WARNING! Gitlab maintenance operation scheduled for Thursday, 18 June between 19:00 and 20:00 (CET). During this time window, short service interruptions (less than 5 minutes) may occur. Thank you in advance for your understanding.
* total of 2 instances; 1 instance per MEC platform
* RNIS, WAIS are available at the _MEC_SYSTEM_ level
* total of 1 instance of each; available in all zones
* ME App use the discovered services
>_Note: The dataset available from Location service varies depending on its locality - each instance has a dataset covering its own locality only_
* ME App uses the discovered services
*See [user interface wireframes](../Sandbox-User-Interface#mec-sandbox-wireframe) for frontend details*
| Operation: | Notes: |
| --------- | ------ |
| 1. Login via the frontend & select Sandbox tab | |
| 2. Select the `dual-mec-nodes` network to deploy in the user sandbox | `dual-mec-nodes` scenario has `mep1` for Zone 1 & 2 locality and `mep2` for Zone 3 & 4 locality <br><br> Each node runs an instance of Location service with its own dataset; RNIS & WAIS are MEC system wide services.
| 2. Select the `dual-mep` network to deploy in the user sandbox | `dual-mep` scenario has `mep1` for Zone 1 & 2 locality and `mep2` for Zone 3 & 4 locality <br><br> Each node runs an instance of Location service with its own dataset; RNIS & WAIS are MEC system wide services.
| 3a. Pre-configure ME Application with Application Enablement service endpoints | Endpoints: <li>`https://try-mec.etsi.org/<my-sandbox-key>/mec_app_support/v1`<li>`https://try-mec.etsi.org/<my-sandbox-key>/mec_service_mgmt/v1`<br><br>_Note: for readability, endpoint URIs are replaced by `.../`_|
| 3b. Pre-configure ME Application with an Application Instance ID (e.g. `appInstanceId`) | MEC Platform Manager (MEPM) usually assigns `appInstanceId` to running applications <br><br> To support external user applications, the `appInstanceId` has to be generated from the frontend <br><br> Generating the `appInstanceId` asks for the locality of the ME App (e.g. `mep1` or `mep2`)|
| 4. Start ME App or environment | ME App knows nothing about available MEC services <br><br> In the following steps, ME App will learn MEC available services via Mp1 interface |
