AWS resource reference
EC2 instance
A VPC-owned compute design placed on a subnet. An image label is design text; Atlas does not resolve it into an AMI or start an instance.
In Atlas
A VPC-owned compute design placed on a subnet. An image label is design text; Atlas does not resolve it into an AMI or start an instance.
Use editor controls for selection, inspector drafts and action menus. Creating or editing this design data does not create an AWS resource.
Fields and editing
| Field / label | Meaning and behaviour | Defaults and constraints |
|---|---|---|
| VPC Parent | Atlas reference to VPC; canonical resource ID, not an AWS ID. Read-only ownership. | Required. |
| Instance Type | Editable instance-size text. | Required, max 255 characters. Interactive default t3.micro. No live AWS catalogue lookup. |
| Image ID | Editable AMI/design image identifier. | Required, max 255 characters. Interactive default Amazon Linux 2023 is a label, not a resolved region-specific AMI ID. |
| Lifecycle | Editable lifecycle enum. | OnDemand (bare default) or Spot. |
| Subnet | Atlas reference to Subnet; canonical resource ID, not an AWS ID. Editable association/placement selector. | Optional bare default null; interactive creation associates the chosen host. |
| Security Groups | Atlas reference to Security Group; canonical resource ID, not an AWS ID. Association list displayed by the panel; generic editable-reference controls are not guaranteed for every list. | Bare default empty. |
| Network Interfaces | Existing inline attachment records can expose scalar details; no generic create/remove collection controls. | Network-interface attachment fields. |
| Block Devices | Existing inline volume attachment records; no generic create/remove controls. | EBS attachment fields. |
| Instance Profile | Atlas reference to IAM instance profile; canonical resource ID, not an AWS ID. Association summary rather than an inline editing promise. | Optional bare default null. |
AWS reference
Official AWS service guide explains the service. AWS property reference is a comparison reference. Atlas is an offline design model; its fields are not a promise of direct AWS API/CloudFormation equivalence or regional availability.
