Pasadena-based Metacloud, the provider of OpenStack-based private cloud deployment services, said it has begun supporting what is called Virtual Extensible LAN (VXLAN) networking support. According to Metacloud, the move eliminates the typical scalability problems found in large cloud computing environments. The company said the move will help boost big data performance of its customers. Metacloud explains the move comes due to requests of clients wanting to migrate their big data environments into Metacloud. Metacloud is venture backed by Silicon Valley Bank, Pelion Ventures, UMC, Canaan Partners, Storm Ventures, and AME Ventures.
