JIS is a simple prototype of two services exposing REST(-ish) APIs and sharing information asynchronously over a queue (RabbitMQ) and Amazon S3.

• The backend/ module is shared between photo-service and exif-service. This could be improved by each service having their own backend module to reduce coupling and enable service independance and easier changes.
• The RabbitMQ code is not production grade, but provides an sample implementation of asynchronous communication.
• Uses the notorious MongoDB for storage.
• Photos get fully buffered in memory during uploads/downloads from S3.
• File extensions are disregarded.
• Heavy on the use of optionals and "finals".
