Virtualization Basics

Virtualization is a technology that allows you to create virtual instances of physical resources. In the context of cloud computing, it enables multiple virtual machines (VMs) to run on a single physical server, optimizing resource usage and providing scalability.

Virtualization is the process of creating a software-based representation (or virtual version) of a physical resource, such as a server, storage device, or network resources. This allows multiple operating systems and applications to run on a single physical machine.

• Server Virtualization
• Desktop Virtualization
• Network Virtualization
• Storage Virtualization
• Application Virtualization

• Improved resource utilization
• Cost savings on hardware
• Increased scalability and flexibility
• Reduced energy consumption
• Enhanced disaster recovery solutions

The process of virtualization typically involves the following steps:

1. Select a virtualization platform (e.g., VMware, Hyper-V, KVM).
2. Install the virtualization software on the physical server.
3. Create a virtual machine instance.
4. Allocate resources (CPU, memory, storage) to the VM.
5. Install the operating system on the VM.
6. Configure network settings and install necessary applications.
            

• Regularly update and patch your virtualization software.
• Monitor resource usage to avoid bottlenecks.
• Implement strong security measures for VMs.
• Backup your VMs regularly.
• Document your virtual infrastructure for easier management.
