The article delves into virtualization, which allows for running multiple virtual machines (VMs) on a single physical hardware, effectively creating computers within computers. This technology is pivotal for numerous cloud services, although it shares the spotlight with containerization and serverless computing. The roots of cloud computing date back to the 1950s with mainframes, and as technology evolved through the 1960s with time-sharing and IBM's innovation of virtualization, the groundwork for today's cloud infrastructure was laid. Readers will also learn to set up their own VM using VirtualBox, ensuring accessibility for novice users.
Virtualization allows multiple virtual machines to run on a single physical machine, sharing resources while behaving independently, which is crucial for cloud services.
Understanding virtualization is essential, as it is the foundation of cloud computing, which has revolutionized IT by enabling the efficient use of hardware resources.
