Serverless
Definition
A cloud computing execution model in which the cloud provider runs the server, and dynamically manages the allocation of machine resources.
Deep Dive
Serverless computing is a cloud execution model where the cloud provider dynamically manages the allocation and provisioning of servers, abstracting away the underlying infrastructure management from the developer. Instead of provisioning and maintaining servers, developers deploy their application code as individual functions, which are then triggered by specific events (e.g., an HTTP request, a new file upload, a database change). The cloud provider automatically scales these functions up or down based on demand and charges only for the compute resources consumed during execution, making it a highly cost-effective model for intermittent or event-driven workloads.

- 1An AWS Lambda function triggered by an image upload to an S3 bucket to resize it
- 2A Google Cloud Function serving as a backend API for a mobile application
- 3An Azure Function used for scheduled data processing tasks without provisioning a VM.
