According to Prasanna, developers and enterprises can get more innovative, state-of-the-art, and high-performance software infrastructure from open source projects that have replicated some of Google's best ideas, like Hadoop and MongoDB, than by using Google's software infrastructure itself. Combining individual best-of-breed software building blocks into a cloud platform as a service environment that offers the functionality of Google App Engine requires enterprises to do a lot more work than simply using Google App Engine.
Another alternative is to consider a vendor whose business is tied to the success, or failure, of the cloud platform as a service offering. For example, Salesforce.com, EMC VMware, Red Hat, Microsoft, and IBM (to name a few vendors) offer environments designed and built for third-party enterprise use.
Keep these considerations in mind while evaluating Google App Engine -- or any cloud platform-as-a-service offering for enterprise use.
