The document discusses datacenter transformations and proactive datacenter solutions. It covers topics like tenant vs multitenant architectures, scalability, SDN, cloud services, legacy datacenter layers for network, services, compute, storage and management. It then focuses on SDN and provides examples of SDN solutions like OpenStack, OpenFlow protocol, VXLAN, ACI, and how ACI and OpenStack can integrate. It concludes by thanking the audience.

OpenFlowProtocol
The ONF is a non-profit industry consortium that is leading the advancement of SDN and standardizing critical elements of the SDN architecture such as the OpenFlow™ protocol, which structures communication between the control and data planes of supported network devices.
OpenFlowis the first standard interface designed specifically for SDN, providing high-performance, granular traffic control across multiple vendors’ network devices.
