How cloud computing works
While cloud computing services all work a little differently, many provide a friendly, browser-based dashboard that makes it easier for IT professionals and developers to order resources and manage their accounts. Some cloud computing services are also designed to work with REST APIs and a command-line interface, giving developers multiple options.
Assume that you are an executive at a very big corporation. Your particular responsibilities include to make sure that all of your employees have the right hardware and software they need to do their jobs. To buy computers for everyone is not enough. You also have to purchase software as well as software licenses and then provide these softwares to your employees as they require. Whenever you hire a new employee, you need to buy more software or make sure your current software license allows another user. It is so stressful that you have to spend lots of money.
But, there may be an alternative for executives like you. So, instead of installing a suite of software for each computer, you just need to load one application. That application will allow the employees to log-in into a Web-based service which hosts all the programs for the user that is required for his/her job. Remote servers owned by another company and that will run everything from e-mail to word processing to complex data analysis programs. It is called cloud computing, and it could change the entire computer industry.
In a cloud computing system, there is a significant workload shift. Local computers have no longer to do all the heavy lifting when it comes to run applications. But cloud computing can handle that much heavy load easily and automatically. Hardware and software demands on the user’s side decrease. The only thing the user’s computer requires to be able to run is the cloud computing interface software of the system, which can be as simple as a Web browser and the cloud’s network takes care of the rest.
Uses of cloud computing
You are probably using cloud computing right now, even if you don’t realise it. If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games or store pictures and other files, it is likely that cloud computing is making it all possible behind the scenes. The first cloud computing services are barely a decade old, but already a variety of organisations—from tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all sorts of reasons.
Here are a few examples of what is possible today with cloud services from a cloud provider:
Create new apps and services
Quickly build, deploy and scale applications—web, mobile and API—on any platform. Access the resources you need to help meet performance, security and compliance requirements.
Test and build applications
Reduce application development cost and time by using cloud infrastructures that can easily be scaled up or down.
Store, back up and recover data
Protect your data more cost-efficiently—and at massive scale—by transferring your data over the Internet to an offsite cloud storage system that is accessible from any location and any device.
Unify your data across teams, divisions and locations in the cloud. Then use cloud services, such as machine learning and artificial intelligence, to uncover insights for more informed decisions.
Stream audio and video
Connect with your audience anywhere, anytime, on any device with high-definition video and audio with global distribution.
Use intelligent models to help engage customers and provide valuable insights from the data captured.
Deliver software on demand
Also known as software as a service (SaaS), on-demand software lets you offer the latest software versions and updates around to customers—anytime they need, anywhere they are.
