Access to Multiple VPCs from an On-premises Data Center
After you connect your on-premises data center to the cloud using Direct Connect, you can use Cloud Connect to connect the VPC that your on-premises data center is accessing to those in other regions, 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.

Virtual Private Network (VPN) |
Connect an on-premises data center to the cloud through an IPsec tunnel. |
VPN uses an encrypted communications tunnel to connect a VPC on the cloud to an on-premises data center and sends traffic over the Internet. It is inexpensive, easy to configure, and easy to use. However, VPN connections may be affected by the Internet quality. |

Direct Connect |
Connect an on-premises data center to the cloud using a dedicated network connection. |
Direct Connect provides physical connections between VPCs and data centers. It has the advantages of low latency and is very secure. Direct Connect is a good choice when there are strict requirements on network transmission quality. |
