Abstract
V magistrskem delu je predstavljen visoko razpoložljiv informacijski sistem Agencije Republike Slovenije za kmetijske trge in razvoj podeželja. Z anketo uporabnikov je bila preverjena kakovost informacijskih storitev Agencije ter podrobno analizirana visoka razpoložljivost informacijskega sistema Agencije, kjer so bili podani predlogi izboljšav. Predstavljena je razpoložljivost informacijskih sistemov, ki predstavlja dostopnost želenih storitev oziroma dostopnost želenih informacij. Podrobneje sta predstavljena merjenje in izračun razpoložljivosti zaporednih, vzporednih in kompleksnih sistemov. Zajeti so koncepti visoke razpoložljivosti z osnovnimi načeli načrtovanja visoko razpoložljivih sistemov. Opredeljene so funkcije računalništva v oblaku, modeli oblačnih storitev ter oblačni modeli v uporabi. Predstavljeni so postopki integracije sistemov v oblačne strukture. V osrednjem delu je predstavljen informacijski sistem Agencije s funkcijami podpore poslovnih procesov. Izvedena je bila anketa zadovoljstva uporabnikov o uporabi spletnih storitev ter mnenje uporabnikov o podpori spletnih storitev v poslovnih procesih Agencije. Opisana sta zgodovina in razvoj informacijskega sistema s pripravami in prehodom na nove visoko razpoložljive tehnologije. Izpostavljena je primerjava sistemov različnih tehnologij na podlagi standardnih zmogljivostnih testov. Razpoložljivost storitev informacijskega sistema je bila primerjana med izračunano ter izmerjeno vrednostjo razpoložljivosti. V nadaljevanju sledi podrobna analiza informacijskega sistema z uporabo konceptov visoke razpoložljivosti. V zaključku analize so predlagane izboljšave informacijskega sistema za doseganje boljše razpoložljivosti. Predstavljeni so tudi koraki za integracijo informacijskega sistema v privatni oblak z analizo integracije.

Title:PROVIDING QUALITY INFORMATION SERVICES IN HIGH-AVAILABILITY SYSTEMS
Abstract:
The thesis presents high availability information system of the Agency of the Republic of Slovenia for Agricultural Markets and Rural Development. With a user survey the quality of information services of the Agency was checked and detailed analysis of the high availability of the information system of the Agency was checked as result analysis suggestions were given for improvements. At the beginning the availability of information system that represents the availability of desired services and the availability of the desired information is presented. More information is presented for the measurement and calculation of the availability of serial, parallel and complex systems. Basic concepts of high availability are introduced and covered by design principles. Functions of cloud computing, cloud service models, and cloud models in use are described. The procedures used for system integration in cloud structures are presented. In the central part, the information system of the Agency is described with the support functions of business processes. We performed a survey of customer satisfaction with the use of web services and user opinion on the support for web services in business processes of the Agency. History and development of the information system with preparations for the transition to the new high-availability technologies are described. A comparison of different systems of technologies based on standard performance tests is presented. The availability of the information system was compared between the calculated and measured values of the availability. In addition, a detailed analysis of the information system using the concepts of high availability is described. The results of the analysis are the proposed improvements to the information system in order to achieve better availability. The work includes the steps for the integration of information system in a private cloud with the analysis of the integration.

Keywords:quality, availability of services, principles of availability, high availability, high availability clustering, cloud structure
