Cisco SD-WAN is a Wide Area Network overlay architecture that applies the principles of Software-Defined Networking into the traditional WAN.

The traditional WAN (wide-area network) function was to connect users at the branch or campus to applications hosted on servers in the data center. WANs are not ready for the unprecedented explosion of WAN traffic that cloud adoption brings. That traffic causes management complexity, application-performance unpredictability, and data vulnerability.

Cisco SD-WAN addresses the current IT challenges. It is designed to meet the needs of modern enterprise applications and the rapidly growing security requirements.

Cisco SDWAN is a solution that allows user to quickly and seamlessly establish an overlay fabric to connect an enterprise’s data centers, branch and campus locations, as well as colocation facilities in order to improve the network’s speed, security, and efficiency.

There are multiple, controller deployment options available for customers. Controllers can be deployed On-premises in the company's data centers on a private cloud built with ESXi or KVM hypervisors or in a public cloud such as AWS or Microdoft Azure.

This course is intended to provide design and deployment guidance to onboard Cisco SD-WAN controllers and covers the process of installing the SD-WAN controller software images on a VMWare ESXI instance and establishing the transport and management networks for the three controllers to communicate.

we will also ensure that each controller has a valid certificate installed.
