ULB.LoadBalancer
Element Description
The ULB.LoadBalancer element can be used to deploy a shared load balancer resource object at the PaaS layer. By creating such an object, you can provide a unified entry address for a group of containerized applications with the same functions, and distribute requests in load balancing mode to backend container applications. Shared load balancers are applicable to web services with high access traffic. They forward the requests based on domain names or URLs, making request routing more flexible. Compared with classic load balancers, shared load balancers provide stronger HTTP and HTTPS forwarding capabilities, and better forwarding performance and stability.
