## Conclusion

Having one service connection that is shared between project reduce the maintenance task. If the service need to be updated, a token renewal for instance, it will be done in one place.

The shared service connection name will slightly change in the projects:

In the original project : The service connection will have a tagged `Shared`

In the other projects : In other project the service connection name will be as follow : `OrignalName-ProjectName`

For example: if we decide to share the service connection **AZ-POC** with the project Sandbox. The service connection name in Sandbox will be **AZ-POC-Sandbox**.
