Virtualization Types of Virtualization and Types of Hupervisors

Virtualization and it's types

1. Virtualization

2. Virtualization Virtualization relies on software to simulate hardware functionality and create a virtual computer system. This enables IT organizations to run more than one virtual system – and multiple operating systems and applications – on a single server. The resulting benefits include economies of scale and greater efficiency.

3. Virtual Machine (VM) A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.”

4. Hypervisor A thin layer of software called a “hypervisor” decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed . There are two types of hypervisors, according to their place in the server virtualization structure:  Type:1 Hypervisors , also known as bare-metal or native.  Type:2 Hypervisors , also known as hosted hypervisors.

5. Types of Hypervisor Type 1 hypervisor ( bare-metal or native hypervisor ) : 1 . VMware ESXi 2. Microsoft Hyper-V 3. Xen Server 4. Oracle VM Type 2 hypervisor (Hosted Hypervisor): 1. VMware Workstation Player 2 . Microsoft Virtual PC 3 . Oracle VM VirtualBox 4 . Parallels Desktop

6. differences between type 1 and type 2 hypervisors Feature Type 1 hypervisor Type 2 hypervisor Installation Installed directly on hardware Installed on top of an operating system Performance Typically more efficient Typically less efficient Management Typically more complex to manage Typically easier to manage Security Typically more secure Typically less secure Use cases Data centers, high-performance computing Desktops, laptops, development environments

7. Key Properties of Virtual Machines Partitioning Run multiple operating systems on one physical machine. Divide system resources between virtual machines. Isolation Provide fault and security isolation at the hardware level. Preserve performance with advanced resource controls.

8. Key Properties of Virtual Machines Encapsulation Save the entire state of a virtual machine to files. Move and copy virtual machines as easily as moving and copying files. Hardware Independence Provision or migrate any virtual machine to any physical server .

10. Server virtualization This is the most common type of virtualization, and it allows multiple VMs to run on a single physical server. Each VM has its own operating system and applications, and it can be managed independently of the other VMs on the server.

11. Desktop virtualization This type of virtualization allows users to access their desktops from any device, regardless of where they are located. The desktops are stored and managed on a central server, and users can access them using a thin client device or a web browser.

12. Storage virtualization This type of virtualization abstracts the physical storage resources of a server, making them appear as a single pool of storage. This allows for more efficient use of storage resources, and it makes it easier to manage and provision storage.

13. Network virtualization Network Virtualization is a process of logically grouping physical networks and making them operate as single or multiple independent networks called Virtual Networks.

14. Benefits of Virtualization Improved resource utilization: Virtualization allows for more efficient use of physical resources, such as CPU, memory, and storage. This can lead to cost savings, as fewer physical servers are needed to support the same workload . Increased scalability: Virtualization makes it easier to scale IT infrastructure up or down as needed. This is because new VMs can be provisioned quickly and easily, without having to purchase additional hardware.

15. Benefits of Virtualization Improved management: Virtualization simplifies the management of IT infrastructure. This is because VMs can be managed independently of the physical hardware they are running on. Enhanced security: Virtualization can help to improve security by isolating VMs from each other. This can help to prevent the spread of malware and viruses.

16. Current State of Virtualization Virtualization is a mature technology that is widely used in data centers around the world. According to a recent report by Gartner, the worldwide virtualization software market is expected to reach $7.6 billion in 2023 . There are a number of trends that are driving the growth of virtualization, including : The increasing adoption of cloud computing The need for more efficient use of IT resources The growing complexity of IT infrastructure
