# Cloud computing

As previously stated, cloud computing refers to the use of software or services over an internet connection, with the processing taking place in a separate location yet being supplied via the internet. The word "as-a-Service" is present in each of the cloud computing models listed earlier, and it refers to the service provided by a third party. This implies that the company won't have to deal with some of the processes involved in on-premise software installation, depending on the adopted cloud computing model.

Clients and developers may focus entirely on the application and business concepts and strategy while the backend services are taken care of by the provider of serverless computing services. Storage, networking, servers, virtualization, operating systems, middleware, runtime, and data are all managed by given backend services. As a result, the company and developers are solely accountable for the application program's logic and code. Another great benefit of serverless computing is that it is charged on a per-use basis, based on activity and computation requests. **ana -add more**
