Lately I’ve been reading a lot of information about App Engine; the Google service that looks very promising to me. However, it all seems too good to be true. Call me a negative person, but I would like to know any reasons NOT to use App Engine.
This is programmers related, since I’m asking as in the programmer point of view.
I just want the general “downsides” of App Engine, if any.
No relational database. (No normal ORM …)
Limits on the number of files. (Can’t just upload the 6,000 files in some standard packages…)
Specific VM required. (Depending on your language you may be a non-starter.)
Runtime limits. (Don’t get bogged down.)
SSL only through https://your-app-id.appspot.com (Not directly to your domain.)
Root domains via URL redirection only
I am not criticizing GAE, I’m just listing limitations as the OP asked…
