Hardware virtualization plays a fundamental role in efficiently delivering Infrastructure-as-a-Service.

Here's why:

1. Resource Allocation: In IaaS, users are provided with virtualized hardware resources, such as servers, storage, and network. This is made possible by hardware virtualization, which allows the creation of a virtual version of the hardware to run multiple operating systems and applications simultaneously.

2. Scalability: Hardware virtualization allows IaaS providers to easily scale up or down the resources based on the demand. This is because virtual machines can be easily created, modified, or deleted as per the requirements.

3. Cost-Efficiency: With hardware virtualization, physical resources can be utilized more efficiently by dividing them into virtual machines. This reduces the need for physical hardware, thereby reducing costs.

4. Isolation and Security: Each virtual machine operates in an isolated environment. If one virtual machine crashes, it doesn’t affect the others. This isolation also improves security as one user cannot interfere with another user's resources.

5. Flexibility and Speed: With hardware virtualization, new servers can be set up or existing ones can be cloned quickly, providing great flexibility and speed in deploying new applications or handling increased workload.

So, hardware virtualization is a key enabler of the Infrastructure-as-a-Service model.
