what is cloud computing

Cloud computing has become the perfect way to deliver enterprise software — and the chosen choice for enterprises to extend their networks or introduce new technologies.

There are two examples for cloud computing. The most common example is to run tasks in the data center of a commercial company, also known as the "public cloud" model, remotely over the internet. Cloud storage offerings – such as Amazon Web Services ( AWS), Salesforce 's CRM framework, and Microsoft Azure – all reflect this common notion of cloud computing.Most companies today adopt a multicloud approach, which simply means they are using more than one public cloud service.Cloud computing's second definition explains how it works: a virtualized pool of resources, accessible on demand, ranging from raw processing capacity to application features. Once cloud services are procured by users, the vendor handles those demands using sophisticated technology rather than manual provisioning.The main benefit is agility: the ability to apply abstract computation, storage , and network resources to workloads as needed, and the abundance of pre-constructed services.

The cloud service allows customers to acquire new capabilities without investing in new software or hardware. Alternatively, they pay a monthly fee to their cloud service or only pay for the services that they need. Users can simply set up accounts and spin virtual machines or provide software innovations by filling in web forms.It is possible to add more users or computing resources on the fly — the latter in real time as workloads demand these resources thanks to a function known as autoscaling. Your hard disk is what cloud computing isn't about. If you collect data from the hard disk, or run programs, this is called local storage and computing. All you need is physically close to you, which ensures you can access your data quickly and conveniently with one device or another on the local network.
