Application Scenarios

Access to Multiple VPCs Within a Region from an On-premises Data Center

After you connect your on-premises data center to the cloud using Direct Connect, you can use a peering connection to connect the VPC that your on-premises data center is accessing to those in the same region, so that your on-premises data center can access all connected VPCs.

Hybrid Cloud Deployment

Direct Connect allows you to build a hybrid environment for your on-premises data center and leverage the scalability of the cloud to expand the computing capability of your applications.

Application Scenario

Description

Virtual Private Network (VPN)

Connect an on-premises data center to the cloud through an IPsec tunnel.

An encrypted tunnel is used to connect a VPC to an on-premises data center over the Internet. The tunnel features low cost, simple configuration, and ease-of-use. However, the network quality depends on the Internet.

Direct Connect

Connect an on-premises data center to the cloud using a dedicated network connection.

A dedicated connection connects a VPC to an on-premises data center. The connection features low latency, high security, and dedicated use. It is applicable to scenarios that require high network transmission quality and security.
