When to use AWS

I just moved all of my personal hosting off of AWS recently. The primary reason was cost. AWS is expensive especially when your requirements are static.  

For example, your application needs 5 servers with an elastic load balancer plus a multi-zone RDS MySQL instance, the minimum you'll pay per month is north of $250 for fairly low powered VM's.  Even if you use reserved instances you're average monthly cost will still be around $200.

By switching to a more standard VM hosting company, you can easily get your average monthly cost to around $100 (or even less if you don't need a lot of CPU's).

Personally, I switched to Linode.  I found their offerings to suit my needs and I'm now saving 66% per month.  What am I losing? Practically speaking, nothing. Hypothetically I'm losing a lot of flexibility that AWS offers.  AWS has robust support for API management of hardware, auto-scaling, automated RDS backups and a lot more obviously.  But my requirements are pretty static, so I am comfortable with the trade-off.  

Amazon is doing great things in this space and releasing some great technologies.  In doing so they are creating feature/platform lock-in with early stage technology companies.   Amazon is doing with AWS what Apple is doing with iOS/Mac.  By making the switching cost so high Amazon is ensuring the long term viability of their business.

I love AWS and I will continue to use it for new projects where the requirements are a lot more fluid.  Once the project reaches a point where the requirements are set, I'll then deploy it to another hosting provider.  

PHP Library for Telemetry App

This weekend I had a project that required me to create a live dashboard. I found Telemetry (http://telemetryapp.com) and it looked perfect for what I needed. You simply submit new data for the dashboard via their API. They have clients for Mac, Windows, Mobile and Web to view the dashboard. Unfortunately they only had a Ruby Gem to interact with their API. I had a requirement that it needed to be in PHP, so I was on my own.

Over the course of the weekend I built a fully-functional library for Telemetry in PHP and it supports all of their different data flows. I put it up on GitHub so others could use it.
