Virtual Machines are software emulations of physical computers, encapsulating an entire computer system, from hardware to operating system, in a self-contained, isolated software environment. Coursera's Virtual Machines catalogue teaches you the concepts, design, and implementation of Virtual Machines. This includes understanding the virtualization technology, setting up and managing different types of Virtual Machines, deployment, scaling, and security. You will acquire skills for optimizing the resources and performance of Virtual Machines, managing virtual storage, and exploring the interplay of VMs in cloud computing infrastructure. Master and leverage virtual machine technology to enable flexible, scalable, and cost-effective solutions in fields such as cloud computing, data centers, and IT infrastructure management.
