A comparative study on distributed computing and cloud computing

Distributed and Cloud computing are useful in heavy workload processing with minimum cost. Distributed computing works in a manner that a task is divided into different subtasks and distributed to various computing nodes. Cloud computing may be considered as extension of distributed computing with added features of providing on demand elastic computing resources usually on a pay per basis. There are so many situations where distributed computing and/or cloud computing can be used. This paper surveys both distributed computing and cloud computing and can be used as a roadmap for researchers, students, and commercial users.
