What is a key characteristic of serverless architectures?

A key characteristic of serverless architectures is that they allow developers to run applications without the need to provision, maintain, or administer servers. This model abstracts the underlying infrastructure, enabling developers to focus solely on writing code and building applications. In a serverless environment, the cloud provider automatically manages the server resources required to execute the code, scaling them up or down as needed based on the application's demands, thus enabling dynamic scaling and efficient resource use.

This approach provides several benefits, including reduced operational overhead since developers do not need to worry about server management tasks such as setup, maintenance, patching, and scaling. It can lead to faster development cycles and encourages innovation, as teams can quickly deploy features and iterate on applications without being bogged down by infrastructure concerns.
