Trying Google AppEngine

I finally took some time to try Google AppEngine. It used to be easy to find free PHP hosting around 2000. It became a rarity. So writing small experiments for free on the web was difficult. Experiments are back thanks to Google with their AppEngine. Many aspects of it are quite interesting and show where they focus.

First it is all Python. It makes sense as I believe Guido v Rossum, Python creator, works for Google. Some people believe in a future Java application hosting. I don’t see any reason why it could not become a reality. Making something like AppEngine is a big task, changing implementation language is not. In the meantime, it is not an excuse not to try it, as the Python standard library is fairly rich and Google provides additional libraries on top of it.

AppEngine offers the basic bricks for building web apps:

With such a list of libraries, one can easily imagine the server side of future apps for Android running on AppEngine.

The way code updates are pushed to the google servers is a bit reminiscent of Java web application deployment. However it is done with much finer granularity (file).

Overall I am happy with AppEngine. Yes it is similar to old PHP hosting, but it adds a lot of value by bringing few easy to use libraries, and natural integration with Google infrastructure. Compared to a PHP hosting, I think the biggest improvement is the database (dev use and admin use). For the dev it is integrated to the code. For the admin, it can be done transparently on the web. The most interesting is that it’s FREE.
