Alibaba Cloud Server Load Balancer

What Alibaba Cloud Server Load Balancer is

Alibaba Cloud Server Load Balancer is a managed web service offering Layer 4 and Layer 7 routing, global traffic management and TLS termination. The listed plans include ALB Basic, ALB Standard, ALB WAF-enabled, NLB pay-as-you-go and CLB pay-as-you-go. ALB Basic is listed at $0.01 a month, billed hourly as a reference price, with a limit of 200 backend servers per instance. ALB Standard and ALB WAF-enabled each list 1,000 backend servers per instance, while NLB pay-as-you-go lists 400. No prices are listed for those three plans or for CLB pay-as-you-go, whose plan description specifies Layer 4 load balancing and pay-as-you-go billing. The product is web-based, paid and has no free plan. Its listed backend limits vary by plan, so the 200-backend limit shown for ALB Basic should not be taken as the limit for every option. The higher listed limits belong to other ALB and NLB plans.
