First Principles: building a high performance network in the public cloud

http://oracle.com/fprdma In this episode of Oracle's video blog First Principles, we learn how architects at Oracle Cloud Infrastructure (OCI) are using Remote Direct Memory Access (RDMA) to deliver high performance networking with very low latency for customers' most demanding workloads.
