DESCRIPTION
A presentation on Cloud Computing.TRANSCRIPT
Cloud Computing
• Any situation in which computing is done in a remote location rather than on your desktop or portable device.
• Cloud computing is a broad concept of using the Internet to allow people to access technology-enabled services
• Named after the cloud representation of the Internet on a network diagram.
• Cloud computing is a general term for anything that involves delivering hosted services over the Internet.
What is Cloud Computing?
How does cloud computing differ from regular hosting?
• It is sold on demand, typically by the minute or the hour; • It is elastic -- a user can have as much or as little of a service
as they want at any given time• The service is fully managed by the provider (the consumer
needs nothing but a personal computer and Internet access).
Gmail vs Microsoft Exchange Server
• Servers and storage? No Yes• Technical Team? No Yes• Upgrades? No Yes
• Applications available on demand on aSubscription basis.
Big fast machines in some else’s data centre running an application that we access using our web browser.
Someone else owns the application and we pay a subscription fee.
Utility Computing
• Server capacity is accessed across a grid as a service.• Utility computing is the packaging of computing resources,
such as computation and storage, as a metered service similar to a traditional public utility
Multi-Tenancy• Business apps are provided as a copy to their client
companies.• But with cloud computing, it’s a single app for all the client
companies.• And its flexible enough for every1 to customize it.
