This is a Q1 goal:
- Package and puppetize a deployable basic ATS config
- Deploy 4-node test clusters running ATS in eqiad + codfw
- Deploy code/configuration for basic application-layer request routing from these clusters (keeping in mind this will be a single shared backend cluster for all of the currently-separated Varnish clusters)
Not in scope:
- Full request mangling matching current VCL
- Solving scalability / design issues related to chashing and inter-node/cluster communication, etc
- Purging
