The Linux Foundation is home to a lot of interesting projects. A lot of these are projects started by private companies, but moved over to the Linux Foundation to help foster a more active community and development. Keith Townsend runs down three interesting ones for IT architecture. One that he saw at Networking Field Day last week was PNDA, which is a big data analytics project that came originally from Cisco. PNDA is designed to work across data centers, a scale out approach to big data. The Data Plane Development Kit came out of Intel, and helps improve networking performance on commodity hardware. Finally, he introduces Open vSwitch, which came from VMware by way of Nicira.
