How Does Serverless Computing Work?

In a serverless architecture, developers are relieved of the burden of managing infrastructure and can solely focus on writing and deploying their code. The cloud provider handles all the backend operations, including resource provisioning and execution. When a user interacts with the application, the cloud provider dynamically allocates the required resources, executes the code, and bills the user based on resource consumption. This approach is particularly advantageous for applications experiencing unpredictable or fluctuating traffic patterns, as developers only pay for the resources they use rather than maintaining idle servers.

Serverless computing is commonly integrated with Function-as-a-Service (FaaS) platforms like AWS Lambda, Azure Functions, or Google Cloud Functions. These platforms enable developers to create modular functions, which are small, self-contained units of code designed to perform specific tasks. Various events, such as user actions like file uploads or database updates, can trigger these functions. Furthermore, developers have the flexibility to write these functions in multiple programming languages, catering to their preferences and project requirements.
