Implementing Cron Jobs with Elastic Beanstalk
If you have worked with cron jobs with Elastic Beanstalk then you know they can be confusing starting out. Here is a simple solution that I use. It prevents duplicate cron tasks, and makes adding new cron jobs really easy! 1. In your .ebextensions/project.config, add a container command (it is listed first in my application): … Continue reading

I wrote a short post earlier in the week titled Eucalyptus Cloud on Ubuntu 13.04 SE. This is the promised follow-up to that post and has since been revised which I will explain below. I often use Ubuntu in development environments due to the community support and large availability of libraries and third-party repositories. Over the … Continue reading
Preface I originally wrote this comparative analysis a couple of years ago but being in the Media industry the question comes up a lot regarding what is the right CMS platform to use. In this particular case I was evaluating Drupal versus Django as a replacement for a third proprietary system. Before rejecting that comparison … Continue reading
I came across an excellent, practical, and easy-to-implement project this week that utilizes the Raspberry Pi and Geckoboard in order to power a company dashboard. As a result I went on to implement my own version with a few minor additions and customization so I made notes to share. I had a 42″ plasma … Continue reading
There are as many backup solutions on Amazon as there are applications. I have launched many EC2 instances in AWS and, while the storage configurations vary for each instance – instance-store, single EBS volumes with an ext3 filesystem, multiple EBS volumes with an xfs filesystem with a virtual group and logical volume, etc. I needed … Continue reading

- I will write a new post soon (when I can catch up on some much needed sleep) regarding how to create your first EBS image. It is certainly a challenge and every resource that I have found so far has an issue: not enough detail, skipping parts, inaccurate commands due to version incompatibilities, etc. But, my greatest challenge was actually the grub boot loader configuration. I will expand on that as well but until then this is a great overview for configuring grub (although it does not cover the installation itself which is equally critical), and in particular - setting the root volume label, which I did not read in any related tutorials: Eucalyptus | Create an EBS image from existing image.
- As you grow your infrastructure on Amazon Cloud additional monitoring is imperative. Here is an excellent "how to" for recording memory utilization as a custom metric: https://forums.aws.amazon.com/message.jspa?messageID=266893 Related articles New Amazon CloudWatch Monitoring Scripts (aws.typepad.com) Report memory utilization to CloudWatch on Amazon EC2 (james-singh.com)
- I have acquired four Raspberry Pi Model B devices since they were initially released - one of which has the upgraded 512MB RAM that I am so desperately anxious to play with. As such I identified a number of excellent learning projects to start with - some already complete and others pending: Nintendo Game Console replacement (complete), WebIOPi interface (complete), XBMC Media Player (complete). The one I am most anxious for is (more…)
- I write a lot about Amazon Web Services as that is what I am most familiar with but I wanted to post a comparison for contrast. I was actually quite impressed with the competitiveness across services (which included AWS, Google CE, and Windows Azure). Still, I would say hands-down Amazon is the cheapest overall and most businesses are unlikely to disburse their resources across multiple clouds (although that leaves the door open for numerous other discussions I am certain I will entertain at a later date). Google is lacking (more…)
