Product Introduction

Traditional Load Balancer CLB

The original load balancer ULB has been renamed to traditional load balancer CLB, and the performance limit of CLB instances is no longer guaranteed.

The traditional Load Balancer CLB (Classic Load Balancer) is a shared load balancing instance, supporting both packet forwarding and request proxy types, and has basic processing capabilities for layer 4 and layer 7 business packets.

The request proxy type supports HTTP, HTTPS protocols; the packet forwarding type supports TCP and UDP protocols.

CLB Composition

The CLB service is mainly composed of the following three parts:

  • CLB Service Instance: Used to receive traffic and distribute it.
  • Virtual Server (VServer): Listeners, each VServer is a set of front-end port configurations before load balancing.
  • Service Node (RealServer): The real cloud resources that process requests in the back end.
