ATS)       Nikos / Thomas/ Enzo

Status of ATS-IT cloud POC:

Cloud CCR Control Planes have been updated to be aligned with production on MCR and PCR. (26/05/2026).

Jose checked the IP range systems for VM. IT is registered, but may need to be extended afterwards to allow a better migration coverages !

Last week, Enzo cleanup all 4x CCR nodes by first removing servers, but as they where in error, he decided to remove them from Ironic and LanDB, to get a fresh auto registration and enrollment. This wasn't possible due to some Linux infrastructure changes that have been applied. Two new PCR nodes where configured to be answering all AIMS request and as CCR is closed to PDC they were supposed to answer CCR new request, but they where not allowed to connect due to firewall rules and when Clout team requested to add them in the bypass list, the auto-registration work properly.

Next steps: 

Jose will assign 2x CCR bare metal nodes and deploy them to be used as Hypervisor, allowing Diana and Thomas to use them as KBS standard containers.

Jose will also set up the IT "probing" mechanism for CCR TN region. This is using "Raly" to test all the VM "creation/migration/deletion" workflow and send data of each steps to alert and give an overview of cloud availability.

Enzo need to check with Vincent to get the right VM service IP configuration on the next activated KBS racks!
