Which type of service provider is responsible for secure, private connections between data centers, access regions, and cloud providers in Cisco SD-WAN Multi-Region Fabric?

Middle-mile network providers are responsible for interconnecting distributed data centers, access regions, and cloud providers with secure, private, and often high-bandwidth connections, forming the backbone of the Multi-Region Fabric. They bridge the gap between local access and the core network infrastructure.

Last-mile network providers are responsible for connecting the end-user or branch office to the nearest service provider point of presence, focusing on local access.
