Comparative Analysis of High Availability Solutions

The aim of the thesis was to perform a comparative analysis of selected high availability solutions. The issue of choosing the right HA solutions is an indispensable part of any company that uses IT infrastructure. As the most commonly used solutions are the virtualization solutions of Microsoft: Hyper-V and VMWare: vSphere, they have been subjected to in-depth analysis. For this purpose, we have performed performance tests of guest systems on the above hypervisors and we tested the behavior of the cluster in the event of failure of one of the hosts.
