| Method | Description |
|---|---|
| Express Connect | Express Connect is the abstraction of the network connection between Alibaba Cloud access points and data centers. You can connect on-premises databases in your data center to DAS by applying for an exclusive physical connection from an Internet service provider (ISP), using a shared physical connection from Alibaba Cloud partners, or using Alibaba Cloud managed services. Express Connect enables the internal networks to be connected without using the Internet. Therefore, compared with traditional Internet connections, Express Connect provides higher security, reliability, and speed as well as lower network latency.
