What characterizes serverless architecture?

Serverless architecture is characterized by the ability to build and run applications without having to manage the underlying infrastructure. This means that developers can focus on writing code rather than dealing with the complexities of server management, such as provisioning, scaling, and maintenance. In a serverless model, the cloud provider automatically takes care of these tasks, allowing for automatic scaling in response to the application's needs.

This shift enables rapid development and deployment since resources are allocated dynamically based on demand. Developers can deploy individual functions or microservices, and they are billed only for the resources consumed during the execution of these functions, promoting cost efficiency.

Characteristics such as managing physical servers directly, relying on local storage and infrastructure, and limiting application scaling to individual regions do not align with the principles of serverless architecture. Instead, serverless solutions leverage cloud environments that abstract away hardware and focus on executing code in response to events, making it an agile and scalable solution suitable for modern applications.
