| 12 | Summary |
| 13 | ^^^^^^^ |
| 14 | |
| 15 | The "lifecycle" feature enables a PDP-D to work with the Dublin Release Policy architectural framework. |
| 16 | |
| 17 | The lifecycle feature maintains three states: TERMINATED, PASSIVE, and ACTIVE. |
| 18 | The PAP (Dublin style) interacts with the lifecycle feature to put a PDP-D in PASSIVE or ACTIVE states. |
| 19 | The PASSIVE state allows for Tosca Operational policies to be deployed. |
| 20 | Policy execution is enabled when the PDP-D transitions to the ACTIVE state. |
| 21 | |
| 22 | This feature can coexist side by side with the legacy mode of operation that predates the Dublin release. |
| 23 | |
| 24 | Usage |
| 25 | ^^^^^ |
| 26 | |
| 27 | The feature is enabled by default. |
| 28 | The lifecycle "enabled" property can be toggled with the "features" command line tool available in PDP-D containers. |
