Weather China is the key Internet portal, from which CMA provides meteorological information to the public. In order to meet the requirements of growing load traffic, availability, and user experience, we established a comprehensive monitoring system which monitors various aspects including user experience, availability, website visits, and traffic, network, information security, operating systems, and applications. For many complex business scenarios,we present a set of load control methods aiming at those aspects, especially user experience, availability, cost and security. Based on the monitoring system and control methods, we build a flexible website architecture with CDN and multiple source data centers, which strengthens the capabilities in access experience, availability, bandwidth capacity, security, cost, and operational characteristics.
