Examples of configuring virtualized systems in enterprise environments

V diplomski nalogi smo predstavili virtualizacijo v računalniških omrežjih. Najprej smo predstavili glavne vrste virtualizacije, ki se uporabljajo v računalniških omrežjih in opisali nekaj njihovih glavnih prednosti. Vpeljavo virtualizacije v računalniška omrežja smo podkrepili s primeri iz prakse. V primerih smo analizirali stanje pred virtualizacijo, postopek virtualizacije posameznih komponent omrežja in stanje po virtualizaciji, kjer smo predvsem opazovali pridobitve, ki jih je virtualizacija prinesla. Z diplomsko nalogo smo prikazali metode, ki se uporabljajo pri migraciji fizičnih komponent omrežja na virtualne, kot tudi metode za nove implementacije virtualnih instanc v omrežju. Prikazane so tudi prednosti virtualizacije v primerjavi z računalniškimi omrežji, kjer se virtualizacija ne uporablja.In this thesis we presented virtualization in computer networks. Firstly, we exhibited the main types of virtualization used in computer networks and described some of their main advantages. The incorporation of virtualization in computer networks was supported by practical examples. In each case we analyzed the state before virtualization, the process of virtualization of individual network components and the state after virtualization, where we mainly observed the gains that virtualization has brought. With the thesis we portrayed the methods used in the physical-to-virtual migration of network components, as well as methods for new implementations of virtual instances in the network. We have also displayed the advantages of virtualization, compared to computer networks where virtualization is not used
