SD-WAN technology enables enterprises to make their network efficient and dynamic when it comes to consuming network resources.
FREMONT, CA: Times have changed, and enterprises are leveraging the cloud and subscribing to software-as-a-service (SaaS). A Software-defined Wide Area Network is a virtual WAN that enables enterprises to leverage transport services to connect users to applications. SD-WAN leverages a centralized control function to securely and intelligently direct traffic through the WAN. This increases application performance and offers a high-quality user experience, resulting in increased business productivity, agility, and reduced costs for IT. Read on to know more.
The traditional WAN is no longer suitable because backhauling traffic – including that destined to the cloud gives latency and impairs application performance. SD-WAN offers WAN simplification, lower costs, bandwidth efficiency, and an easy on-ramp to the cloud with significant application performance, particularly for critical applications, without sacrificing security and data privacy.
SD-WAN technology deployment varies depending on the SD-WAN vendor. Still, a core feature of SD-WAN is that it allows customers to create a single network infrastructure that includes several connection types, like multiprotocol label switching (MPLS), broadband, or cellular connections. Customers can benefit from SD-WAN to depend on expensive, private MPLS connections less and use cheaper, public connections for less sensitive data. There are times where SD-WAN and MPLS are provided together from a vendor or service provider.
SD-WAN technology also lets enterprises’ traffic change transports, the cable or wireless infrastructure connecting the branch office and data centers. The transports being leveraged can be mixed based on bandwidth availability. And when remote locations have to be added to the network, the connections can be spun up quickly and seamlessly than with hardware-based networks. SD-WANs advantage organizations by removing expensive routing hardware and instead of providing connectivity and services from a single location, like a headquarters or the cloud. It also has the advantage of increased flexibility, enabling organizations to scale connectivity up and down for peak-and-valley demand.
