Cloud computing is the distributed availability of computing power and computer network resources, particularly data storage and increased computing capacity, without direct user management. The term is usually used to describe cloud data centers, which are hosted by a third-party provider who offers resources such as the internet, storage, servers and software. Users typically don’t own or operate the machines that make up these data centers, and instead relying on an external service company. The services provided may include email, file storage, search engine access and application services like gaming and financial applications.
Access to digital resources
A service offered by a cloud computing provider offers users a platform to easily access their computer resources. This usually includes servers, data backup and online applications.
The provider maintains a database of computers, desktops, laptops and other peripheral devices. It then distributes computer resources to customers through a data centre. Resources are then accessed when they’re needed, rather than having to be bought from the hosting provider.
In addition to offering direct access to servers and programs, cloud computing services offer offsite analytics capabilities. These may include web, mobile and social analytics. This kind of analysis is useful for a business because it lets managers see how people are using their machines and whether certain changes are beneficial or not.
The advantages of cloud computing
The biggest advantage of cloud computing is the reduction of costs. Rather than buying costly computer hardware and software, managers can lease or purchase the necessary components from a service provider at a low cost. This also reduces IT expenses because there’s no need to buy more storage capacity or other resources that aren’t absolutely necessary for the job at hand. Managers also don’t have to worry about purchasing more licenses for management systems or application software. Again, this lowers IT costs.
Private, public and hybrid cloud providers
Different cloud computing services have different deployment models. The most popular are private cloud providers, which allow users to rent only the amount of storage space needed for their data and applications. Another model is public cloud computing, which is similar to the traditional cloud provider model, except it doesn’t restrict capacity leasing. The last model is hybrid cloud computing, which combines the best aspects of private and public cloud services. The benefits of hybrid models include lower costs and greater control.
Many businesses today are reaping the benefits of cloud services without even realizing it. They may not be aware that they’re using clouds-and the technology that goes with them-for everything from email to calendars to digital signage. Business managers can easily determine whether a new product or feature would be better suited for cloud deployment, and they can make that decision in a matter of seconds. Once they’ve made the change, they can implement it on existing public clouds or private clouds-which can lead to further savings and a reduction in IT costs all around.
