Research and decide on hosting

[thekaveman]

Background

The eligibility server needs to be hosted somewhere such that it can receive and respond to HTTP requests from a Benefits client instance.

The owner of the hosting environment is not as important as are the agreement(s) in place that allow for sharing of (hashed) Courtesy Card data with said hosting environment.

Decision needed

The main decision point for hosting of the Eligibility Server:

Will the server be co-located with the Benefits client app deployment (CDT/Azure), or will the server be deployed to a new environment?

Co-locating with Benefits client app

The server would just be another Azure App Service.

• Simplest approach, no new cloud accounts / environments to build out
• Reuse deployment strategy from Benefits app
• Need CDT hosting contract signed
• Need CDT approval to store hashed data

Deploy in a new cloud environment

• Adds 1-2 weeks of build/configure time
• Compiler would set this up and manage it (likely GCP, Google Cloud Endpoints looks like one option)
• Could also setup Azure on behalf of MST
• Should probably have agreement between Compiler <> MST
