Web server plays a vital role on serving requests from clients. As Internet users grows so fast, the request number increases significantly, thus reducing the overall performance of the web server. One solution is to implement a load balancing system.In this paper, we implement load balancing with Linux Virtual Server to distribute the load to several machines within a cluster. We compared Round Robbin and Least Connection algorithm. The study reveals that load balancing using LVS-NAT can double the throughput output compared to single web server, but less significant on response time and CPU utilization. Implementing LVS-NAT using round robbin algorithm is more robust in optimizing the throughput, CPU utilization, and response time compared to least connection.

Today, web services rapidly increased and are accessed by many users, leading to massive traffic on the Internet. Hence, the web server suffers from this problem, and it becomes challenging to manage the total traffic with growing users. It will be overloaded and show response time and bottleneck, so this massive traffic must be shared among several servers. Therefore, the load balancing technologies and server clusters are potent methods for dealing with server bottlenecks. Load balancing techniques distribute the load among servers in the cluster so that it balances all web servers. The motivation of this paper is to give an overview of the several load balancing techniques used to enhance the efficiency of web servers in terms of response time, throughput, and resource utilization. Different algorithms are addressed by researchers and get good results like the pending job, and IP hash algorithms achieve better performance.

We have designed, developed, and implemented SOAP-based web services in load balancing cluster-based web server and carried out load testing over the system. The roles of web services, such as client, broker, and service provider are segregated among different services. The system is monitored through a load testing tool, Mercury LoadRunner. The recorded system metrics are evaluated to study the overall performance and reliability aspects against different massive level of users. This article presents in detail the system architecture, testing methodology, and recorded system metrics. The statistical analysis is carried out to validate and correlate the overall assessment. This article also provides insights of some aspects of system metrics for deploying web services with segregated roles by using a cluster-based web server. It is observed that service with segregated roles is better than the service with merged roles. As a result, performance and reliability of the proposed system is observed to be better than other generic techniques for such deployment.

Load Balancing Algorithm

The load balancing method based on the Linux server cluster is proposed in large-website construction. The load balancing of server cluster is achieved by SSH framework, Oracle database and Ajax technologies. The load balancing of server cluster method can’t only improve performance, scalability, availability of system and reduce the execution time of multi-tasking but also eliminates network bottlenecks and improve the flexibility and reliability of the network. In order to verify the validity of the algorithm, large number of experimental data is used in the experiment. We propose a method of load balancing algorithm is compared with the traditional non-load-balancing algorithm for CPU utilization and system response time in the experiments. The experimental results show that the load balancing technology can reduce system response time and CPU utilization of server.

Load balancing applications introduce delays due to load relocation among various web servers and depend upon the design of balancing algorithms and resources required to share in the large and wide applications. The performance of web servers depends upon the efficient sharing of the resources and it can be evaluated by the overall task completion time of the tasks based on the load balancing algorithm. Each load balancing algorithm introduces delay in the task allocation among the web servers, but still improved the performance of web servers dynamically. As a result, the queue-length of web server and average waiting time of tasks decreases with load balancing instants based on zero, deterministic, and random types of delay. In this paper, the effects of delay due to load balancing have been analyzed based on the factors: average queue-length and average waiting time of tasks. In the proposed Ratio Factor Based Delay Model (RFBDM), the above factors are minimized and improved the functioning of the web server system based on the average task completion time of each web server node. Based on the ratio of average task completion time, the average queue-length and average waiting time of the tasks allocated to the web server have been analyzed and simulated with Monte-Carlo simulation. The results of simulation have shown that the effects of delays in terms of average queue-length and average waiting time using proposed model have minimized in comparison to existing delay models of the web servers.

The development of internet technology has many organizations that expanded service website. Initially used single web server that is accessible to everyone through the Internet, but when the number of users that access the web server is very much the traffic load to the web server and the web server anyway. It is necessary for the optimization of web servers to cope with the overload received by the web server when traffic is high. Methodology of this final project research include the study of literature, system design, and testing of the system. Methods from the literature reference books related as well as from several sources the internet. The design of this thesis uses Haproxy and Pound Links as a load balancing web server. The end of this reaserch is testing the network system, where the system will be tested this stage so as to create a web server system that is reliable and safe. The result is a web server system that can be accessed by many user simultaneously rapidly as load balancing Haproxy and Pound Links system which is set up as front-end web server performance so as to create a web server that has performance and high availability.
