Abstract:Diplomska naloga predstavlja prenovo informacijske tehnologije v podjetju Infrastruktura Bled d. o. o.. Podjetje je zaradi zastarele informacijske tehnologije imelo tri glavne probleme: • Prvi problem predstavlja skrb vzbujajoče dejstvo, da večino ključnih servisov podjetja poganjajo strežniki, katerim je potekla garancija in je za njih dobava nadomestnih delov v razumnem roku skoraj nemogoča. To pomeni, da bi v primeru okvare ene izmed strežniških komponent morali v najslabšem primeru zamenjati cel strežnik. V praksi lahko to pomeni večdnevni izpad določene strežniške storitve, kar seveda oteži sam delovni proces. • Drugi problem je programska oprema, kateri je v veliki večini že potekel življenjski cikel splošne podpore in kot takšna ni več upravičena do vseh segmentov podpore. Gre predvsem za operacijske sisteme na delovnih postajah in strežnikih. • Tretji problem z vidika upravljanja in nadzora predstavljajo samostojni računalniki na oddaljenih lokacijah, ki niso del domene. Z leti so se namreč potrebe po informacijski tehnologiji na oddaljenih lokacijah toliko povečale, da bi bilo te računalnike smiselno vključiti v centralni sistem. V začetnem delu naloge je zajeta analiza obstoječega stanja ter načrt prenove informacijske tehnologije. Usmeritve za prenovo informacijske tehnologije izhajajo iz standarda ISO 20000, priporočil ITIL in MOF, upoštevajo pa tudi sodobne usmerite v razvoju informacijske tehnologije, kot je računalništvo v oblaku in virtualizacija. V osrednjem delu je opisan potek prenove informacijske tehnologije. V zadnjem delu naloge je predstavljena ocena učinkovitosti izvedene prenove informacijske tehnologije. Podjetje je s prenovo informacijske tehnologije pridobilo zanesljivo, varnostno in stabilno infrastrukturo na centralni lokaciji in dislociranih lokacijah. Odkrite so bile pomanjkljivosti oz. varnostne luknje v določenih poslovnih aplikacijah. Zmanjšalo se je število fizičnih strežnikov ter najetih strežniških licenc. Precejšen napredek je podjetje doseglo pri načinu distribuiranja programske opreme, ki je sedaj za specifične aplikacije, ki niso del osnovnega paketa, centralizirano in uporabniki na zahtevo pretočijo potrebno programsko kodo. S prenovo je podjetje pridobilo dokumentacijo za posamezna področja standarda ISO 20000.

Title:REENGINEERING OF INFORMATION TECHNOLOGY IN COMPANY INFRASTRUKTURA BLED D.O.O.
Abstract:The thesis represents the reengineering of the information technology infrastructure in the company Infrastruktura Bled d.o.o. Consequently, the company faced three main problems: • The first problem implies the disturbing fact, that most of the key services are driven by servers with the expired warranty and the supply of spare parts within reasonable time would be almost impossible. This means, that in case of the endamaging one of server components the whole server should be replaced, in the worst case scenario. In practice, this can imply the multy-day outage of the specific server function, and of course, it complicates the work process. • The second problem refers to software with the support lifecycle, which has mostly expired and is not eligible for the complete support. It primarily concerns the workstation and server operating systems. • The third problem, in terms of management and supervision, concerns the independent computers in remote locations, that are not domain members (part of domain). Over the years the necessity for information technology has increased so much, that it would be meaningful to include them in the central system. The initial part of the thesis consists of the analysis of the current situation and the information technology reengineering plan. The directions for the reengineering of information technology derive from ISO 20000 standard, and ITIL and MOF Service Management Standards, considering also the new directions in information technology development, as in case with the cloud computing and virtualization. In the central part of the thesis the process of information technology reengineering has been explained. In the last part of the diploma we present the efficiency results of information technology reengineering. With this reengineering of information technology the company provided firm, safe and stabile infrastructure of central and dislocated locations. Disadvantages or security holes have been detected in the specific business applications. The number of physical servers and licences has been decreased. Speaking of the distribution of software, which is now centralized for the specific applications, excluded from the basic package, the company has made quite an achievement, and the users can download the proper programme code on-demand. With this reengineering the company has provided the documentation for different parts of ISO 20000 standard.
