Multi-Services SD-WAN is a technology designed to reduce the cost of managing networks, improve security, and enhance performance. SD-WAN stands for “Software-Defined Wide Area Network” and is a change from the more traditional forms of WANs. Traditional WANs, such as MPLS (Multiprotocol Label Switching), require cables, routers, and intricate configurations to connect locations, but with SD-WAN, users can rely on any type of connection - wired, wireless, or satellite - to build reliable, secure, and easily manageable networks. Moreover, since SD-WAN is built with software, it is quick and easy to configure and manage the networks. Furthermore, it can be tailored to specific use cases, making it ideal for enterprises with varying needs. It also requires fewer resources to maintain and can be managed centrally, which adds to its popularity and wide usage.
Many organisations and government networks utilise SD-WAN. For example, the Hong Kong Police Force used SD-WAN solutions to create a secure, private network which connects multiple locations and provides fast, reliable communication between officers and support units. Additionally, many hospitals, schools, and other government organisations are also taking advantage of SD-WAN due to its cost-effectiveness and the ability to deploy a secure network quickly.
