Type 1 Hypervisors : These are installed directly on the physical server hardware , without needing a host operating system . They provide better performance and lower latency compared to Type 2 hypervisors . Examples include VMware ESXi , Microsoft Hyper-V , and Xen .
Type 2 Hypervisors : These run on a host operating system that provides hardware abstraction and other services . They are easier to set up and are commonly used for desktop virtualization . Examples include VMware Workstation , Oracle VirtualBox , and Parallels Desktop .

Backlinks Definition of Virtualization Definition
Virtualisation in cloud computing is a technology that allows the creation of multiple simulated environments or dedicated resources from a single, physical hardware system. It enables the abstraction and *partitioning of a physical machine* into multiple *virtual machines* (VMs), each running its own operating system and applications as if it were a separate physical device.

Definition:
Virtual clustering in cloud computing refers to the grouping of virtual machines (VMs) to work together as a single unit to provide high availability, load balancing, and resource optimization. These clusters allow for the management of multiple VMs as a cohesive entity, enhancing the efficiency, scalability, and reliability of cloud services.
Key Components and Concepts:
1. Cluster Nodes:
* Virtual Machines (VMs): The individual Security Risks Explanation: **Virtualization introduces additional layers and interfaces that can be potential attack vectors.
Impact: Vulnerabilities in Hypervisors, *virtual networks*, and **management tools can be exploited by attackers.
Mitigation: **Regularly updating and patching virtualization software, implementing strong access controls, and using security tools specifically designed for virtual environments. Virtualization Architecture and Software Definition
Virtualization architecture refers to the framework and components that enable the creation, management, and operation of virtual environments. Virtualization software includes hypervisors and management tools that facilitate the deployment and control of virtual machines (VMs) and other virtual resources.
Key Concepts
hypervisor: The **core software that enables virtualization by allowing multiple operating systems to run concurrently on a host machine.
Type 1 Hypervisor (Bare-Met Virtualization in Grid and Cloud Definition
Virtualization in grid and cloud computing refers to the use of virtualization technologies to create, manage, and optimize resources across distributed computing environments. In grid computing, virtualization enables the aggregation and efficient utilization of distributed resources. In cloud computing, it allows for the scalable and flexible provision of services over the internet.
