Traditional WAN has following limitations:
Escalating cost due to the use of MPLS technology, including the managing price of MPLS network and remote location
Addition of a new site or changes in the existing one requires an exhausting manual process
Fully dependency on the internet service provider
Compromised Application Visibility and Security
Complicated and Static Network Configuration Management
The complete network failure, since, the backup link has come from the single ISP
This model that included improper usage of bandwidth and degraded productivity has driven the urge of a newer intelligent Software-Defined model for the WAN, i.e. the SD-WAN. And, these are the reasons that SD-WAN technology replaces MPLS. With this SDN approach come into being, a myriad of changes happens.
So, let us have a quick glance over those good changes with SD-WAN.
Transformations with SD-WAN
Separates the data plane and the control plane of the network
Centralized Orchestration, Control, and Zero Touch Provisioning (ZTP)
Deployed in branch offices and data centers in an organized way
Associating the cloud technology and mobile computing
Monetary savings come from infrastructure and transport cost
Improving Operational Efficiencies
Enabling agility and streamlining
End-to-End encryption over the entire network
These are some of the goods of
SD-WAN technology when it is added to your WAN network.
No doubt, software-defined WAN offers an assortment of perks not only to the organizations but also gives a pavement to the next technology.
