Abstract

GDAS sustav jest skalabilna poslužiteljska aplikacija za prikupljanje senzorskih podataka odnosno podataka iz senzorske mreže. Aplikacija je razdijeljena na nekoliko dijelova, od kojih je svaki izveden kao jedan ili više mikroservisa. Glavni djelovi su prikupljanje podataka iz senzorskih mreža (mikroservisi Wizard i Apprentice), obrada (Pigeon), pohrana (Worker) i dohvat pohranjenih podataka (Santa). Osim navedenih mikroservisa, za potpuno funkcioniranje sustava, koriste se programi za pohranu podataka na računalne sustave, baza podataka MongoDB, i za međusobnu komunikaciju mikroservisa, red poruka RabbitMQ. Podsustav za međusobnu komunikaciju, osim RabbitMQ programa, sastoji se i od consumer, publisher i envelope servisa koji uvode konfigurabilni komunikacijski sloj između mikroservisa i reda poruka. Podsustav za pohranu podataka naziva se fatty, a zadaća mu je maskiranje MongoDB baze podataka. Dodatni programi: Nginx, HAProxy Supervisor uvode mogućnost upravljanja opisanim skalabilnim sustavom.

Abstract (english)

GDAS system is a scalable server application for sensor data acquisition, apropos collecting data from sensor networks. Application is separated into several shares, every part of which is designed as one or more microservices. Main GDAS parts are: data acquisition from sensor networks (Wizard and Apprentice microservices), data processing (Pigeon), data storage (Worker), data provider API (Santa). Execept previously mentioned microservices, to achive full functionality, GDAS utilises mongoDB database for data storage and RabbitMQ message queue for interprocess comunication. Additionaly, communication subsystem is composed of consumer, publisher and envelope services which add configurable communication layer between microservices and message queue. Storage subsystem is called fatty and its’ task is to mask mongoDB interface. Additional programs, such as Nginx, HAProxy and Supervisor, add the means to control previously described scalable system.
