AWS OpsWorks Stacks helps manage applications and servers on AWS and on-premises. Every Opsworks stack includes one or more layers, each of which represents a stack component, such as a load balancer or a set of application servers.

When working with AWS OpsWorks Stacks layers, keep the following in mind:

  • Each layer in a stack must have at least one instance and can optionally have multiple instances.
  • Each instance in a stack must be a member of at least one layer, except for registered instances.
  • Instances cannot be configured directly, except for some basic settings such as the SSH key and hostname. You must create and configure an appropriate layer, and add the instance to the layer.
