Different Definitions Of Cloud Computing By Different Authors

Ø Common Definition-

(i) pay-per-use (no ongoing commitment, utility prices).
(ii) elastic capacity and the illusion of infinite resources .
(iii) self-service interface (iv) virtualized (abstracted) resources .

Ø  By NIST -

A pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction .






Ø  By  VANQUERO-

 Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically reconfigured to adjust to a variable load (scale), allowing also for an optimum resource utilization. 


Ø  By BUYYA-

Cloud is a parallel and distributed computing system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements (SLA) .

Ø  By  SOTOMAYOR-

 IT infrastructure deployed on an Infrastructure as a Service provider data center .

Ø  By ARMBRUST-

Data center hardware and software that provide services.

Ø  By BERKELEY-

Cloud Computing as :
(1) the illusion of infinite computing resources .
 (2) the ability to pay for use . . . as needed . . . 
 (3) the elimination of an up-front commitment by cloud users .


Ø  By  MCKINSEY-

Clouds are hardware based services offering compute, network, and storage capacity where: Hardware management is highly abstracted from the buyer, buyers incur infrastructure costs, and infrastructure capacity is highly elastic .

DATA ABSTRACTION VS DATA ENCAPSULATION

-
Image
COMPARISON BETWEEN DATA ABSTRACTION  VS DATA ENCAPSULATION Fig. Credit :  knowledge hub DATA ABSTRACTION  :- Data Abstraction is the showing of only necessary details of the object   and Hiding   the unnecessary and unwanted details . For example ,  just like how a car shows  but hides the circuitry/ implementation. Fig. Credit :  knowledge hub   DATA ENCAPSULATION  :- Wrapping of data just hiding properties and methods. The data should not go out directly  i.e. outside person is not allowed to access the data .For example , just   like how the implementations of bank account details are hidden from the banker .
