<http://jaiku.jaiku.com/presence/c4c55f7941d0448c9b376e606f330145>It's good to think ahead, and we'd love to approach the challenge of scaling something on App Engine that's as big as Google itself. App Engine's non-relational datastore is built on top of BigTable, a distributed persistence mechanism. Both Twitter and Facebook are known to use similar mechanisms for much of their data. I want to say, yes, it is definitely possible to build similar applications on App Engine. It's better if you are starting from scratch, even, as both those companies have dedicated ops folks and built their own deployment, versioning, staging and rollback tools - building on App Engine means you invest a lot less in this area. App Engine's pricing is also as competitive as it gets. You don't pay for what you don't use, and this will lead to significant cost savings as you grow.
