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

An Interim Solution for Elastic Beanstalk Deployment Failures

I ran into a problem recently that stumped both myself and the AWS Support team – in face I still have two open support tickets that AWS is investigating internally.

Four Scalability Obstacles on AWS

With Amazon Web Services’ announcement yesterday that CloudFront now supports POST, PUT, DELETE, OPTIONS, and PATCH requests, and a GIGAOM post, “Five features Amazon Web Services must fix”, I was prompted to complete an idea I had noted a couple of months back.

Amazon Steps Up CloudFront, Adds POST Requests – What It Means

Developers have endured a love/hate relationship with Amazon CloudFront since its inception.

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, … Continue reading

Building a Private AWS-compatible Cloud for $400

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

Eucalyptus Cloud on Ubuntu 13.04 SE

I’ll be posting a follow-up after I have the opportunity to try some things out but I’m working on a small development environment now with Ubuntu 13.04 and Eucalyptus. My challenge at the moment is the servers we are using – primarily that I cannot begin with FastStart because the servers do not have DVD … Continue reading

Comparative Analysis: Drupal versus Django

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

Cube 3D 2nd Generation Printer Review & Tips

This post might be a bit outside of my usual scope of IT Operations but certainly inline with the developer/toying mindset that lends itself to my writing about things like the Raspberry Pi. If you like your toys as much as I do than you no doubt are already familiar with the recent announcement that … Continue reading
