Cloud computing is internet-based computing in which large groups of remote servers are networked to allow the centralized data storage, and online access to computer services or resources. Clouds can be classified as public, private or hybrid. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
While heightened activity is not likely to deliver widespread SDN and NFV deployments in the next 12-to-24 months, it will certainly accelerate adoption in that key two-to-five year timeframe. Read more »
A 2014 Gigaom Research survey found that there are many benefits to having SDN and NFV deployments in the enterprise, including lower cost and the ability to simplify network deployments. Read more »
Risks, including security and the likelihood of failure, were cited as the top barriers to wider SDN deployment in the enterprise, according to a 2014 Gigaom Research survey. Read more »
For the enterprise, the WAN (31 percent), data center (26 percent), and WLAN (17 percent) are the highest priority targets for SDN deployments. Read more »
Open source has indeed become mainstream, representing what IT users have come to expect from open source software solutions over the last decade: maturity, robustness and reliability. Read more »
