Strengths
High Performance
A single CLB cluster (not just one instance) can handle hundreds of millions of concurrent connections and process millions of data packets per second. This capability makes it ideal for supporting high-traffic applications such as e-commerce websites, social media platforms, and gaming services with over 10 million daily page views.
High Availability
CLB utilizes a cluster-based deployment to ensure an uptime of up to 99.95%. Even in extreme scenarios where only one CLB physical server is operational, it can still support tens of millions of concurrent connections. The cluster system automatically removes faulty instances and retains healthy ones to ensure continuous operation of the backend servers.
High Elasticity
The CLB cluster dynamically adjusts the application's service capacity based on the business load. It works seamlessly with Auto Scaling to automatically add or remove CVM instances as needed. With real-time monitoring and precise billing, CLB eliminates the need for manual intervention, making it easier to allocate resources efficiently and avoid over-provisioning.
High Security and Stability
With its integration of the BGP Anti-DDoS system, CLB can defend against a wide range of network threats, including DDoS and web intrusion attacks. It swiftly filters out malicious traffic, preventing service interruptions. Additionally, the built-in synproxy anti-attack mechanism protects backend CVM instances from attacks before the Anti-DDoS system is activated, further strengthening data security and system stability.
CLB enforces strict traffic isolation for each tenant and provides proactive DDoS attack protection. Public network CLB automatically includes Anti-DDoS Basic. For enhanced security, CLB also supports Anti-DDoS Pro, Anti-DDoS Advanced, WAF, and other security services to safeguard your applications.
Cost Efficiency
CLB removes the need for extra investments in load balancing hardware and reduces the time spent on operational tasks, helping you save up to 99% on both hardware and labor costs. It also offers flexible billing options, allowing you to choose the best plan based on your requirements.
