Cloud LAN – Data Center useone Efficiency Network success solution

Overview

Given the accelerating reality of cloud transformation, companies incur high costs and administrative difficulties to maintain network connections for IT resources that have not been migrated to the cloud. Cloud LAN – Data Center is a service that builds a private network dedicated to the enterprise using SDDC(Software-Defined Data Center) infrastructure, enabling various uses such as Internet access, integration with the corporate private network, Samsung Cloud Platform and other CSPs, and On‑premises integration. This document explains how to easily build a customer‑dedicated private network between Samsung Cloud Platform ↔ On‑premises using the pre‑established Shared Network Infra through Cloud LAN – Data Center, with a shortened lead time.

Figure 1. Architecture utilizing Cloud LAN – Data Center

1. The user requests the Cloud LAN – Data Center service through the Samsung Cloud Platform Console and creates a vRouter, vSwitch, and vFirewall.
2. The user connects communication between the previously created virtual resources using vCore and vCable through a Service Request in the Samsung Cloud Platform Console.
3. If a connection to equipment in the form of an appliance (such as a security device, server, database, etc.) is required, connect it to the physical port of the vSwitch.
4. To access on-premises resources, connect a dedicated line or an Internet circuit to the physical port of the vRouter.
5. When accessing resources on the Samsung Cloud Platform, apply for Direct Connect/Transit Gateway and connect to the vRouter.

Prerequisite operation

To use Cloud LAN - Data Center, SCP resources must be pre‑connected via Direct Connect or a Transit Gateway uplink request, and on‑premises resources must be pre‑connected via a dedicated line or an internet line.

Use Cases

DR gateway network configuration

By easily building a DR (Disaster Recovery) gateway network at a lower cost across geographically separated data centers, you can ensure not only service failover but also network service continuity in the event of a disaster. Cloud LAN - Data Center can maintain existing configurations and settings such as network security policies, IP scheme, and network protocols required in an On-Premises environment, allowing you to use the same security and network policies you used before when a disaster occurs. It can minimize work interruptions.

Maintaining security through logical network segmentation for client companies

If a separate closed network is required for data and IT resources that need security maintenance, hardware investment and maintenance costs can become excessive. By using Cloud LAN – Data Center, you can implement logical network segmentation and build a closed network that meets security standards.

Constraints

For using Cloud LAN – Data Center, the network that must be prepared in advance can support up to 10 Gbps. (However, if additional capacity is required, consultation is needed.) Datacenter Firewall can currently be used only with Secui and Fortinet. (However, appliance hardware can be accommodated if the customer desires)

Considerations

Firewalls can be calculated based on capacity.
