Cross-regional Secure Acceleration (Oversea Sites)

The Cross-MLC-border acceleration function leverages EdgeOne's global nodes, offering cross-regional secure acceleration solutions for service providers.

Background Introduction

A certain Web service is deployed overseas and provides services to the public through www.example.us (overseas site). It is temporarily unable to be hosted on servers within the Chinese Mainland due to its overseas location. This poses challenges for the service as its main customer base is located in the Chinese Mainland, resulting in network issues such as delays, jitter, packet loss, and the risk of interruptions. To optimize the user experience for Chinese Mainland users, EdgeOne provides the Cross-MLC-border acceleration function, which leverages the Hong Kong access point and Tencent Cloud acceleration network to effectively solve the problems faced by cross-regional services.
