As a relatively young and highly active Openstack project, Neutron has experienced explosive development and growth over the last couple of years. With growth has come growing pains, where developers and operators alike have faced challenges in achieving reliable service deployments at scale. As a developer and operator, HP Public Cloud faced many of these same challenges. In this talk, we will discuss specific reliability, performance and scalability issues faced in our deployment of Neutron, issues that spanned from the Neutron server to the agents on the compute servers to the DHCP and L3 agents and the metadata proxy. We will share the results of our experiences, the lessons learned and the resulting fixes and enhancements to the Openstack Neutron code base.
