Enabling the network-embedded cloud Dec 21st 2012, 19:19 Growth in the number of smartphone and tablet applications deployed in public data-centers, and the rising use of cloud services by enterprises can lead to stretched resources, suboptimized networks and, ultimately, an inferior user-experience. Perhaps now is the time to reshape the cloud. Until now, the networking compo¬nent of cloud infrastructure has been confined primarily to intra-data-center communication. However, there are a number of factors that are driving the development of inter-data-center net¬working. These requirements need to be analyzed to understand the differences in the resource environments of intra- and inter-data-center communication; and the characteristics of data-center traf¬fic patterns throughout the life cycle of a given workload. Network virtualization provides tenants with secure, isolated, elas¬tic network-slices with associated SLA guarantees – in essence, Networking as a Service (NaaS). Cloud orchestration and elastic networking act as the glue that binds computational, storage and networking resources together. To fully adopt the cloud as a central technology, additional network considerations such as bandwidth, latency and privacy need to be addressed. Current VPN technolo¬gy takes these parameters into consid¬eration in the WAN but comprehensive integration into the cloud technology base is lacking. The complete article details Ericsson's vision of the network-embedded cloud and elastic networking. Enabling the network-embedded cloud
