SDN networks set cloud apart from the old data center

Grazed from TechTarget. Author: Pankaj Shroff.

SDN networks arose from a demand for connectivity that current switches, routers, network protocols and segmentation tools could not satisfy. Cloud-ready data centers enable an always-on and available-anywhere world of information and productivity. The cloud computing model delivers efficiency and value with economies of scale by pooling compute, storage and networking resources, distributing them where they are most needed, maximizing their use across multiple groups and abstracting away the underlying physical infrastructure.

Some of the biggest inefficiencies and costs of traditional networks arise from tedious, manual configuration and management, performance bottlenecks, connectivity and bandwidth costs, lack of service agility and threats to security. To fully realize the benefits offered by cloud computing, IT teams must overcome networking challenges with virtualization…

Much like servers, network infrastructure can be virtualized so that workloads and data sets dynamically and automatically move between the distributed and heterogeneous cloud server and storage pools. This set of technologies is collectively called software-defined networking (SDN)…
