  • How to become an AWS Certified Developer

    This year I (Rory Schellekens) achieved the AWS Certified Developer – Associate Level certificate. AWS Certifications are popular at the moment, especially the solutions architect certification. I chose the AWS Developer as a start, but the most popular to start is the Solution Architect. I chose the developer because I want to go for DevOps Engineer – Professional Level. Still considering if I should go for the DevOps Engineer certificate or first build up knowledge about Microsoft Azure.

    Anyway here is how I achieved the AWS Certified Developer – Associate Level: First thing is to get an AWS account; the first year you will have a so called free tier where you can make use of services for a specific time for free.

    Anyway here is how I achieved the AWS Certified Developer – Associate Level:

    Read the pages about the certification itself, it has important information:


    Practice the exam questions which Amazon Web Services shares:


    Follow the A Cloud Guru training on Udemy, these trainings are giving by Ryan Kroonenburg, see his page on Udemy.

    I bought the following courses from A Cloud Guru on Udemy:

    • AWS Certified Developer - Associate 2017
    • AWS Certified Solutions Architect
    • AWS Certified SysOps Administrator


    For the AWS developer I watch two times the Developer course and one time the Solutions Architect.

    Recommendations for buying the A Cloud Guru courses on Udemy:

    • Be careful not to buy the exam questions instead of the course.
    • Wait till they have discount on Udemy, the course price can drop to even 10 euro per course.


    I also watched some videos from vBrownbag. They have two series about AWS:


    After following the course and watching the videos of vBrownbag I would recommend to study the FAQs and white papers and understand the questions of the exam samples of the AWS Developer Certification. The most important FAQs and white papers are mentioned on the Prepare for certification page.

    Still this is not enough, I found a topic on A Cloud Guru which points to different videos and documentation of AWS, which found helpful for the exam. After watching these videos and read most of the articlesi, you should be ready to get the certification without a problem.

    Oh yeah, here is a link to the topic

    If you are new to Cloud Computing have a look at on of my first blog post called A Career in cloud computing, where to start

  • Cookie Monster

    Few weeks ago I removed my S3 Lambda integration to Keen IO, because most of the hits were from Robots. Today I decided to put back Cookie Monster also known as Google Analytics. Only this Cookie Monster does not eat cookies but give them away. So please let your browser eat them, so I can find out if you like this website (by visiting multiple pages) and where you from.

    I also add one Microsoft Certificate, I hope to add and update some certificates the coming weeks.

  • Small Update

    Today I did some small updates on the website and update some old posts and changed our motto.

    Sadly I have to say I will not write Part 2 and Part 3 of AWS S3 Statistics to Keen IO with Lambda. For Part 2 see https://aws.amazon.com/documentation/lambda/ and for Keen IO Dashboard see http://keen.github.io/dashboards/.

  • AWS S3 Statistics to Keen IO with Lambda (Part 1)

    For CloudYourSky.com I wanted to have visitor statistics without cookie tracking. After some searching I discovered Keen IO . Keen IO is an event tracking tool with powerful analytic capabilities. Except that Keen IO is a great product, Keen IO has also a great community, see Keen IO Community.

    Originally I wanted to use the Keen IO Javascript client, who sends the events of my website to Keen IO. Only some ad blockers block Keen IO for such activity. That is way I decided to move from Github Pages to Amazon Web Services (AWS) Simple Storage Service (S3) . AWS S3 can serve static HTML websites and has the possibility to generate logs. These logs can be downloaded and then sent each log entry as an event to Keen IO. Only problem is that I need a server to automate this procedure. Do I really need a server? No!

    Amazon Web Services has a service called Lambda, AWS Lambda is a compute service that runs your code in response to events and automatically manages the underlying compute resources for you. Thanks to Lambda there is no need for a server which runs 24/7. Plus the log entries are sent to Keen IO just after the log file is created, this is much faster then downloading the log entries every hour. Another plus is that the first 1 million request are for free, see Lambda Pricing.

    How does it work: AWS Lambda receives S3 “Object Created” events every time a log file is created. When Lambda is triggered by an event a piece of Javascript code is executed which reads the S3 log file and converts each log entry to a JSON object. The JSON objects are then sent with a HTTPS request to the Keen IO api. Keen IO stores the events and sent a response back with success true for each event.

    To avoid making this article too long I split this article in 3 parts. This was part 1 and soon part 2 and part 3 will follow:

    • Part 2 will provide instructions how to configure Amazon Web Services and Keen IO to sent events to Keen IO
    • Part 3 will provide instructions how to setup a Keen IO Dashboard.


    For people who can not wait on Part 2, the Javascript code is already available on Github: lambda-s3logs-2-keenio.js.

  • Back from Break

    As you noticed there were no updates the last couple of weeks. There is a very good explanation for that! I became a father of a beautiful girl!!!

    I am planning to work on the site again. Mainly adding new certificates and Courses.

  • OpenStack Certifications

    OpenStack is an open-source cloud computing software platform and currently the most populair one. OpenStack is founded by Rackspace and NASA and currently has a lot of supporting companies like AT&T, Ubuntu, HP and IBM.

    OpenStack is used by many companies to set-up their private cloud infrastructure. When you are interested in installing, configuring and maintaining a private cloud have a look at the following OpenStack Certifications:

  • A Career in cloud computing, where to start

    You don’t need to know the basic concepts of Cloud to get a job in cloud computing or be good at your job in the area of cloud computing, but it makes you much more professional when you need to explain cloud computing to a customer.

    That’s why I suggest you to start with a basic course, my favorite course of the moment is Cloud Models, Architecture and Risk Management of Charles Sturt University. The course is given by Peter White and is explaining the basic concepts of Cloud according to the NIST definition. NIST is the National Institute of Standards and Technology (US).

    After following the Cloud Models, Architecture and Risk Management course, I would recommend to get a basic cloud certification. Since you already followed a course, you can go for the CompTIA Cloud Essentials or EXIN Cloud Computing Foundation. These certifications don’t require you to follow a course as requirement to do the exam. I also recommend to buy the book Cloud Essentials by Kirk Hausman, Susan L. Cook and Telmo Sampaio, which is a CompTIA Authorized Courseware for CompTIA Cloud Essentials. The good thing of this book is that it also discusses the EXIN Cloud Computing Foundation certification. This book discusses the subjects which are not handled in the Cloud Models, Architecture and Risk Management course.

    After passing for one of these certifications, you will full understand the basic concepts of cloud computing.

    Good luck with getting one of the these certifications!

  • Time to go public!

    Ok, ok, I did not check the spelling and grammatic yet, but the vendor-neutral certifications of the vendors we selected are published. Check the vendors, or check our certifications page for a direct overview of the certifications.

  • Added First Certificate!

    CloudYourSky.com has added the first certificate, the popular CompTIA Cloud Essentials of CompTIA. The CompTIA Cloud Essentials is mentioned in most of top 5 or top 10’s of Cloud certifications, like:

    The CompTIA Cloud Essentials is a good starting point, when beginning a career in cloud computing.
