Serverless computing refers to hosting applications and services without managing servers. It allows developers to build and run applications and services without thinking about servers. Common serverless offerings include AWS Lambda, Azure Functions, and Google Cloud Functions which allow running code without provisioning or managing servers. The document also discusses using serverless technologies like AWS Lambda along with other services like API Gateway, S3, and DynamoDB to build serverless applications and how webhooks can be used to trigger functions in a serverless architecture.
