Question 21Differentiate between cloud computing and grid computing?

Question

Accepted Answer

Cloud ComputingGrid ComputingCloud computing is used for virtualization of servers, where one server computes several tasks or services concurrently.Grid computing allocates multiple servers onto a single application.It supports long-running services (Service Oriented).It is typically used for job execution, where a program runs for a limited time (Application-Oriented).Cloud computing is used for multiple services.Grid computing is used for a single application.Its computation service is on-demand.Its computation service provides maximum computing power for one application.It involves virtualization of hardware, software, and storage platforms.It involves virtualization of data and computing resources.Examples : GoogleDrive, OneDrive, Mobile Office Applications (e.g., Office 365, Google Docs), SharePoint, Microsoft Azure, iCloud, AWS etc.Examples : GridGain, JPPF, JBossCache, EhCache etc.
