An Example Of The Characteristics Of Cloud Computing

Introduction :

Cloud computing Defines :

Cloud Computing can be defined with many definitions as following :

 Amazon says : “Cloud Computing refers to the on-demand delivery of IT resources via the Internet with pay-as-you-go pricing”.

 Wikipedia says : “phrase used to describe a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet” But we can define Cloud computing as simple as the following

“Running any programs over the internet, instead of local computer. Storing and retreiving data over the internet, instead of local computer harddisk. Renting resources over the internet, rather than buying them on own.”

So Cloud computing is a virtual space that connects users from all over the globe. Cloud computing, in turn, refers to sharing resources, software,

On-demand self-service: A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider.

2. Broad network access: Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., smart-phones, tablets, laptops and workstations).

3. Resource pooling: The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state or datacenter). Examples of resources include storage, processing, memory and network
