serverless [create] [deploy] [invoke] [logs] [remove] [options]

serverless (sls) is a framework for building serverless applications. It deploys functions to AWS Lambda, Azure Functions, Google Cloud Functions, and others.Service configuration in serverless.yml defines functions, events, and resources. Events trigger functions from HTTP, queues, schedules, and other sources.Deployment packages code and provisions infrastructure. CloudFormation (AWS) or equivalent handles resource creation.Local invocation tests functions without deployment. This speeds up development iteration.Logs stream function output from cloud providers. They show invocations, errors, and execution details.Plugins extend functionality: custom domains, monitoring, optimization, and framework integrations.
