Application of cloud computing technologies in the IMUNES network simulator

Tema ovog diplomskog rada je istraživanje tehnologija računarstva u oblaku i jednostavna implementacija komponenti prisutnih u većini današnjih računalnih oblaka. Najprije su opisane prednosti i nedostatci, te mogući modeli isporuke i pružanja usluga računarstva u oblaku. Nakon toga su prikazane i osnovne gradivne jedinice mrežne arhitekture računalnog oblaka. Zatim je, na operacijskom sustavu Linux, prikazana uspostava OpenStack okruženja kao jednog od mogućih rješenja za infrastrukturu nove inačice sustava IMUNES. Unutar OpenStack okruženja prikazana je implementacija nekih od najčešće korištenih komponenti u današnjim računalnim oblacima. Također je prikazana uspostava sloja za nadgledanje i promatranje pomoću alata Prometheus i Grafana uz prikupljanje metrike sa Node.js Express poslužitelja. Obzirom da sustav IMUNES koristi kontejnerizirane usluge za rad unutar operacijskog sustava Linux i za pokretanje virtualnih čvorova, prikazane su i mogućnosti upravljanja kontejneriziranim uslugama unutar OpenStack okruženja.This paper presents the research of cloud computing technologies and the simple implementation of components present in most of today's computing clouds. First, the advantages and disadvantages of cloud computing are described. Then the possible models of delivery and provision of services in the cloud are presented, as well as the basic building blocks of the computer cloud architecture. After that, the establishment of the OpenStack environment on the Linux operating system is shown, as one of the possible solutions for the infrastructure of the new version of the IMUNES system. Within the OpenStack environment, the implementation of some of the most commonly used components in today's cloud computing is presented. Also shown is the establishment of a monitoring and observation layer using Prometheus and Grafana tools along with metrics collection from the Node.js runtime environment. Given that the IMUNES system uses containerized services to work within the Linux operating system and to run virtual nodes, the possibilities of managing containerized services within the OpenStack environment are also presented
