Performance Impact of Load Balancers on Server Farms
نویسنده
چکیده
Server Farms have gained popularity for providing scalable and reliable computing / Web services. A load balancer plays a key role in this architecture, serving as a “traffic cop” to direct the requests to suitable servers. Selecting and using the proper load balancer to match the characteristics of the servers will have a significant performance impact. This paper examines some commonly used loadbalancing algorithms for server farms, introduces a performance model as a basis for the analysis, and will show how to select a load balancer to maximize the performance potential of the server farms.

Load balancing using java Aspect Component(Java RMI)
Various types of scheduling algorithms are used by load balancers to determine which backend server to send a request to. Simple algorithms include random choice or round robin. High-performance systems may use multiple layers of load balancing. Load balancing is the process of distributing client request over the set of servers and is a key element of obtaining good performance in distributed ...
متن کاملA General Architecture for Load Balancing in a Distributed-Memory Environment
The goal of load balancing is to assign to each node a number of tasks proportional to its performance. On distributed-memory machines, it is important to take data dependencies into account when distributing tasks, since they have a big impact on the communication requirements of the distributed application. Many load balancers have been proposed that deal with applications with homogeneous ta...
