What is a primary disadvantage of not using server virtualization?

Not using server virtualization leads to reduced flexibility in managing resources. In a traditional physical server environment, each server is dedicated to a specific application or service, making it difficult to adjust resources based on changing needs. If one server experiences high demand while others are underutilized, the overall efficiency is compromised, as resources cannot be dynamically reallocated.

With server virtualization, multiple virtual machines can run on a single physical server, allowing for efficient resource distribution across applications. This flexibility enables organizations to respond more quickly to fluctuating workloads, improving resource utilization and reducing costs. Consequently, without virtualization, scaling up or down to meet demand becomes cumbersome, leading to inefficient resource management.
