I continue to read about Google’s App Engine seeking to decide if it is usable as a platform for my current project.
How to handle user authentication and application permissions and roles.
Do I need App Engine? It is sweet on the database side but the platform as a whole seems either difficult to understand or not ready for prime time, reading the developer questions and reports.
Bottom line, I trust Google will fix any problems. The issue is:
a) If I use App Engine then I’m locked into it, or am I?
b) Limits like 1000 records per result set don’t seem an issue now but…. I don’t have a crystal ball.
However, once you taste the App Engine data store interface you don’t ever want to go back to the old relational model ever again.
