a cloud computing platform as a service (PAAS) for
developing and hosting web applications in Google-
managed data centers
Applications are sandboxed and run across
multiple servers
offers automatic scaling for web applications—as
the number of requests increases for an application
App Engine automatically allocates more resources
for the web application to handle the additional
demand
