Network virtualization removes the barriers that traditional networks face by providing multi-tenant network scalability and security, flexibility of workload placement and mobility, and elimination of error-prone manual reconfiguration, which are all challenges faced by large-scale cloud operators.
As a result, network virtualization provides many capabilities for software developers to create and deploy web-scale apps or enterprises to create a research and development cloud.
“Nicira’s NVP software enables truly massive leaps in automation and efficiency,” said Carl Perry, Cloud Architect at DreamHost. “NVP decouples network services from hardware, providing unique flexibility for both DreamHost and our customers. By sidestepping the old network paradigm, DreamHost can rapidly build powerful features for our cloud. Network virtualization is a critical component necessary for architecting the next-generation public cloud services. Nicira’s plug-in technology, coupled with the open source Ceph and OpenStack software, is a technically sound recipe for offering our customers real infrastructure-as-a-service.”
DreamHost joins NTT, Rackspace and others using Nicira’s software to reduce costs and accelerate service delivery in data center environments based on OpenStack, which recently announced that 19 companies have joined its OpenStack Foundaction.
NVP is a scalable software system implemented at the network edge and managed by distributed clustered controller architecture. The system forms a thin software layer that treats the physical network as an IP backplane.
This allows the creation of virtual networks that have the same properties and services as physical networks, such as security and QoS policies, L2 reachability, and higher-level service capabilities such as stateful firewalling.
These virtual networks can be created dynamically to support VM mobility anywhere within or between data centers without service disruption or address changes.
Nicira is sponsoring the fifth OpenStack Design Summit & Conference next week at the Hyatt Regency Hotel in San Francisco.
