Amazon Web Services – What is it and why is it important?

Amazon Web Services is a division of Amazon the bookseller, but this part of the business is devoted solely to infrastructure and internet servers.  These are the building blocks of data centers, the workhorses of the internet.  AWS’s offering of Cloud Computing solutions allows a business to setup or “spinup” in the jargon of cloud computing, new compute resources at will.  Need a small single cpu 32bit ubuntu server with two 20G disks attached?  One command and 30 seconds away, and you can have that!

As we discussed previously, Infrastructure Provisioning has evolved dramatically over the past fifteen years from something took time and cost a lot, to a fast automatic process that it is today with cloud computing.  This has also brought with it a dramatic culture shift in the way that systems administration is being done, from a fairly manual process of physical machines, and software configuration, one that took weeks to setup new services, to a scriptable and automateable process that can then take seconds.

This new realm of cloud computing infrastructure and provisioning is called Infrastructure as a Service or IaaS, and Amazon Web Services is one of the largest providers of such compute resources.  They’re not the only ones of course.  Others include:

  • Rackspace Cloud
  • Joyent
  • GoGrid
  • Terremark
  • 3Tera
  • IBM
  • Microsoft
  • Enomaly
  • AT&T

Cloud Computing is still in it’s infancy, but is growing quickly.   Amazon themselves had a major data center outage in April that we discussed in detail. It sent some hot internet startups into a tailspin!
