Hypervisor technology underpins virtualization by allowing multiple virtual machines (VMs) to run on a single physical host. These virtual machine monitors provide a layer of abstraction between hardware and virtual environments, optimizing computing resources and enhancing operational efficiency. They are essential in cloud services, data centers, and server virtualization, offering both Type 1 and Type 2 variants for different use cases.

Hypervisors serve as a layer of abstraction between hardware and virtual environments, allowing for the creation and management of virtual machines
Distinct Virtual Systems
Hypervisors optimize hardware use by dividing it into separate virtual systems, enhancing the efficiency and flexibility of computing resources
Hypervisors provide a centralized platform for managing virtual machines, including resource allocation, performance monitoring, and security enforcement
By consolidating multiple servers into a single physical machine running various virtual machines, organizations can achieve significant cost savings and operational efficiencies
Hypervisors ensure that each virtual machine operates within its own isolated environment, preventing any single instance from monopolizing resources or compromising system stability
Type 1 Hypervisors (Bare-Metal)
Type 1 hypervisors are installed directly on the host's hardware, providing high performance and robust security for enterprise-grade applications
Type 2 Hypervisors (Hosted)
Type 2 hypervisors run on top of a host operating system, offering ease of use and flexibility at the cost of some performance overhead
Hypervisors emulate the underlying hardware for each virtual machine, allowing them to run as if they were on their own separate physical machines
Hypervisors dynamically manage resources, adjusting allocations based on demand to maximize efficiency and performance across the virtual environment
Hypervisors enhance the overall efficiency of computing systems by enabling higher utilization rates of physical servers, leading to cost savings in hardware investment, energy consumption, and maintenance

Definition of Hypervisor
Software layer enabling creation/management of VMs, abstracts hardware for multiple virtual environments.
01
Function of Virtual Machines (VMs)
Software emulations of physical computers, each runs own OS, operates independently on shared hardware.
02
Benefits of Virtualization Technology
Optimizes hardware use by partitioning into virtual systems, increases efficiency and flexibility of computing resources.
