Serverless computing - or serverless computing - is a type of cloud architecture in which the customer does not need to provision servers for the backend code to run, but access services as needed.
The purpose of this technology is to make code composition easier for a software developer, through applications divided into individual functions that can be called and scaled individually.

How does serverless computing work?Serverless is an approach to cloud computing also known as FaaS - Function as a Service, a modality very similar to the platform as a service (PaaS). This modality allows the creation and execution of applications without the need to provision and manage virtual machines, containers, operating systems and physical servers. These activities are performed by the cloud provider.
Hosting a software application on the Internet usually involves managing some type of server infrastructure. This typically means a virtual or physical server that needs to be managed, as well as the operating system and other web server hosting processes needed for the application to run.
With a serverless architecture, the developer can focus exclusively on the individual functions of the application code, while specific services take care of all the physical hardware, operating system, virtual machine (or container) and software management of the web server . An architecture where there is no charge for downtime, drastically reducing infrastructure expenses, while simplifying the operation and allowing gains of scale for the application, if necessary.
