In the present era of technology when Information Technology has become the provider of real business solutions, it has become necessary for the organizations to house their resources in a public or private cloud platform, maintained in-house or by a service provider, and made it available on demand. Therefore, with the changing patterns and IT requirements now the SD-WAN (Software-Defined WAN) approach is being used commonly which is unlike traditional router-centric WAN architecture and has been designed in such a way that it fully supports applications hosted in on-premises data centers, public or private clouds, and SaaS services. It is a much-upgraded version of WAN that mostly consists of a combination of public and leased lines that were never designed for the cloud and does not support it. Consequently, we can say that SD-WAN has replaced traditional WAN and is coping well with the present scenario requirements of a cloud network. Having said that, let’s check out what are its benefits.
Advantages of SD-WAN over traditional WAN
SD-WAN is a new network architecture that is a solution to current IT needs. For multisite deployments, this approach to network connectivity can cut operational costs and enhance resource utilization. Network administrators can maintain high levels of performance for key applications without compromising security or data privacy by better utilizing the bandwidth. Its other benefits include:
Moreover, SD-WAN gives the WAN additional agility and speed of provisioning while lowering its total cost. Improved application performance enhances business productivity, customer satisfaction, and profits. Consistent security lowers the risk to the company. Thus, we can say that the capabilities and definitions of SD-WAN solutions will evolve over time as new technologies emerge which is why it is changing the definition of WAN.
