Network infrsturcture

 Software-defined Wide Area Network (SD-WAN) is a modern approach to network connectivity that allows organizations to securely and efficiently connect their remote locations, branch offices, and data centers over a wide geographic area.
Traditionally, WANs are designed using proprietary hardware and technologies that are complex and expensive to manage. SD-WAN simplifies the WAN infrastructure by decoupling the network hardware from its management functions and moving them to the cloud.
SD-WAN uses software to centrally manage and control the network by utilizing various available technologies such as virtualization, cloud computing, and software-defined networking (SDN) to provide a more agile and cost-effective solution.
SD-WAN offers various benefits, including improved network agility, increased security, and reduced cost by leveraging cheaper and widely available broadband links. It also enables the use of multiple transport modes, such as MPLS, broadband internet, and LTE, to build a more resilient and flexible network infrastructure.
