Is Cloud Computing somthing new?

Definition cloud computing

1. There is not one definition of cloud computing.

2. Every one can use the name.

WikipediaCloud computing is Internet ("cloud") based development and use of computer technology ("computing").It is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet.Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them

The concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent (ca. 2007–2009) technology trends which have the common theme of reliance on the Internet for satisfying the computing needs of the users. Examples of SaaS vendors include Salesforce.com and Google Apps which provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers.

The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals

Cloud Computing represents a new way to deploy computing technology to give users the ability to access, work on, share it and store information using the Internet. The cloud itself is a network of data centers - each composed of many thousands of computers working together - that perform the functions of software on a personal or business computer by providing users access to powerful applications, platforms and services delivered over the Internet.

Cloud Cloud

Everybody is using the cloud

• 1.5 miljard people connected to the cloud.

Variants of the Clouds

• Companies host applications in the cloud that many users access through Internet Connections. The service being sold or offered is a complete end-user application.

User Level“software as a service”

• Developers can design, build and test applications that run on the Cloud provieder’s infrastructure and then deliver those applications to end-users from the provider’s servers

Developer Level“platform as a service”

• System administrators optain general processing, storage, database, management and other resources and applications through the network and pay only for what gets used.

IT Level“Infrastructure as a service”

Variants of the CloudsDeployment model

• Private cloud• Community

• Public cloud• Hybrid cloud

single organization

and is operated solely for that organization

shared by several

organizations and supports

more clouds (internal,

community, or public)

CLOUD FOR CUSTOMERS

Cloud computing promissing• Cloud can provide

almost immediate access to hardware resources

• No upfront capital investments for uses

• Cloud computing can lower IT barriers to innovation and increase interoperability between disjoint technologies.

• Enterprises of all sizes can seamlessly scale their services in correlation with client demand

• Pay-per-use billing dramatically reduce upfront costs

Faster time to market

Creation of new value

Easier to scale-out

Lower upfront IT-cost

SOME EXAMPLES

Providers can market their OpSource-powered offerings

Customers can list their SaaS, SDK, and web service offerings on the Directory

Subscribers can find a variety of on-demand applications, SDKs, and web services

Subscribers sign up for services directly with the Provider. OpSource is not involved in the transaction.
