Data Center SDN Delivering Rich Network Services in a Public Cloud
Data Center SDN
Scenario
• Customer – A large public cloud provider use case
• Technology Stack – OpenStack based IaaS services – Cisco ACI network fabric with APIC SDN Controller
• Challenge – Provide differentiated network services to an IaaS customer – Allow flexible composition of services – Enable simultaneous services from multiple vendors
Data Center SDN
Solution • OpenStack GBP for
– Declarative application design and network consumption – Service agnostic lifecycle and configuration model for network services – Service agnostic insertion and chaining/composition model for network services – Adaptability and Automation of network services
• Multiple network services and orchestration solutions including – One Convergence Service Controller
• Life cycle management, Configuration, Chaining • Open source & Commercial network services – LB, FW, VPN, IDS/IPS
– Avi Networks Application Delivery and Inline Analytics • L4-L7 SDN Architecture with centralized Avi Controller and Distributed Data Plane
– Cisco ASAv FW and CSR VPN – Pre-existing Neutron services such as LBaaS
• Service profiles to allow – Tailoring of network service capabilities/rendering by operators – Tailoring of network service UI by service vendors
