High Performance Database Server (High Availability Database Server) Menggunakan MariaDB Galera Cluster

Information systems are an integral part of today's technological developments. The higher need of information systems demands the better service. One of the base foundation to improve the quality of information systems is a database server. Database server plays a role as a data storage in a network or in an information systems. A failure occurs on the database server can happen any time in a system with one server as its database. If that failure occurs, users cannot access the systems and have a risk of losing their data stored on the server. Therefore, a database server is required to work fast and has a high availability in its performance. The aim of this research is to build a high availability system where several database servers are connected so that if any failure occurs in one of them, another database server will act as a backup which is called a cluster database server. The data on each of the database server are replicated in real time so that data between nodes can be synchronized. MariaDB Galera Cluster supports multi-master database replication technique. The result of this research is a reliable system that has a high availability.
