Vizualizace dat s vysokou dostupností

Abstract

This master thesis is focused on the field of high availability data visualization, for which a visualization tool was designed. The tool was designed as a web application, HAProxy and Keepalived were chosen to ensure high availability, and the web application is deployed on the main and backup server running under Debian operation system. Capture of data failure is ensured by validation. Furthermore, an application for measuring temperature and humudity with high availability, ensured by parallel measurement by several sensors, for the Arduino platform was designed.
