Implementing the right software-defined wide area network (SD-WAN) framework for the organization can help improve network management, decrease hardware costs, increase efficiency, and even enhance security. In this course, you'll explore the differences between traditional, software-defined networking, and a software-defined wide area network (SD-WAN). You'll learn about the advantages, working mechanisms, solution architecture, and primary components of SD-WAN. Next, you'll examine the topologies and deployment models that can be used to design SD-WAN overlays, along with prominent tools and applications that can be used to build, deploy, and maintain SD-WAN. You'll learn how to apply CloudOps in networks to simplify configuring, managing, and delivering the SD-WAN. You'll examine security challenges and best practices for secure deployment of SD-WAN and prominent Cisco SD-WAN architectures that can be implemented in AWS. You'll see approaches that can be used in an SD-WAN to transform complex legacy networks into easy-to-manage and scalable networks. Finally, you'll learn to configure AWS Transit Gateway, AWS-provided Cisco Cloud Services Router 1000V - BYOL, and VMware SD-WAN.
