Rancang Bangun Mirror Repository Linux Menggunakan Load-Balanced Mirror Service System (LMSS) Pada Private Cloud

Abstrak Meningkatnya permintaan pembaharuan aplikasi berbasis open source karena seiring meningkatnya jumlah pengguna sistem operasi Linux, oleh karenanya ketika banyak pengguna linux yang melakukan permintaan pembaharuan aplikasi menyebabkan lambatnya kecepatan unduh dan membutuhkan waktu lama. Salah satu solusinya yaitu dengan membuat mirror repository linux agar memudahkan dan menawarkan koneksi pengguna yang lebih baik. Namun demikian, suatu saat ketika semakin bertambah jumlah pengguna mirror tersebut akan mengalami penurunan kualitas download hingga dapat mengalami down, sehingga tidak dapat melayani permintaan pembaharuan pengguna dengan baik. Penelitian ini bertujuan untuk merancang dan membangun Mirror Repository Linux dengan menggunakan Load-balanced Mirror Service System (LMSS) dengan mengintegrasikan beberapa MIrror Server yang dibangun secara generate melalui Manage Large Network (MLN), dengan pembagian beban menggunakan Linux Virtual Server (LVS) pada metode Network Address Translation (NAT). Sehingga beban permintaan dari client dapat ditangani Mirror Server secara bersama – sama. Dengan demikian, rata – rata waktu download dapat berkurang sebanyak 17,2 % daripada menggunakan Single Server.AbstractThe increasing demand for open source-based application updates is due to the increasing number of users of Linux operating systems, therefore when many Linux users who request an application update cause slow download speed and takes a long time. One solution is to create Mirror Repository Linux in order to facilitate and offer better user connections. However, a time when the number of mirror users will decrease the quality of download until it can down, so it can not serve user renewal request well. This research aims to design and build linux mirror repositories by using Load-balanced Mirror Service System (LMSS) by integrating multiple Mirror Server generated via Manage Large Network (MLN), with load sharing using Linux Virtual Server (LVS) Network Address Translation (NAT). LMSS there is a Director Server as a counter / load manager that passes on the server, which will be forwarded to the destination server. So that the request load from the client can be handled Mirror Server together. Thus, the average download time can be reduced by 17.2% rather than using a single server.

Implementasi Load Balancing Web Server Menggunakan Metode LVS-NAT

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.
