What is Cloud Computing? and How It Works?

Cloud computingIn a large corporation system, there is a need of computer hardware and software for all employees working in that corporation to do their jobs. Buying computers for everyone is one thing, Companies also have to purchase software and software licenses. When there is new hire, company have to buy more software and more software licenses. It is so stressful for company executive to do all this.

There is a alternative for that. Instead of installing software for each computer, you’d only have to load one application. That application would allow workers to log into Web-based service which hosts all programs user would need for their job. Remote computer owned by another company would run everything from e-mail to word pressing to complex data analysis programs. It is called Cloud Computing and it could change entire computer industry.

In the cloud computing system , there’s a less workload. Local computers no longer have to run all heavy applications. The network of computers that make up cloud handles them instead. Hardware and software demands of local user’s computers decreases. The only thing user’s computer needs to be able to run is the cloud computing system’s interface software, which is as simple as a web browser and cloud’s network takes care of the rest.

I one way or another we all have already used some form of cloud computing. If you have an e-mail account with a Wen-based e-mail service like Yahoo! Mail, Gmail or Hotmail, then you’ve had some experience with cloud computing. Instead of running a e-mail program on you computer, you log in to a Web-based e-mail account remotely. The software and storage for your account doesn’t exist on your computer, but it’s on the cloud computer.

Instead of using cloud computing for less workload and decrease in computer software and hardware need, there are some major concern about cloud computing.

Major Concerns about Cloud Computing

The major concerns about cloud computing are Security and Privacy.The idea of working with important data on another companies system worries some people. Some corporate might hesitate to work on cloud computing because they can’t keep their company’s information under lock and key.

The counterargument to this concern is that the companies offering cloud computing services stay and die by their reputations. It is beneficial for these companies to have reliable security in place. Otherwise, the service would lose all its clients. It’s important to employ the most advanced techniques to protect their clients’ data.

Privacy is the another concern about cloud computing. If a client can log in from any location to access data and applications, it’s possible that client’s privacy could be compromised. Cloud computing companies need to find the way to protect client privacy. One way to use authentication techniques such as user names and passwords, but there are hacking tricks called key logging. With key logging program hackers could records keystrokes, if they manages successfully to load a key logging program on victim’s computer.

Some questions regarding cloud computing are more elemental. does the user or company subscribing to cloud computing service own the data? Does the cloud computing system, which provides the actual storage space, own it? Is it possible for a cloud computing company to deny a clients access to another client’s data? Several companies, law firms and universities are debating these another questions about the nature of cloud computing.

How will cloud computing affect other industries? There is a growing concern in the IT industry about how cloud computing could impact the business of computer maintenance and repair. If companies switch to using streamlined computer systems, they’ll have fewer IT needs. Some industry experts believe that the need for IT jobs will migrate to the back end of the cloud computing system.
