I have watched numerous videos and seen quite a few slide decks which cover tools such as Puppet, Chef & Ansible. I have witnessed an entire rack of servers PXE boot, installing their base operating systems, configuring their services and then finally checking out a copy of a production ready codebase. Even after seeing this several times the old school sysadmin in me still thinks this is witchcraft. In the world of dedicated servers or virtual machines this is great, however when it comes launching an auto-scaling instance in a service such as Amazon Web Services using orchestration tools in real-time could be the difference in your application staying online or failing....

As someone who deals with the word “Cloud” as part of their day job it can get very confusing. When a client or colleague says “I want cloud” or “what about hosting it in the cloud” what does it mean? Well, in my line of work it could mean any of the following …. Virtual Machines hosted on a highly available hardware platform Instances hosted in a an auto-scaling available configuration Using Content Delivery Networks (CDN) for content Uploading static content Distributed Object Storage Software as a Service (SaaS) Platform as a Service (PaaS) Thats only a small list of what services which the word “Cloud” is used for....

All of the posts on orchestration on here have been about Puppet on CentOS however last week I had need to script an AWS architecture and then launch instances built with Packer↗ into it. After much swearing I managed to hack together a python script which used Boto↗ to create a launch configuration and register it with an auto-scaling group, I then used a second script which re-cycled instances behind the Elastic Load Balancer which were launched with the previous launch configuration....

At the end of my last post about Grunt I mentioned that I will be adding code to concatenate the javascript, compress the images and also tidy the code up abit. I have now done this …. Javascript I moved all of the javascript to a folder called _js and then set up the following …. More Grunt & Jekyll 1/7 js: { src: [ ‘_js/jquery.min.js’, ‘_js/jquery.plugin.min.js’, ‘js/bootstrap.min.js’, ‘_js/jquery.flexslider-min.js’, ‘_js/smooth-scroll.min.js’,’ _js/skrollr....

As you may have noticed, the website looks different to how it was previously. I decided it was time for a refresh and I wanted to make the design a little more interesting. While Jekyll↗ & Github↗ pages use SASS↗ the Bootstrap theme I settled for uses LESS↗ . This meant that I needed to compile all of my CSS outside of Jekyll. Most of the articles I found say use either Gulp↗ or Grunt↗ , looking at the syntax of the two I preferred Grunt as it didn’t look like code....

Yesterday, I had day out of the office with Danny↗ at the 2014 London PuppetCamp↗ . It was the first time I had attended a PuppetLabs event, though I have streamed plenty of video from past camps and conferences. It was interesting to see how best practices had moved on (answer, lots) since I first had my Puppet epiphany over a year ago. For me, and in no order, the most interesting talks were …....

As mentioned in a previous post I tend to send most articles I am interested in reading to Pocket↗ so I can read them when I have time.
