This description is quite confusing and difficult to understand at first but I am going to explain cloud computing in simple layman language.
You are already using cloud computing if you access your gmail account.This is most simple example but also easier to understand.Few years ago people use Microsoft’s outlook express to manage their emails.They connect to internet ,retrieve their emails,store them locally and read them offline.Now Most of us do to it this way- We login with our email and password, inbox opens(interface), we can read,create,edit,sent emails right from the interface provided by gmail. Actually we are connected to a remote computer with help of internet and interact with a program running on remote computer through a simple interface.The user do not have to care about what hardware/software is actually running his application at remote site.Remote machines owned by another company would run everything from e-mail to word processing to complex data analysis programs. It’s called cloud computing, and it could change the entire computer industry. Let me take another example.Let’s say you’re an executive at a large corporation. Your particular responsibilities include making sure that all of your employees have the right hardware and software they need to do their jobs. So you have to purchase software or software licenses to give employees the tools they require. Whenever you have a new hire, you have to buy more software or make sure your current software license allows another user.This is going to be so much stressful and costs so much money.Now cloud computing provides a solution to it.Instead of installing a suite of software for each computer, you’d only have to load one application. That application would allow workers to log into a Web-based service which hosts all the programs the user would need for his or her job.
In a cloud computing system, there’s a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user’s side decrease. The only thing the user’s computer needs to be able to run is the cloud computing system’s interface software, which can be as simple as a Web browser, and the cloud’s network takes care of the rest.
Cloud computing has been changing how most people use the web and how they store their files.Now you can put your files on some online storage (like box,google drive) and access them from anywhere with any device provided you have an internet connection.This all uses the concept of cloud computing.
The applications of cloud computing are practically limitless.A cloud computing system could execute all the programs a normal computer could run. Potentially, everything from generic word processing software to customized computer programs designed for a specific company could work on a cloud computing system.
- Clients would be able to access their applications and data from anywhere at any time.(from any computer or handheld device connected to internet ).
- It could bring hardware costs down. Cloud computing systems would reduce the need for advanced hardware on the client side.
- The companies don’t have to buy a set of software or software licenses for every employee. Instead, the company could pay a metered fee to a cloud computing company.
Cloud computing can completely change the way companies use technology to service customers, partners, and suppliers. Some businesses, such as Google and Amazon, already have most of their IT resources in the cloud. They have found that it can eliminate many of the complex constraints from the traditional computing environment, including space, time, power, and cost.
