In this talk, we will present the experiences, lessons learnt and challenges of running one of the largest SDN networks using OpenStack and Neutron. eBay Inc has been running Openstack with SDN networks both for internal and production networks. The operational experiences of running production quality workloads will discussed. 

Description of the Presentation
eBay Inc. runs multiple OpenStack deployments in its various data centers. The OpenStack clusters run as availability zones (AZ) and the PaaS layer deploys applications for production facing  workloads in these AZs. Some of the key tenets of the OpenStack cloud at eBay has been to provide agility, resiliency and multi-tenancy for the various properties under eBay Inc., leverage uniform IaaS layer for production, QA and development workloads. The size of the eBay cloud is several thousands of hypervisors in vairous AZ's. 

The OpenStack deployment at eBay uses Neutron for the networking componets with commercial SDN solutions. In this presentation, we present our deployment models, challenges and lessons learnt. The talk will be organized as follows:



  • Overview of the cloud architecture

  • Monitoring



  • Auto remediation of network issues and alerts



  • Challenges

    • Network scale



    • Availability



    • Issues due to security groups



    • Load Balancer challenges



    • IP address management



    • Lessons learnt







  • Future deployment models
