Covers the CloudStack dashboard/architecture: the management node (controls everything via API/UI, backed by a MariaDB database), Compute hosts (physical hypervisors, each running multiple KVM guest VMs that can be live-migrated between hosts, rebooted, or put into maintenance mode from the UI), and primary vs. secondary storage (primary for live VM</ins>/<ins style="font-weight: bold; text-decoration: none;">management data, secondary -- originally NFS, since migrated to Ceph for resilience -- for ISOs and templates used to build new VMs). The main project work: upgrading the CloudStack version itself, upgrading each management node's underlying OS off end-of-life CentOS onto Rocky Linux, and setting up a Galera cluster so the two management nodes replicate their database and can fail over to each other -- validated first in the Ubuntu test environment, already live in Pune, still pending client downtime approval in Noida. Also covers the general host-replacement pattern used across the client's compute fleet: migrate all VMs off a host, reformat it onto Rocky Linux, and re-add it to the cluster.</ins></div></td></tr> </table>
