User:RobertKaye/3Scale Non Rate Limited Web Service

Motivation, goals and measuring success

The motivations to create a non-rate limited web service are:

• Allow us to keep track of commercial customers and charge for commercial access to our web service.
• Give end-users the option to pay for non-rate limited access to our web service so they can tag their music collection faster

The end goal of this project is to create two tiered service of our ws/2 (not ws/1) web service:

• where anonymous web service users get free service given the current limits.
• where people who have signed up with 3scale and have credit in their account get access to our ws/2 web service with no required pauses between requests, but are limited to X concurrent requests.
• where people who have signed up with 3scale, but have run out of credit in their account, simply revert back to the rate limited web service.

We will have succeeded if a developer can:

• Start with an existing application that uses the MB web service version 2
• Sign up for service at the MusicBrainz WS sign-up form hosted at 3scale
• Add the application/developer keys to their application.
• Have their application successfully make non-rate limited requests of the ws/2 web service.
