What is the difference between cloud computing and distributed computing?

difference is that cloud computing is about infrastructure while distributed system is about execution and communication between processes. ... A distributed system is where the compute is dome across multiple processes - in the same computer or across different computer systems.

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud was inspired by the symbol that's often used to represent the Internet in flowcharts and diagrams.

In general, distributed computing is any computing that involves multiple computers remote from each other that each have a role in a computation problem or information processing.

 

In business enterprises, distributed computing generally has meant putting various steps in business processes at the most efficient places in a network of computers. In the typical transaction using the3-tier model, user interface processing is done in the PC at the user's location, business processing is done in a remote computer, and database access and processing is done in another computer that provides centralized access for many business processes. Typically, this kind of distributed computing uses the client/server communications model.
