> - Cheap to start At development scale it's essentially free. I host some simple static sites essentially for free too because traffic is low enough that it never comes close to billing. > - As someone mentioned versioning. It works as easy as changing the YAML file. Pro Tip: incorporate this into your deploy scripts with `--version=whatever` to override the setting in app.yaml. Make the value in app.yaml a safe one (e.g. 'development') in case someone new to the team screws up. > - HTTP request 30 seconds. Depends on the scaling you choose. This is the default (automatic scaling), but you can choose manual_scaling (you set the number of instances) or basic_scaling (slightly less configurable than automatic scaling). Both of the alternatives put no limit on time to execute a request. > Datastore is I believe 1mb. Blobstore 50mb. IIRC cloud storge provides unlimited size, and it's pretty easy to write a blob there and reference it in datastore.
