Sun takes on the problem of interoperability and portability of applications in a world where there will be many many clouds. At the roll out of the Sun Cloud, key executives explain Sun's implementation of Open Cloud API's and what they see as a pressing need for management tools that will allow some standardization across clouds.

Sun's Open Cloud API plan is a clean reuse of existing Open Web API's.

"..... The underpinning of the Open Cloud Platform that Sun will be pitching to developers is a set of cloud APIs, the creation of which is focused under Project Kenai and which has been released under a Community Commons open source license. Sun wants lots of feedback on the APIs and wants these APIs to become a standard too, hence the open license. These APIs describes how virtual elements in a cloud are created, started, stopped, and hibernated using HTTP commands such as GET, PUT, and POST...."

"...... The upshot is that these APIs will allow programmatic access to virtual infrastructure from Java, PHP, Python, and Ruby and that means system admins can script how virtual resources are deployed. The APIs, as co-creator Tim Bray explains in his blog, are written in JavaScript Object Notation (JSON), not XML. The Q-Layer software is a graphical representation of what is going on down in the APIs, and you can moving virtual resources into the cloud with a click of a mouse using the dashboard or programmatically using the APIs from those four programming languages listed above. (PHP support is not yet available, but will be)....."

I can see why Sun picked those four languages first. Can I assume that with a bit of work, this API will be usable from any language with a C "foreign function interface", such as Perl, Common Lisp, Bourne shell, Squeak Smalltalk, and others that your server application might be written in?

I read this comment that largely answers my question at: http://www.tbray.org/ongoing/When/200x/2009/03/16/Sun-Cloud "So right now JSON out of a shell tool is not so good. More things like this will create pressure for development of tools to change that, but years of widespread XML/HTML deployment have only produced a few oddly maintained tools. Perhaps that's because you can scrape quite a bit of the web with a couple sed passes, and if I were to have to deal with the mentioned tools, that's probably the route I'd take." (seth w. klein) In other words, with a bit of work, _anything_ that can talk text over HTTP can do this with a bit of work, but an object-oriented is likely to be more at home with JSON (JavaScript Object Notation)
