Virtual Routers on Compute Nodes - an (Not So) Irrational Decision?
Learn the production pros and cons of operating Neutron legacy and HA routers on compute nodes in your production cloud. Not ready for DVR or third-party network overhauls? Virtual router network “hot spots” got you down? Large virtual router failure domains keeping you up late at night? Neutron reference architectures not providing a scalable routing solution? If you answered yes to any of these questions then this talk is for you.
What can I expect to learn?
- Real world performance and system resource use of virtual routers
- Neutron and underlay network traffic patterns, including encapsulation effects and "tromboning"
- Consideration of the impact of Open vSwitch flows on this methodology
- Required tuning of L3 Agents and message queueing
- Ensuring "good neighbor" effects between resources shared for networking and compute
- Discussion of why and when this type of implementation might be a mistake
