The traffic increasing in the network creates bulk congestion while the bulk transfer of data evolves. Performance evaluation and high availability of servers are important factors to resolve this problem using various cluster based systems. There are several low-cost servers using the load sharing cluster system which are connected to high speed networks, and apply load balancing technique between servers. It offers high computing power and high availability. A distributed website server can provide scalability and flexibility to manage with emergent client demands. Efficiency of a replicated web server system will depend on the way of distributed incoming requests among these replicas. A distributed Web-server architectures schedule client requests among the multiple server nodes in a user-transparent way that affects the scalability and availability. The aim of this paper is the development of a load balancing techniques on distributed Web-server systems.

Server System

In the Industrial 4.0 era, almost all activities and transactions are carried out via the internet, which basically uses web technology. For this reason, it is absolutely necessary to have a high-performance web server infrastructure capable of serving all the activities and transactions required by users without any constraints. This research aims to design a high-performance (high availability) web server infrastructure with low cost (low cost) and energy efficiency. low power) using Cluster Computing technology on the Raspberry Pi Single Board Computing and Docker Container technology. The cluster system is built using five raspberry Pi type 4B modules as cluster nodes, and the Web server system is built using docker container virtualization technology. Meanwhile, cluster management uses Docker Swarm technology. Performance testing (Quality of Service) of the cluster system is done by simulating a number of loads (requests) and measuring the response of the system based on the parameters of Throughput and Delay (latency). The test results show that the Raspberry Pi Cluster system using Docker Swarm can be used to build a High Availability Server system that is able to handle very high requests that reach Throughput = 161,812,298 requests / sec with an Error rate = 0%.

The Web

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.

Counting Algorithm

ABSTRAKPT.Trimitra Data Teknologi adalah perusahaan yang yang bergerak dalam bidang teknologi dan informasi, website menjadi salah satu cara jembatan komunikasi antara client dan perusahaan. Banyaknya client yang mengakses membuat beban sebuah web server dalam perusahaan menjadi berat dan menimbulkan masalah yaitu down nya server yang membuat client sulit untuk mengakses website perusahaan. Untuk membantu mengatasi masalah yang terjadi diterapkannya metode load balancing dengan algoritma request counting algorithm dimana bertujuan untuk membagi beban secara merata dalam web server dan memperkecil waktu respon antara client dan server, beban terbagi dengan anggota server yang terdaftar dalam server load balancing. Dengan penerapan metode load balancing maka kerja server akan menjadi lebih maksimal karena adanya sistem high availability dimana saat salah satu server mati maka kerja server akan diambil alih oleh server yang lain. Selain metode load balance penerapan sistem dengan server mirror yang dilakukan dapat membantu memaksimalkan metode load balance karena adanya replikasi otomatis antara web server yang menjadi anggota load balance baik konten website ataupun database. Hasil yang terjadi adalah web server perusahaan akan menjadi sistem yang mampu bekerja secara baik saat melayani client dalam hal layanan web server karena beban terbagi dengan baik dan kecilnya waktu respon sehingga tidak adanya kesulitan client untuk mengakses website perusahaan.Kata kunci : Load Balance, Web Server, Mirror Server.
