Operators experience and perspective on SDN with VLANs and L3 Networks

Networking is one of the most challenging aspects to running OpenStack. There exists a lot of  SDN vendor plugins and it is very difficult for customer to recognise what is and is not slideware. We both spend more than 3 years by working and testing different Neutron vendor solutions. We have come to several insights into CPU penalties, Network design issues at scale as well as performance comparisons using different encapsulation techniques.

This presentation will cover architectural and performance characteristics of what a Overlay network is compared to a straight VLAN based environment on a cluster size of 100+ nodes.We will also cover best practices and experience obtained by running a full routable L3 network in a production environment with a high number of security policies enforced at port level.

We would like to share our story about networking reference architecture. Where we started and what led us to this SDN platform.

What can I expect to learn?

How to build production scalable (100+ compute nodes) OpenStack networking.

How to connect legacy (baremetal, non virtualized applications) and a “new” cloud infrastructure.

How to create single networking platform for containers and VMs.

I am member of the Cloud Operations and Infrastructure teams for one of the lead SaaS provider in Finance and human resources management, Workday. My current role as OpenStack user is giving me a different opinion about what OpenStack should integrate and how it can be consumed easier and more scalable for both Service Provider and Entreprise sectors.
