Juxtaposition Time! Join us at London VMUG to talk AWS! – January 19th 2017

Don’t panic, you’re not imagining things! You did indeed read that title right! If everything goes to plan, Chris Porter and I will be taking the January 2017 London VMUG to a whole new place, with a session on AWS!

Yes, that’s an AWS session at a VMUG! 😮

Why?

For those people who have been living in a bunker on the isle of Arran for the past few years, AWS has been taking the IT industry by storm. So much so, at VMworld 2016, VMware announced their new product “VMware Cloud on AWS“!

Whatever the reasons that VMware have decided to do this (and I’m not going to go into my opinions of that right now), it leaves VMware admins in a position where even if they aren’t already doing some AWS today, the likelihood of them doing so in the near future has just jumped by an order of magnitude!

Meanwhile in a parallel universe...

Meanwhile in a parallel universe…

What’s the session about then?

The session is planned to be a quick intro on the key features of AWS, some tips on how to learn more and get certified, as well as some of Chris and my experiences of working with and designing for AWS (which is rather different to doing things in VMware, for sure!).

Hopefully it should be a pretty interesting session, especially if you haven’t had much exposure to AWS yet!

What else can you see at the event?

As always, there will be many awesome speakers at the London VMUG event. Ricky El-Quasem is even doing two by himself!

There will also be a load of other sessions, so check out the agenda below:

LonVMUG Jan 2017Wrapping up the event there will also be the eponymous vBeers event at the Old Bank of England (194 Fleet St, London EC4A 2LT), so make sure you hang around after and join us for what is often the best part of the day!

Lastly, thanks very much to the LonVMUG sponsors, Rubrik, iLand and Stormagic, without whom it would not be possible to hold these events!

I’m in! How do I register?

You can register for the event at the London VMUG workspace here:

LonVMUG January 2017 Registration

The location is techUK, 10 St Bride St, London, EC4A, which is pretty easy to get to via your preferred public transport methods, though coming in via Waterloo I generally find the bus to be fastest…

If you do see me on the day (I’m 6’7” so you cant miss me), please do come and say hi! 🙂

Top 10 Tekhead Posts of 2016

I’m pleased to say that I upped my game somewhat over the past year, managing to churn out 62 posts in 2016, more than double the 28 posts I produced in 2015!

There were a few other interesting trends over the previous year. The balance between VMware and other subjects has definitely shifted for me, where for example, I wrote well over a dozen posts on AWS.

I guess this is probably representative of both my recent role change, as well as the shift in my customers from being 90%+ VMware houses, to a broad mix of different cloud platforms, both public (AWS / Azure) and private (VMware / OpenStack).

This trend is only going to accelerate in the future, and I suggest Scott Lowe’s Full Stack Journey podcast would be well worth your time subscribing to for great information on how to avoid being left behind as our industry morphs over the coming years!

It’s worth noting that this trend is also mirrored in the top 5 articles alone, which include popular newer technologies such as Docker and AWS. That said, it’s great to see the Intel NUC Nanolab series is still as popular as ever, and people are obviously still keeping their vSphere skills and certs up to date, based on the VCP delta study guide popularity.

You may also have noticed that I have been a little quieter of late. The main reasons for this have been down to starting my new role earlier this year, studying for exams, plus a number of other projects I’ve been involved in (such as the Open TechCast podcast). Hopefully I can find a little more balance between them all in 2017, though I already have a couple of podcasts, a VMUG presentation, and a possible exam lined up for January so I’m not really helping myself on that front!

  1. My Synology DSM Blue LED issue was actually just a failed drive!
  2. Installing Docker on Ubuntu Quick Fix
  3. NanoLab – Running VMware vSphere on Intel NUC – Part 1

  9. Index of Tekhead.it Blog Posts on Amazon AWS
  10. Quick Fix for “The task was canceled by a user” when deploying OVA in vCenter 6

Something Mike Preston and I discussed on our recent Open TechCast podcast episode, was how it can be a little frustrating as a blogger that often an opinion piece which took ages to write and edit will get a small number of views, whilst a quick tip which took a couple of minutes to jot down, might get thousands or even tens of thousands over time!

Gladly, my top 10 this year includes both types, so my time wasnt completely wasted! 🙂

Anyway thats enough from me for now; all the best for 2017 folks!

AWS Certified Developer Associate (CDA) Exam Study Guide and Materials

Following on from my previous AWS exam experience post for the AWS Certified Developer Associate (CDA) exam from Amazon, the following describes the study materials I used towards the exam.

As a reminder, this is my second AWS exam, having completed the AWS Certified Solution Architect Associate exam earlier this year. As such the materials I used to study towards the AWS Certified Developer Associate exam are more sparse, due to the level of knowledge I already have.

For a really full picture of all of the materials I’ve used over the last 12 months, I highly recommend you check out the Certified Solution Architect Associate exam experience and the Certified Solution Architect Associate study guides, along with a number of tips, tricks and gotchas I have posted over the past few months. I also did a podcast recently with Scott Lowe on the subject of learning AWS. If you are new to AWS, I highly recommend you check it out!

Study Materials

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

  • 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 to review as well as the content areas to study.
    • AWS CDA Exam Blueprint
  • ACloud.Guru AWS Certified Developer Associate training course.
    • As with the CSA course, the quality of the production (especially as Ryan and co are a small startup) is excellent. Remember that as Ryan says, they are focussed on teaching you the knowledge to pass the exam, not teaching you everything in AWS. There is no substitute for labbing and working with AWS day to day to become an expert, but you can certainly pass the exam based on this course! This might then help you get your first AWS job and gain the experience you need to be a real Cloud Guru! 🙂
    • The course has around about 10-12 hours or so of content, but I would say it took me 15-20 hours in total between all of the lab work, coming up with my own scenarios to practice configuring different elements, completing the quizzes, and researching any areas where I got a quiz answer incorrect or wasn’t sure of the reasons for a specific answer. Ryan also speaks quite slowly and very clearly, so I find that watching it at 1.5x speed or above can help get through the videos on the areas you know well already. Remember to slow it back down for new content areas of course!
  • QA Architecting on AWS & Advanced Architecting on AWS compressed training course
    • Myself and a number of colleagues completed both of the 3 day architecting courses (standard and advanced) in a rather intense, but very informative 5 day week! This was an awesome course, and really helped my gain breadth and depth of knowledge, but I would not say it was critical to passing the Developer exam itself.
  • White Papers
  • AWS CSA Official Practice Exam and Sample Exam Questions
    • I would say this is a good indicator of the level of difficulty of the actual exam.
    • Sample AWS CDA Exam
  • FAQs
  • Other Articles and Resources – The AWS documentation site is an absolute goldmine of information, and most of the articles are well written and easy to consume. Significantly more so than some of the best known “kb” and documentation sites in the industry IMHO. The following is a list of some of the articles I dipped in and out of while researching for the exam as well as my AWS Tips and Gotchas blog series:
  • And finally…
    • I say this about every single exam I have ever taken – lab it, lab it lab it! It is a million times easier to answer a question based on something you have actually done yourself! Don’t try to just learn the theory, spend a bit of time doing it in practice and you will reap the benefits in both the exam and real life!pass

AWS Certified Developer Associate (CDA) Exam Experience & Tips

The information bellow covers my experience for the AWS Certified Developer Associate (CDA) exam from Amazon. Following this I will post a list of my study materials, so keep checking back for updates or check out my Index of AWS Posts.

Before you continue reading, I would first just say that this is my second AWS exam, having completed the AWS Certified Solution Architect Associate exam earlier this year. As such the materials I used to study towards the exam are more sparse, due to the level of knowledge I already have.

Certified Developer Associate Exam Experience

My personal experience of the AWS Certified Developer Associate exam was that it was quite a bit easier than the Solution Architect Associate exam. Now, I don’t know whether this is more because I have been doing quite a bit of AWS work, as well as writing about it quite a bit in the months since I passed the CSA, or if this was down to the exam being genuinely easier. Most likely a combination of the two, as many people seem to rate the three exams as Developer, Solutions Architect, then SysOps Associate in increasing difficulty.

Either way the exam itself was actually very reasonable if you have any experience working with AWS. The way that AWS seem to structure their exams, is with some general questions across their portfolio, then specific technologies taking precedence in each. The developer exam was no different; there is definitely a distinct bias towards DynamoDB, S3, SQS and authentication. All the things which AWS Developers are likely to use when building distributed and highly scalable applications of course!

It is worth noting that AWS do not expect you to be a developer to pass the exam. You don’t need to know how to code in any language or similar. It would be useful for you to understand the basic format of JSON, but again this isn’t critical to pass the exam. If you want to work hands on with any of the AWS tooling in real life however, this is pretty critical!

The exam itself is 80 minutes and 55 questions. Again AWS (as is their way) do some odd things like not giving you a passing grade requirement, but it’s generally safe to assume that if you get 70% or more, in the Certified Developer Associate exam then you will pass. The Kryterion exam environment is frankly a little poor / dated, but I already wrote about that in the CSA guide here, so I won’t repeat myself again! Suffice to say, read the other article for a detailed overview.

There’s not a huge amount of advice I can give regarding the exam itself, other than if you are stuck, go with your gut. Believe it or not, the most obvious answer is often the actual answer! Don’t second guess yourself and say “No way it couldn’t be that simple!”.AWS Certified Developer Associate CDA Gut Feeling

Things like the specific API syntax used by AWS is generally quite logical, however there are a few weird things! For example, the read commands GetItem and BatchGetItem match syntax with eachother and are logical, but the write equivalents, PutItem and BatchWriteItem, do not! Knowing these types of little weird things can potentially help you come exam time so make sure you memorise some of the more common API calls.

It is also very worthwhile practicing your DynamoDB maths, as AWS expect you to be able to do this in your head. Memorising and practicing Ryan’s simple method really helped me to get my head around it.

Finally, if there is one thing I recommend you read, it’s the DynamoDB FAQ. This is a goldmine of information that will stand you in good stead for both the exam, and developing solutions on AWS!

Best of luck, and if you found this article useful, please leave a comment below! 🙂
