Cloud Computing


                 What is Cloud computing?

Cloud computing is the use of computing resources like hardware and software which are available on the remote location and accessible over a network.
In cloud computing, the word cloud is used for "the internet" and computing  means " a type of internet-based computing".
Here  in cloud computing there is no any local servers or hardware to handle the application.
         


It should be runs through Interface software.All heavy lifting done by the web based services and the third party services holds all information like :
                             - Software       - Saved data       - Security                                                                              
                                                                       The cloud computing is used in online email services, storing online data.Cloud computing networks are large groups of servers and cloud service providers that usually take advantage of low-cost computing technology, with specialized connections to spread data-processing chores across them.  Virtualization techniques are often used to maximize the power of cloud computing.


Their are different types of cloud are their as below....


1) Public Cloud   : A public cloud can be accessed by any subscriber with an internet connection and access to the cloud space.

2) Private Cloud : A private cloud is established for a specific group or organization and limits access to just that group.

3)Community Cloud : A community cloud is stored among two or more organizations that have similar cloud requirements.

4) Hybrid Cloud : It is essentially a combination of at least two clouds, where the cloud included are mixture of public , private and community.


Some of the advantages of the cloud computing

- Unlimited, everywhere access
- Reduction in hardware and software cost.
- No physical space in office or home.
- Increase the computing process.
- Automatic redundancy.

Some of the disadvantages of the cloud computing

-  Change is hard.
-  Security & privacy
     -- User don't physically have data.
     -- Storage cloud be hacked.
-  Services Live and Die by their security reputation.
- Significally harder to infiltrate these system.
