在哥伦比亚使用SST的公司

It is a framework for building serverless apps on AWS. It includes a local development environment that allows you to make changes and test your Lambda functions live. It does this by opening a WebSocket connection to your AWS account, streaming any Lambda function invocations, running them locally, and passing back the results. This allows you to work on your functions, without mocking any AWS resources, or having to redeploy them every time, to test your changes.
