Policy-Based Web Load Balancing System (ASPA WebLoadBalancer)

One of the challenges that high-traffic sites or web applications face is the lack of computing power of existing hardware to produce web content in high transaction numbers. To solve this problem, usually several different hardware serve multiple redundant versions of that site or application. In this case, either a separate name must be considered for each of them, or each of them can be accessed with separate addresses, or the DNS service provider intelligently divides different users among these versions. The first and second solutions usually do not lead to proportional load distribution among those versions due to user choice, and the third solution usually does not have the necessary efficiency because the DNS service provider is not aware of the nature of requests and the current state of service providers. Another solution is to use a web load balancer, which is usually provided by a web service provider using the reverse proxy model. ASPA WebLoadBalancer system is a very powerful load balancing system that uses reverse proxy to provide this capability.
