Owner

As a host,
I want to pool Fediversity instances to shared VMs,
so that usage spikes are ameliorated granting users a smoother experience.

implementation notes

ways to achieve this include:

pooling a user's services into VMs shared across their resources (c.f. #339)
pooling a service across different users into a shared VM
- note this comes with security concerns
- performance gains may particularly impact applications prone to resource usage spikes
- may involve use of SRV records
- more on this at vanrein/architecture#1
- challenge: what does this mean for migration (#100) when hosting providers have a shared single instance differing in version?
  - potentially address by initially making a separate instance of the desired version for this, perhaps with the intent to eventually reconcile this into the shared one
~~this may be addressed for now by #327~~
