Google App Engine

Google App Engine allows the running of Java, Python or Go applications locked down in a sandbox on Google's infrastructure. Limits are set to prevent overuse of resources.
== More info ==
=== Database ===
Google App Engine uses a non-relational database system that has basic CRUD (Create, Read, Update and Delete) support, using models and kinds.
=== Uploading ===
Uploading is done using "appcfg", included with the App Engine SDK. appcfg parses app.yaml or the equivalent Java configuration file "appengine-web.xml" and deploys the application to Google.
=== Networking ===
Networking is possible with Google App Engine, but only HTTP requests are supported via urlfetch, which uses Google's HTTP request fetcher (which powers Googlebot). Furthermore, only ports 80, 443-445 and 1024-65535 may be connected to. An example:
from google.appengine.api import urlfetch
def main():
 req = urlfetch.fetch("http://google.wikia.com/wiki/Google_Wiki:Main_Page")
 if req.status_code == 200:
 print req.content
 else:
 print "There was an error fetching the page."
