With the announcement last night of Google App Engine, it’s now literally possible to build your entire web app on top of Google’s vaunted infrastructure – the BigTable, CPU cycles, and bandwidth – all courtesy Google.
It has already been possible to do that (and more) on top of Amazon’s infrastructure for some time now, and so far, Amazon’s AWS is in the lead. Amazon EC2 and S3 are highly scalable platforms, which provide the advantage of utilizing resources on-demand from an external hosting node as well.
Google App Engine comes with its own limitations, but never-the-less this is Google’s grand entry into consumable cloud computing.
