Finally, lets consider the Open Source movement as a separate part of the cloud. The reason for separating it out is that really it’s all about program code and the cloud itself is a downstream thing:

  • Open Source Web Engines (aaS): The software ecosystem first became of age (imho) with Firefox and its large population of plug-ins. Now we can add Wordpress, Drupal and Joomla, all of them web engines that also provide a wealth of plug-ins that truly qualify as an ecosystem. These products, and many others, are usually available ready loaded on any web hosting site. Associated web sites give you access to the plug-ins.
  • Program Code (aaS): There are hundreds of thousands of projects on SourceForge, all containing free source code (free as long as you abide by the associated license) that you can download and use. It’s a shared resource that is used by many developers to cut development times, and it may not be intended as an open code library, but it is undoubtedly used as one by some programmers.

If we look at the whole picture here (I doubt I’ve included everything), it’s clear that the IT industry has become very “cloudy”. Also, irrespective of the success of any particular company I’ve mentioned, it’s hard to imagine that these different categories of cloud activity will not all continue to grow. I don’t even think that anyone disputes that all the movement is into the cloud. What is not clear is what it will look like when the full migration has occurred.
