Stacks allow you to group related workflows together into sets that can be reused across multiple projects and environments. These stacks contain several workflows that execute in sequence, with a high level of interoperability between them. They run in a chain-like order where the output of one workflow serves as the input for the next.


  • Modular Deployment: Break down large-scale deployments into manageable, smaller templates while maintaining interdependencies.
  • Automation: Chain workflows to auto-trigger subsequent processes, improving deployment efficiency.
  • Foundation: Each stack is built upon an IaC group, serving as its structural base.
  • Lifecycle Management: Stacks facilitate version updates and template additions, ensuring current and scalable infrastructure.

Stacks Workflow

Stacks operate in a sequential order:

  1. Deployment Sequence: Execute workflows in a specific order using custom actions.
  2. Default Actions: Include default Create and Destroy actions, which can be edited as needed.
  3. Chaining: Outputs from one workflow become inputs for the next, allowing seamless transitions.

Stacks vs. Workflow Groups

Stacks differ from workflow groups in that they maintain a sequence and dependencies between workflows, whereas workflow groups are a collection of independent deployments.


  • Stack: Sequential deployment of a web server, database, and load balancer with defined dependencies.
  • Workflow Group: Independent management of the same resources without structured interdependencies.
