load balancing

Internet load balancing is a load balancing service that distributes traffic to multiple cloud servers. It can automatically allocate the external service capability of the application among multiple instances, improve the availability of the application system by eliminating single point of failure, and enable you to achieve a higher level of application fault tolerance, so as to seamlessly provide the load balancing capacity required for the distribution of application traffic, and provide you with efficient, stable and safe services.

Product features

Product function

  • Multiple protocol support Rich protocol support to meet your diverse application scenarios
    Specific protocols: four layer load balancing including TCP protocol and UDP protocol, and seven layer load balancing including HTTP protocol and HTTPS protocol are supported.
    Certificate management: centralized certificate management system is provided for the HTTPS protocol to meet the requirements of reliable and secure transmission of users.
  • Multi level disaster recovery guarantee Provide multi-level disaster recovery strategy and highly available user experience
    Health check: regularly detect the operation status of the back-end cloud server. Once the cloud server exception is detected, the traffic will not be forwarded to the abnormal instance to ensure the availability.
    Cluster deployment: cluster deployment is adopted, and sessions between machines are synchronized. Machine failure and cluster maintenance are transparent to users without single point of failure.
  • Intelligent scheduling A variety of scheduling algorithms and forwarding modes to enhance application deployment flexibility
    Scheduling algorithm: support weighted polling and minimum number of connections scheduling algorithm, according to their own needs to select the corresponding algorithm to allocate user traffic.
    Domain name URL forwarding: support traffic scheduling according to different domain names and URLs to improve the flexibility of the application system.
  • Conversation persistence The access requests from the same user within a certain period of time are forwarded to the same server for processing to realize the continuity of user access
    Session persistence based on source IP: four layer (TCP / UDP) load balancing realizes session persistence through IP address.
    Session persistence based on Cookie: seven layer (HTTP / HTTPS) load balancing supports session persistence through cookie.
