Alibaba Cloud Server Load Balancer

What Alibaba Cloud Server Load Balancer is

Alibaba Cloud Server Load Balancer is a managed web service that provides Layer 4 and Layer 7 routing, global traffic management and TLS termination. ALB Basic is listed at $0.01 a month, billed hourly as a reference price, and allows 200 backend servers per instance. ALB Standard and ALB WAF-enabled each list 1,000 backend servers per instance; NLB pay-as-you-go lists 400. No prices are listed for those options or for CLB pay-as-you-go, whose description specifies Layer 4 load balancing and pay-as-you-go billing. The service is paid and has no free plan. Backend capacity depends on the selected option, so the 200-server figure applies to ALB Basic rather than to every plan.
