Selected Ans.

As the name denotes "Cloud Computing" , Softwares , services , platforms are hosted in cloud !

Cloud denotes internet , cloud computing : internet based computing

 Let me make you more clear about the same :

You are saving images , videos in your google drive or dropbox , what are those services ?

Yes , they are also examples of cloud based services.

Now a days you can find most of the softwares available in cloud .

Examples include : Microsoft office , Adobe products

Consider you need to work in a virtual machine online - within seconds you can opt in available services from vendors and start working !

There is no need of installation at your end , Isn't that cool ?

Also just imagine if you are going to setup servers , databases servers offline , How much that cost you !

There will be huge investment required if you set up datacenters for the same in limited budget with good performance.

But in cloud computing softwares , services & platforms are available for you with budget based services.

There are plans for every budget and pay as you go offers are available in most vendors.

If you dont use a particular resource in cloud ,you dont have to pay either.

Major Vendors providing Cloud resources include :

  • Microsofts Azure
  • IBM
  • Accenture
  • Dell

Since all the computation occurs in cloud , these are called "Cloud Computing"

Google says cloud computing as :

the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

What about grid computing ? 

Consider you have a large workload to complete and you are working alone , How long would that take if you compare the same task being done by a team of people towards a goal ?

Yes , the same concepts goes in grid computing , Wikipedia Says:

Grid computing is the collection of computer resources from multiple locations to reach a common goal. The grid can be thought of as a distributed system with non-interactive workloads that involve a large number of files.

Cloud computing too uses resources from multiple resources 

We can say that cloud computing is also a type of grid computing

 The grid computing architecture can solve problems with massive processing power.
