My understanding is that Google started moving all the projects from
SQL-based solutions to Bigtable solutions years ago. From an internal
prospective, GAE would just be a new higher-level alternative to using
BigTable directly.

There's Google Front End, parts of Google Apps, the anti-bot software
that occasionally causes problems... but it's more than just the
software that important here. We know they can scale the hardware if
necessary too. The fact that the datastore runs on BigTable which runs
on GFS mean that we know that it can grow to an enormous size. They
should be able scale infrastructure far beyond what GAE runs on now
because they've already done it with similar technology.
This doesn't mean GAE will be able to scale, that something new or
different won't be a bottleneck that other Google services didn't
have. However, I think a lot of Google's confidence that GAE can
scale comes the fact it is built on technology that has proven it can.
Personally, I'd be more concerned about reliabilty than scalabity.
Not all of Google service's have a great track record in that respect.
