Cloud computing refers to the delivery of computing services over the internet instead of traditional hardware and in-house data centers.
The benefits of cloud computing include on-demand availability, scalability, cost-efficiency, and global access.
Common types of cloud computing services are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
Virtualization enables the creation of virtual replicas of computer resources to optimize hardware usage, while scalability allows systems to grow or shrink computing resources based on demand.
