What is a primary benefit of virtualization in data centres?

Virtualization in data centres allows multiple virtual machines to run on a single physical server, which significantly reduces the requirement for physical space. By consolidating workloads onto fewer physical servers, organizations can optimize their available space, leading to better space management and utilization within the data centre. This can facilitate more efficient use of resources and can lower overhead costs associated with maintaining larger physical infrastructures.

The reduction of physical space isn't just about fitting more servers into a given area; it also allows for improved airflow management, reduces energy consumption, and can lead to lower cooling requirements, all of which are critical in maintaining an efficient and cost-effective data centre operation. Consequently, virtualization plays a vital role in enhancing the scalability of operations while minimizing both physical and operational overhead.
