OpenStack Cascading report as of July 2019
Motivation
Research possibility and one particular solution for
- Reducing OpenStack blast radius
- General OpenStack scalability question
by looking into OpenStack Cascading solution/prototype.
OpenStack Cascading
This looks like a prototype for aggregating multiple small OpenStack clouds. There are two versions:
- original Cascading PoC presented in 2014-2015
- v2 communicated to OpenStack community during 2016-2017
Now it looks stale and abandoned with no recent commits, new contributors, fresh presentation etc.
OpenStack Cascading solution
By the OpenStack community request initial stateful Cascading solution was split into 3 different efforts:
- Trio2o (API gateway)
- Tricircle (multi-pod networking on top of Neutron)
- Jacket (Cross cloud deployment, Cloud Burst - non-existent effectively)
