Splitting the Cloud in Three


Last week I attended the Rackspace Customer Event (Lombardi Blueprint is hosted at Rackspace) down on the Riverwalk in San Antonio.  It was a great event and I sat in on some cool talks as well as grabbed some time with several of the Rackspace execs.

Later this week and/or early next week I will be posting the podcasts I did with CEO Lanham Napier, CTO John Engates as well as Mosso co-founder Jonathan Bryce.

One of the talks I sat in on was CTO John Engates’ Cloud Computing presentation.  You can check out the whole presentation here, but the section I wanted to call out was the one that dealt with “The Categories of Cloud Computing.” While not an original construct, it helped me to see it laid out like this:

Application Clouds (SaaS)

  • Ease of use: Low complexity
  • Flexibility: Minimal control
  • Typical Consumers: End users
  • Examples: Mail Trust, Salesfore.com, Blueprint, TurboTax Online, Microsoft Online Services

Platform Clouds (PaaS*)

  • Ease of use: Medium complexity
  • Flexibility: Medium control
  • Typical Consumers: Developers
  • Examples: Rackspace/Mosso Hosting Cloud, Google AppEngine, Force.com, Azure

Infrastructure Clouds (IaaS)

  • Ease of use: High complexity
  • Flexibility: Maximum control
  • Typical Customers: Developers, System Administrators
  • Examples: Rackspace/Mosso Cloud Files, EC2, S3, Microsoft SSDS, FlexiScale, GoGrid

*Not to be confused with PAAS.

While I find these categories helpful now, I’m sure it won’t be long until these divisions go the way of “intranet,” “extranet,” and “internet,” and there’s just one big happy cloud.
