Design and Implementation of Construction System with High-Availability Application Service Environment

Abstract

Abstract:This research is to use the virtualization technology to setup a network infrastructure and use it as a basis to design a system for constructing high-availability application service. The key to design lies in standardization of IT (Information Technology), which can be divided into 3 aspects of standardization: 1) Standardization of IT Infrastructure, which is used for defining standardization of network architecture, clustering, and virtualization; 2) Standardization of Settling Steps, which uses the standardized cluster and network architecture to define standardization of user parameter, service delivery and load balance; 3) Standardization of Controlling and Monitoring, which defines standardization of monitoring items and user controlling items. Finally, the design of the system for constructing high availability is realized through the way of implementation. It will obtain a complete construction system by continuously improving according to practical operation.

Implementation and verification of high data availability on database

“…However, in order to back up the data, the data is synchronized to another ISCSI storage by means of DRBD (Distributed Replicated Block Device) [6] distributed mirror. Backup between the two DBMS systems is achieved through the connection management software Keepalived [7] for the failover function [8] [9]. Relevant information such as technologies, systems, and open source software used are as follows:…”
