Change sets are crucial for risk management when making changes to AWS resources.
| Action | Description |
|---|---|
| Create | Submit changes for stack updates |
| View | Review anticipated changes without resource alteration |
| Execute | Apply changes to the stack, modifying resources |
| Delete | Remove unnecessary change sets |
| Rollback | Revert to the previous state if an update fails |
