Stacks & Lifecycle
A stack is a deployed instance of a blueprint. The Stacks page shows every piece of infrastructure your organization manages.
The Stacks Page
Navigate to Stacks in the sidebar. The page shows:
| Column | Description |
|---|---|
| Stack / App | Stack name, grouped by App Group |
| Cloud | AWS, Azure, or GCP icon |
| Env | DEV, STAGING, or PROD badge |
| Status | Healthy (green), Drifting, Failed, Degraded |
| Drift | Drift detection status |
| Cost | Monthly cost estimate |
| Created | When the stack was deployed |
| Version | Blueprint version the stack runs |
Filtering
Filter stacks by:
- Cloud: All, AWS, GCP, Azure (toggle buttons)
- Group by App: Toggle to group stacks under their App Group
App Groups in Action
Stacks deployed with an App Group (e.g., "networking") appear grouped together. This makes it easy to see all related infrastructure at a glance — your VPC, VNet, and GCP VPC all under one heading.
Stack Detail
Click any stack to see:
- Resources — every cloud resource with ARN/ID
- Configuration — current parameter values
- History — deployment timeline with diffs
- Outputs — all Pulumi/TF outputs
- Drift — current drift status
Upgrading
When a PE publishes a new blueprint version, stacks running the old version show an Upgrade button.
Platform Health shows upgrade pressure:
- "5 stacks behind" with a list of outdated stacks
- Each shows current version → latest version
- One-click upgrade per stack
Upgrade Flow
- PE publishes v1.0.2 with new governance rules
- Platform Health shows "1 stack behind: v1.0.1 → v1.0.2"
- Click Upgrade on the stack
- Archie runs a preview showing what changes
- Confirm to apply the upgrade
Destroying a Stack
To tear down infrastructure:
- Open the stack detail
- Click Destroy
- Archie runs a destroy plan showing resources to be deleted
- Confirm to destroy
- All cloud resources are removed, stack is archived
Destroyed stacks are archived, not deleted. View them via "Show archived" toggle.
