Introduction to Stacks

An Aptible Deploy Stack is the underlying virtualized infrastructure (EC2 instances, private network, etc.) your resources (Apps, Databases) are deployed on.

Stacks provide network-level isolation of resources on Aptible Deploy. For example:

• Databases deployed in a given Stack are not accessible from Apps deployed in other Stacks
• Internal Endpoints in a given Stack are not accessible from Apps deployed in other Stacks

The Stack a given resource is deployed in is determined by its Environment's Stack:

• Each Environment is linked to a single Stack.
• Multiple Environments may be linked to the same Stack.
