Resource Driver Overview
Brent handles Resource Manager transition and operation requests for Resources using Resource Drivers.
The following diagram shows the interactions between Brent and a resource driver 
Resource Driver is a combination of VIM and Lifecycle drivers of TNC-O version 2.1 into a single driver concept.
Unlike in v2.1.0 where a VIM Driver handles infrastructure creation/deletion while Lifecycle Driver executes resource transitions once the resource has been created; a Resource Manager handles both infrastructure and lifecycles by serving Create/Delete as lifecycle requests.
Version compability between TNC-O and drivers
| TNC-O Version | lmctl | Ansible Lifecycle Driver | SOL 003 Lifecycle Driver | Openstack VIM Driver | Kubernetes Resource Driver |
|---|---|---|---|---|---|
| 2.0.3 | 2.0.7.1 | none | none | none | none |
| 2.1.0 | 2.4.1 | 0.5.0 - 1.1.0 | 0.0.3 - 0.0.5 | 0.4.0 - 1.0.0 | none |
| 2.2.x | >= 2.5.0 | >= 2.0.0 | 0.1.0 | >= 2.0.0 | >= 0.0.3a1 |

Next Steps
Once you understand the basics of the drivers and have installed some for your own testing, you should continue to onboard the drivers in TNC-O.
