Secure Software-Defined Networks Unlock Digital Information
The classic enterprise network architecture has arrived at a complexity crossroad. As demand for network resources escalates and connections grow between information sources, companies find that traditional approaches to network design and operations don’t measure up to diverse workloads, changing load patterns, increased security postures and new services and capabilities coming from outside the data center. Increasingly, organizations are moving to software-defined networks (SDNs) to provide applications and users with the contextualized, just-in-time, secure information they need.
New demands challenge the network
It is easy to say that, without networks, nothing would work. But the view of networks and their role is changing. By considering networks as core providers of the information, not just data, that flows through them, enterprises can tap into a whole new value proposition.
Businesses are dealing with major transformational shifts across platform, workplace and application domains. As a result, the network’s role is evolving to become more aware of the context for its applications, services and users.
No longer a collection of static appliances and cables, networks — the arteries that supply a company’s vital organs with information — must handle the flow of various types of data, accommodate changing demands, and take remediation actions automatically.
Compute, storage and network requirements have always fluctuated with business needs in real time, but these routine variations are now amplified and broadened by new trends. Beyond the usual cyclical and periodic spikes, enterprises must deal with a whole new range of dynamic network demands.
The digital enterprise, with its focus on greater collaboration with customers and partners and its increasing use of cloud services, is creating high demand for network resources. Organizations have experienced an explosion of mobile devices. Application portfolios have expanded dramatically to serve these devices. A large, geographically distributed workforce and expanded global connectivity are adding to the demand.
In this environment, the modern enterprise network must be gradually enhanced by a set of programmable controls to support added functionality or to improve latency, protection, integration and collaboration. The result is a strong, stretchable fabric that enables integration and connectivity while improving the quality of service and experience.
