The one-page guide to AWS CLI: usage, examples, links, snippets, and more. It comes with a command line interface (CLI) to help with the deployment of applications. The scope of this blog post is to give you a list of useful command lines to use for deploying your applications. We don’t want to turn you into a superhero (we’ll tackle this in a future blog post), but we want to give you the CF CLI superpower. The AWS Command Line Interface (CLI), on the other hand, is a unified tool to manage your AWS services. AWS CloudFormation provides a common language for you to describe and provision all the infrastructure resources in your cloud environment.
