following on from my previous Microsoft Azure Architect 70-534 exam experience and tips post, the following article describes the study materials I used towards the exam.

Having been warned that the exam was a bit tricky, I made sure to do more studying for this than most exams, probably spending fast approaching 100 hours to prepare. Based on my actual experience I believe I could have reduced this a bit, for example by dropping the Pluralsight course altogether (even though I really like them, it is too out of date to be useful, other than for historical knowledge).

Microsoft Azure 70-534 Study Materials

Whilst studying for the exam, I used the following study materials:

Training Courses

  • Pluralsight – 70-534 by Orin Thomas
    • Pretty out of date now, but an ok intro if you have a bit of extra time to really reinforce things. I love Pluralsight, but this course was just too far out of date to be really useful.
  • Linux Academy – 70-534 Prep Course
    • Excellent course, and pretty well presented by Doug Vanderweide. This does cover most of the topics at a broad level, with some deep dives. It is not enough to pass the exam on its own, however.
    • The BEST thing about this system (IMHO) is the Flash Cards. I did all of the decks provided by Linux Academy, and some bits of the other ones.
    • Doug, and the “Architecting Microsoft Azure Solutions Exam 70-534 Prep” deck from “Dominic”. The great thing with these is that you can just pick them up and do them for 5-10 minutes when you have some spare. They are also really good for helping you remember the ridiculous and pointless minutia which you need to know (such as the precise specs of individual names instances, e.g. A8 vs A10).
    • The quiz at the end of each section was also pretty useful.
    • I believe they have also just introduced some hands on labs, which will also help to solidify things, as well as help you remember the specific order in which certain implementation steps need to occur.
  • Udemy 70-534 prep course from Scott Duffy
    • I only found this one with a couple of weeks to go until my exam, so only had time to watch the videos described as updated in 2016/2017. This was useful however as it covered several areas not included in the Pluralsight / Linux Academy courses.
    • The best thing about Scott’s course (which was glaringly missing from Linux Academy and Pluralsight) was that it asked you to do labs with your Azure test account, then showed you how to do them afterward.
    • Scott has also released some practice tests, which I bought (on offer for £10) but then didn’t have time to go through!

Fry shut up and take my money

Preparation

  • 70-534 Exam Blueprint
    • This is always the go-to document for almost any current industry certification, and should be used as your primary guide for resources and areas to study. In the case of the AWS Exam Blueprint, they actually direct you to specific white papers, docs or FAQs to review as well as the content areas to study.
  • Labs
    • Normally I would lab like crazy to learn a new technology, as I genuinely believe you learn something best when you get your hands on it. I only managed to get a few labs done in Azure, purely down to lack of time. To be honest I really felt it when it came to exam time, and there were a couple of questions where I really wished I had created at least one or two ARM templates and configured a few bits via PowerShell, just to help memorise syntax.
    • You can get a free $25 of credit per month by signing up for the Microsoft Cloud Essentials scheme (https://www.microsoft.com/cloudessentials), which is more than enough to spin up a few services.
    • Concentrate on learning the ORDER in which you do things, as this is a learning outcome for MS.
    • Reading other people’s exam tips (just google it!)
  • Practice Exams
    • I had purchased an exam voucher which gave me the exam, a free retake and a free MeasureUp practice test, for less than the full price of the normal exam!
      The MeasureUp practice test was very good prep as it had LOADs of questions (179 IIRC), and covered a broadly similar set of topics. There were one or two questions in there which seemed to be out of date, but when I got to my actual exam, I had a couple of legacy questions, so this made sense to me after the fact! What I did was do an untimed exam with the setting that tells you the answer after you hit next every time. That way as soon as I got a question wrong, I then went and read up more on the specific topic.
      This was absolutely invaluable in my prep as I think I got just under 70% in the MeasureUp, but passed comfortably in the actual exam (largely due to MeasureUp prompting me to “fill in the blanks” to my knowledge). This is an excellent resource, and highly recommended!

practice

  • Exam Voucher
  • FAQs and Docs (over 75 articles – see below)
    • I skim read these looking for key points. I copied these into a giant OneNote file for future reference and rationalisation!
    • If you want to be sure to absolutely nail the exam, read the FAQs. If the exam has indeed changed and become slightly easier (as I suspect it may have), then you may be able to get away without this.
    • The extremely long list below is what I read to augment my own knowledge; do not feel you have to read any or all of them, this is entirely at your own discretion!

The following is a mahoosive list of all the FAQs I read, as per the above:

Azure Architect 70-534

The information below covers my Microsoft Azure Architect 70-534 Exam experience. Following this I will post a list of my study materials, so keep checking back for updates!

One real positive for me when taking this exam was that I realised if you have an MCSA 2012, you do not need to take another Azure exam to achieve the MCSE title. Handy, especially as I have been pretty vocal about my thoughts on re-certification for versioned exams!

Microsoft Azure Architect 70-534 Exam Experience

Almost everything I read in the run up to taking the Azure Architect 70-534 exam, suggested that it was going to be pretty tricky. Many people suggested to me it was harder than typical MS exams. For those of us who are already a bit cloudy, harder than the AWS SA Associate exam but easier than the SA Pro.

My personal experience (having done both) was that it was a little harder than the AWS SA Pro exam, mainly in prep time and breadth of information, but and the reputation was perhaps a wee bit overblown. Don’t get me wrong, it was definitely tricky, but I have a sneaking suspicion that they may have dumbed it down a little in the past few months, as my experience did not quite match that of those who came before me!

tricksy Azure 70-534

The scoring methodology was WAY better than many other exams I have taken in the past (including from Microsoft). When you have a multi-part answer (e.g. choose 3 of 5, etc), then for each correct PART you get a point. In other exams, one wrong selection means “nil points”! In the 70-534 exam, I could have got one wrong selection in every multi-part answer, and still walked away with half or more of the points, which is AWESOME! This really took the pressure off!

The exam is very similarly formatted to most other MS exams, with a couple of notable exceptions. There is a section with standard multi-part, ordering, drag/drop, multi-choice as you would expect. Once this is completed (or perhaps before?), then you do a number of case studies. Note: Once you complete each case study, you cannot go back to it, however, the timing for the case studies was cumulative, so you don’t have to worry if one takes you a bit longer than another.

The number of questions I had in my exam left me with plenty of time, vs some of my colleagues who have done it in the past as well as since, who had 50% or more questions and case studies than me (I had 39 questions spread across all sections of the exam). I can only suggest that perhaps there have been some changes of late which mean you may or may not end up with more time per question.

It’s also worth noting that one or two of the questions I received were based on ASM (i.e. classic) instead of ARM! Not enough that it would be worth learning ASM, but don’t be surprised if something does come up.

Exam Tips and Advice

Here are a few tried and tested tips for most exams as well as specific to the 70-534 exam (based on my experience):

  • Flip through the case study questions as you get to each one to get an idea of the kinds of questions being asked (e.g. security, authentication, networking, etc) so that you can bear these in mind as you read the case study.
  • Don’t worry too much about the clock, they give you plenty of time, especially as there is no specific time limit on the individual case studies (I think there may have been in the past?). For around the number of questions you are likely to get, this is loads of time.
  • Personal opinion: Old questions are dead to me! What I mean by that is that I don’t mark questions for review and once I click Next I never, ever, ever, ever, [ever!] go back. Chances are if I wasn’t sure about an answer and I go with my gut, it’s more likely to be right. If I sit there paralysed with indecision, I just waste time (or worse, potentially change a correct answer to an incorrect one!). By the time I hit the end of an exam I generally have a feeling whether I have passed or not, so going back to get a couple of extra points is a waste of time and I am just desperate to see the result! 🙂
    The one and only contradiction to this rule is if I come across a later question which immediately triggers me remembering something, or even blatantly answers a previous question by asking another. These are as rare as hen’s teeth though!
  • Finally, this may sound a bit cryptic, but I can’t go into any detail obviously due to NDA. All I can say is don’t get weirded out by what seems like an odd handful of questions at the start of the 70-534 exam. I got some which didn’t make sense to me at all until the end of the series (which doesn’t allow you to go back). I can’t go into more detail than that, but hopefully this preps you more than me, so you are not as surprised!
Architect Grumpiness

I do have one complaint about this exam which I will therapeutically air publicly now; why on earth as an “Architect” exam should anyone have to memorise the thousands of possible combinations of PowerShell commands, or indeed any commands whatsoever?! Fortunately, the percentage of the exam weighted towards this is small, but it is ridiculous IMO. 532/533, yes! 534? Stupid!

There also seems to be a key focus on understanding the exact specs of exact machine types. IMO this is also dumb as with any cloud platform you simply pull up your machine list and match the right machine at the time. Wasting time memorising the spec of every A-series, D-Series, etc machine is completely pointless, but is unfortunately required reading (at least as a minimum to remember the key “odd” ones, such as which provide RDMA).
