In above Diagram we can see that clouds were contains the
data of organizations and it contains
more than one server so these are the CLUSTERS and all Clusters were connected
to each other and all Clusters are in one NETWORK so it is GRID and and overall
it is a “CLOUD COMPUTING”.
In Cloud Computing all set of servers that is CLUSTER'S are connected to each other so that it works as one SYSTEM.we can access our data anytime anywhere by using INTERNET.
Cloud computing is an extension of the object-oriented
programming concept of abstraction. Abstraction, as explained earlier, removes
the complex working details from visibility. All that is visible is an
interface, which receives inputs and provides outputs. How these outputs are
computed is completely hidden.
A cloud is similar; it applies the concept of abstraction in a physical computing environment, by hiding the true processes from a user. In a cloud computing environment, data can exist on multiple servers, details of network connections are hidden and the user is none the wiser. In fact, cloud computing is so named because a cloud is often used to depict inexact knowledge of inner workings.
