Virtualization is one of the fundamental technologies that enables cloud computing by allowing multiple virtual machines (VMs) to run on a single physical server. It abstracts hardware resources such as CPU, memory, storage, and networking into logical units that can be allocated dynamically according to user requirements. This abstraction increases resource utilization, reduces hardware costs, simplifies management, and provides the flexibility needed for modern cloud environments. Cloud service providers rely heavily on virtualization to deliver Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and even support Software as a Service (SaaS) efficiently. The importance of virtualization in cloud computing lies in its ability to maximize hardware utilization while minimizing operational expenses. Instead of dedicating one physical server to one application, virtualization enables several virtual machines to share the same physical infrastructure without interfering with each other. This consolidation reduces power consumption, cooling _____ __________ _________ _______ _______ ____ _____.
