Habitat vs Stacker 1

Easily Create/Update/Destroy many stacks in parallel (though with an understanding of cross-stack dependencies);Makes it easy to manage large environments in a single config, while still allowing you to break each part of the environment up into its own completely separate stack.;Manages dependencies between stacks, only launching one after all the stacks it depends on are finished.;Only updates stacks that have changed and that have not been explicitly locked or disabled.;Easily pass Outputs from one stack in as Variables on another (which also automatically provides an implicit dependency);Use Environments to manage slightly different configuration in different environments.;Use Lookups to allow dynamic fetching or altering of data used in Variables.;A diff command for diffing your config against what is running in a live CloudFormation environment.;A small library of pre-shared Blueprints can be found at the stacker_blueprints repo, making things like setting up a VPC easy.
