Virtualization technology simplifies an IT system in such a way that, companies, can use their servers more efficiently which are in most cases under a small load and therefore underutilized. Virtualization makes it possible to utilize the full potential of the server, reduce the number of physical servers, reduce the cost, and enable more efficient management (centralized).
Reasons to use server consolidation are primarily economically justified, but there are additional benefits:

• shorter implementation time for new solutions,
• lower maintenance costs,
• higher level of security,
• standardized server infrastructure.
