Serverless computing is a cloud computing model where the cloud provider automatically manages the provisioning and allocation of compute resources. This frees developers from having to manage servers and enables them to focus more on their application code.

• Serverless computing can reduce operational overhead and streamline deployment.
• It's ideal for applications with unpredictable demand or fast-scaling workloads.

Serverless computing works by abstracting away the infrastructure layer and allowing developers to focus on writing and deploying code.

• The cloud provider takes care of all the underlying infrastructure, including server maintenance, capacity planning, and automatic scaling.
• Serverless applications are event-driven, meaning they run in response to triggers or events.

A startup, StartTech, wants to build a real-time file processing application. Instead of setting up and managing servers, they use a serverless computing platform. When a file is uploaded, it triggers the serverless function to process the file. StartTech only pays for the compute time they consume, saving them time and money.
