Investigate provisioning Lambda functions for SQS

[benhohner]

We need SQS to be able create a PATCH or POST to a RESTful API endpoint. This is required for sending data to a Cinchy API. In the future we may be moving away from Basket, and sending data directly to Cinchy. We need a solution in AWS to make a RESTful request.

Initial idea: SQS -> Lambda function

Investigate:

• Possible solutions
• Feasibility
• Rough estimate of how long to implement

[tomusher]

Just a few questions on this:

• How time critical are the messages?
• Do we have an example of the sort of messages that this will be processing?
• Is SQS required in this situation vs buffering messages in the source application and sending directly to Cinchy on a cron?

Whatever the case, the two approaches I'd expect to be most suitable are:

• Lambda to process messages, triggering appropriate API calls.
• Processing messages in a separate application running on Heroku.
