Open source, content management and the cloud [6/27/11]
Today's web applications face very real challenges to deployment. Websites are incredibly content rich, highly dynamic, and subject to massive swings in load because of anything from content gone viral to the death of a celebrity.
Putting a CMS in the cloud addresses the scalability issue--at least, in theory. The cloud must be optimized for the application to get its full benefit. It doesn't matter that three servers are ready to catch extra traffic if they're not configured to do so. Further, a cloud platform that's not configured to match the CMS's particular needs will have to work much harder than it needs to, resulting in higher loads than is really needed to serve the traffic. For example, it makes sense to cache static content: But will the cloud be able to tell the difference between a user who's signed into the application (and therefore receives dynamic content) and one who isn't?
