Overview

After some recent discussions with members of the Google Crisis Response Team, we are looking at what is required to get Sahana Eden working on the Google App Engine (GAE).

We are investigating what are the current issues with getting Sahana Eden running on GAE, and what efforts may be required to ensure that Eden can be successfully deployed.

Issues

Potential Issues

These are issues that have been discussed as possibly/likely, but have not yet been tested/confirmed.

• GAE bigtables doesn't support db joins
• Some complex Python libraries (particularly those that interface with C executables) may need to be installed by Google to work e.g. ​LibXML and ​Shapely

Known/Confirmed Issues

These are issues that have actually been tested/confirmed.

Actions Required

• Request access to ​Google Appe Engine Business Preview to test Sahana Eden with hosted SQL and SSL.
