Detailed explanation-1: -Cloud computing refers to applications and services that run on a distributed network using virtualized resources and accessed by common Internet protocols and networking standards.

Detailed explanation-2: -Infrastructure as a service (IaaS) is a cloud computing model that provides access to computer hardware in a cloud-based environment. The main appeal of any cloud computing service is the virtualized hardware and software.

Detailed explanation-3: -Fundamentally, cloud computing and distributed cloud computing are the same. However, distributed cloud computing extends cloud computing across geographies. Distributed cloud computing splits one task across multiple computers at different locations-all of which are networked.

Detailed explanation-4: -Grid computing is also known as distributed computing. It is a processor architecture that combines various different computing resources from multiple locations to achieve a common goal. In grid computing, the grid is connected by parallel nodes to form a computer cluster.
