Google Developer Day, London 2008

Google Developer Day, Google App Engine Presentation
On tuesday I travelled to London to the Google Developer Day. As expected, the event was very well organised.
Mano Marks gave an excellent set of presentation on Google App Engine. You can view them on YouTube.
I went along to see what I can learn about the Google App Engine and specifically to see if it would be possible to move some of the emailcloud administation system to AppEngine. It seems that this is not possible because of the following reasons:
- AppEngine currently only supports python…it will support more in the future but google have not announced a date.
- There is no way to use the service to manipulate a file…so that we can get a file from AWS S3 and then release it to an email user.
- There is a limit of 5m page views a month…this will increase soon…but no date was announced.
- there is a limit of 1Mb per transaction…this is too small
- there is a time limit of 10 seconds for transactions and 4 seconds for external URL calls
- the only viable database system it can use is BigTable (as to use any SQL database you would need to host it externally and then be limited to access by URL, including the 4 second delay).
- no SLA
- EVERYTHING is covered under the Patriot Act
There were more…but I stopped listening after all this.
