Mitch,
maybe someone with more knowledge about the flexible GAE environment or GCE
can help regarding portability of code and if there are performance
differences.
>From my experience with only the standard GAE environment (Python with
NDB/Datastore, GCS, Task Queue and a few other things), I don't think that
portability is an easy task here. Of course, you can use WSGI, Django,
webapp2 and so on, some standard features are conveniently wrapped (e.g.
logging, GCS as file I/O, sockets) etc. But at the end of the day, GAE is a
PaaS offering with nicely integrated services ready-to-go and easy to
manage and scale ("batteries included"), and as such it is probably less
portable than IaaS offerings. The NDB library for Datastore comes to my
mind. I guess, you could use equivalent clients in the Cloud Python library
to achieve a more portable solution for all of the features coming with the
Standard environment, but then it might make more sense to pick the
flexible GAE environment or even GCE. Each of the options come with their
own pros and cons, really depends on your requirements and
priorities/constraints.
Regarding the two GCS libraries specifically, I'm afraid they have
different APIs.
