Overview

Service Overview

Cloud WAN is a service that provides network connectivity between Samsung Cloud Platform global regions and customer locations. This product provides services based on network traffic usage and offers 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 site, the following settings are required in the user Console. First, create the customer’s virtual backbone Cloud WAN Network. Next, select the access location (Access Location), service level, contract period, etc., and create a segment that matches the intended use. When you connect an attachment to a Segment in the relevant region or customer location, the backbone network between that SCP region and the customer locations is established, allowing them to communicate with each other.

Provided features

Cloud WAN provides the following features.

• Rapid Backbone Network Setup: Customers using Samsung Cloud Platform can select the desired site locations, create a virtual global backbone network, and configure a fast and secure cloud network between Samsung Cloud Platform regions and customer sites, as well as among customer sites.

• Provide various network Edge connection types: By offering various Edge types that can connect to Cloud WAN, Samsung Cloud Platform Compute resources can be conveniently connected via Transit Gateway, the customer’s on-premises dedicated line via Site Connect, and the customer’s on-premises local internet VPN via Site VPN.

• Cost optimization through multi-path selection feature: Unlike traditional backbone network line services that are based on line bandwidth, we charge only for the actual usage in the segments the customer selects, and we offer transmission path options (Gold/Silver) based on traffic characteristics, enabling more efficient line cost management.
• Service Level-Based Operations Management: Customers can select the utilization type of the Cloud WAN backbone transport network, provided features, monitoring, fault management, and technical support level, and receive differentiated network operations management services according to the chosen service level.
