Cloud Computing is computing as a Service and not just as a Product. Under Cloud Computing, sharing of software, information and other resources takes place, to provide computing as a utility.
Cloud computing is different from traditional hosting. It's sold on demand. The service is fully managed by the provider(user just needs to have a computer and internet). User can use it in any amount at any time and user need not have knowledge about the background of the cloud to use it.
Cloud computing provides applications through internet. The applications are accessible through web browsers and mobile apps. Generally cloud computing consists of sharing of data from data-centers, which appear at a single point for the user.
Cloud computing works like, the person using it won't have to have too many software on his/her system but can download a single application which would provide him/her to log into a web-based service. Services would provide him/her various software, applications, information required for his/her job. Remote machines can access these services through e-mail to word processing to complex data analysis program.
Cloud computing decreases the load of running all the applications. The network of computer which make up the cloud handle them instead. All that user's computer  has to do is to be able to run the cloud computing's interface software, which can be a mere web browser.

Cloud Computing can be covered under the 5 layers:

  1. Cloud Client is the source providing the clouding hardware and/or software for the cloud, without which cloud would be useless.
  2. Cloud Application Service reduces the need to download the application. It reduces the work of maintenance and support of the user, by enabling the application to be run and used online.
  3. Cloud Platform Services serves as a computing platform. It helps in the use of applications, eliminating the complexities of buying and managing the layers of underlying hardware and software.
  4. Cloud Infrastructure, as the name suggests behaves like the computing infrastructure. Instead of  buying server, software, network equipment, clients; buy these resources as fully outsourced services
  5. Server contain the computing hardware and/or software programs. These are specially made to deliver the cloud services, including cloud-specific operating system and multi-core processors and combination of both. 
Cloud Computing is classified into 4 different types:

  1. Public cloud describes the cloud computing in traditional sense. Resources are provided to the general public on a self-service basis over internet via web applications by a third party who would bill these services.
  2. Community Cloud, share the infrastructure among several organisations belonging to a same community with common aims. The cloud may be controlled internally or by a third party. This can be hosted internally or externally. 
  3. Hybrid Cloud is a combination of two or more clouds(private, public or community). In this type of clouding the individual clouding type retain their identity but are still bounded together at the same time. Through this the user can get the benefits of the all the clouding computing employed in the hybrid. It can also be stated like it is a multiple cloud computing.  This allows programs and data transfer from one system to other easily. 
  4. Private Clouding is an infrastructure used solely for a single organisation. This may be operated by a third party or internally. Hosted internally or externally. But, here user may face the trouble of buying, building and managing it, unlike other clouding system. Thus, this type of clouding system is found to be less economic and easy to use and often has attracted criticism.
Cloud Computing is an attractive technology because of its various advantages. 
  • Cloud Computing reduces the cost of hardware, software, networking management and other IT expenses.
  • It provides remote access to its users from wherever they are.
  • Implementing clouding services is easy.
  • It is faster than any standard server.
  • Cloud computing provides automatic updates.

On the contrary, this technology does have a few demerits too.
  • Security can be at risk in a badly written application of clouding.
  • These days the clouding space usually goes over-utilized than its capacity causing unfulfilled functions.
  • Even under-utilization of capacity can occur. This is not good for the full performance of the infrastructure.
But Cloud computing is not the end of the technology. There are next big technologies after cloud computing for instance Peercling (PEER 2 peer CLoud computING), it does not have to be in connectivity with the back-end to work. It works like a mobile phone's application and synchronizes itself with the back-end. So it is in short removing the problem of "Out-of-Network" problem form Cloud Computing.
