Virtualization is a technology that allows multiple simulated environments or virtual instances to run on a single physical hardware system, optimizing hardware usage and providing enhanced scalability and flexibility. A hypervisor, also known as a Virtual Machine Monitor, is software that creates and manages virtual machines by abstracting the physical hardware. There are two types of hypervisors: Type 1, which runs directly on the host's hardware, and Type 2, which runs on top of an existing operating system. Key components in virtualization include CPU, memory, network, and storage, which are allocated to virtual machines to enable efficient resource management. Virtual machines offer several benefits, including consolidation, mobility, and flexibility. VMware is a leading platform for virtualization, and getting started with it involves downloading and installing VMware Workstation or Player, and creating a new virtual machine. Amazon Web Services offers a range of cloud computing services, including EC2, which provides scalability, flexibility, cost-efficiency, and reliability. Creating an AWS account is the first step in leveraging these services, and EC2 allows users to easily scale resources up or down based on demand. Understanding virtualization and cloud computing has provided valuable insights into managing and optimizing computing resources.
