Operational costs
Every IT organization needs an operations team to manage the infrastructure's regular maintenance activities. The team's responsibility is to ensure that activities such as procuring machines, maintaining SOX Compliance, executing regular updates, and security patches are done in a timely manner. The following are a few drawbacks that add up to operational costs due to VM virtualization:
- The size of the operations team is proportional to the size of the IT. Large infrastructures require larger teams, therefore more costs to maintain.
- Every enterprise is obliged to provide continuous business to its customers for which it has to employ redundant and recovery systems. Recovery systems often take the same amount of resources and configuration as original ones, which means twice the original costs.
- Enterprises also have to pay for licenses for each guest OS no matter how little the usage may be.
