Service Overview

Cloud WAN is a service that provides network connectivity between Samsung Cloud Platform global regions and customer locations. This offering is based on network traffic usage and provides differentiated operational management services according to the selected service level.

The Cloud WAN service consists of the customer virtual backbone Cloud WAN Network, the Segment that provides logical network segmentation by purpose, and the Attachment that connects Samsung Cloud Platform Compute resources or receives a dedicated line from the customer’s site and connects it to a Segment.

For example, to configure a backbone network connection from a system in a Samsung Cloud Platform region to a customer’s overseas location, the following settings are required in the user console. First, create the customer’s virtual backbone Cloud WAN Network. Next, select the access location, service level, contract period, and other options to create a segment that fits the intended use. Then, by attaching the segment at the region or the customer’s location, the backbone network between the SCP region and the customer locations is connected, enabling communication between them.
