Connection methods

MethodDescription
Express ConnectConnects your data center to Alibaba Cloud over a dedicated private link, bypassing the public Internet. Set up a connection using one of three options: apply for an exclusive physical connection from an Internet service provider (ISP), use a shared physical connection through an Alibaba Cloud partner, or use an Alibaba Cloud managed service. Because traffic travels over a private internal network, Express Connect delivers higher security, higher reliability, higher speed, and lower latency than an Internet connection. For details, see the Express Connect product page.
