Our workplace is continually evolving. Today, organisations not only have to respond to a fiercely competitive business environment, but also the needs and demands of its employees.
Branch office wide-area network (WAN) connectivity and commercial model is changing. The way that people work, how customers want to be treated, and the need for easier, faster and secured access to data and information are becoming more imperative than before.
Traditionally, organisations have relied on Wide Area Network (WAN), to connect sites over wide geographical areas. This could be a connection between a head office and branches, or from an office to colocation facilities or cloud services. With the increasing use of SaaS, network connectivity has evolved from its original role drastically.
Software-defined WAN (SD-WAN) is a software-enabled approach used to deploy and manage WAN connectivity, allowing connections between different nodes through the benefits of cloud. It puts a secure, virtualised overlay on top of the WAN, allowing central control, so that deployment, configuration and changes can be made through the cloud from one place rather than the sometimes-complex WAN arrangements.
