Cloud Computing (CC) is a large collection of on-demand and scalable virtualized resources that can access through the Internet. It has become a buzzword in high-performance distributed computing as it provides on-demand service provisioning to a shared pool of resources over the Internet in a self-service, dynamically scalable, and metered manner. The primary goal of CC is to come up with scalable access to computing resources and IT services. Moreover, cloud computing can store large amounts of data across various topics.
A cloud can move large amounts of data from a local system with limited space to an unlimited data storage space. The characteristics of cloud computing are, On-demand self-service, Broad network access, Rapid Elastic Capacity, Self-service Interface, and Measured Service. The benefits of CC are: better collaboration, advanced security, data loss prevention, Scalability, and flexibility. CC is offered in three different models. These models are built to satisfy the requirements of the client, such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
