Enable unprecedented levels of automation and agility with cloud computing solutions.
What is a Wide Area Network (WAN)?
A wide area network, or WAN, connects individual machines or local area networks (LANs) over a long distance. WANs are typically used to connect multiple business locations.
Wide area network definition
A network can be considered to be a wide area network if computers or LANs are connected over a distance of half a mile or more. WANs have traditionally been run over leased, private lines, but can now be fully or partially cloud-based.
Why use a WAN?
WANs allow companies to centralise or outsource IT infrastructure rather than house servers at every business location. Even in the age of cloud computing, WANs are still a very important part of the IT strategy for most businesses, largely because they and increase the performance of business-critical applications, cutting downtime and increasing productivity. Software-defined WANs (SD-WANs) take this even further by automatically balancing workloads to maximise cost-efficiencies while optimising applications and traffic across multiple uplinks.
