The Impact of Hypervisor Layer on Database Applications

This paper presents the impact analysis of the hypervisor layer over database applications. The conclusions were reached by performing experiments with hybrid environments, composed by bare-metal servers and two types of hypervisors. The main objectives were to compare the behaviour of database applications and to determine the maximum service capacity of a virtualized database server on different environments. With the results, it was possible to assess the scalability of a database environment, according to the type of hypervisor and the number of simultaneous connections, and decide how and when to expand or reduce the virtualized infrastructure.
