Introduction to Direct Internet Access
Demand for internet access is on a continual growth path. Organizations are looking for ways to balance access and efficiency while simultaneously controlling costs. The typical architecture used to provide internet access routes traffic from various remote locations on a shared connection back to a data center thereby creating an ever-growing bottleneck.
Configuring Direct Internet Access (DIA) on Cisco's SD-WAN (Software-Defined Wide Area Network) is a solution that aims to lower consumption and provide a better user experience by routing internet access directly to a requested resource rather then routing that traffic through a central hub first.
There are various DIA circuit types, like cable or DSL connections, but regardless of the type there are some common benefits:
Guaranteed bandwidth as a circuit is not shared with other subscribers
Reduced network congestion by routing traffic directly to cloud resources
Strong SLA provided by the vendor
Synchronous upload and download throughput at the purchased speed
Better response times
Regardless of the connection type, the primary goal of direct internet access is to allow customers direct access to cloud resources (such as Office 365) instead of routing that data through a primary data center first.
