Module - 8 - Network Infrastructure and Cloud Computing. Virtualization… Virtualization is the process of creating a virtual (rather than physical) version of something, such as an operating system, server, storage device, or network resource. It involves abstracting the hardware resources and presenting them in a way that allows multiple virtual instances to run concurrently on a single physical system. Virtualization is also the technology underpinning cloud computing. Here are some key concepts and benefits of virtualization… Virtual Machines (VMs) - A virtual machine is an emulation of a computer system, including the hardware components and operating system, running on a host machine. Server Virtualization - Server virtualization is one of the most common forms of virtualization. Storage Virtualization - Storage virtualization abstracts the physical storage infrastructure, such as hard drives or storage arrays, and presents it as a unified virtual storage pool. Network Virtualization - Network virtualization involves creating virtual networks that run on top of a physical network infrastructure. Securing a Virtual Machine… Securing a virtual machine (VM) is essential to protect the data and applications running within it from unauthorized access, data breaches, and other security risks. Here are some key considerations and best practices for securing a virtual machine… Secure the VM within the VM. VMs should be isolated for best security. Secure the files that hold a VM. Secure the host computer.
