- Unified Web Management: Consolidate SharedAirDFW, MINTS dashboards, and related web apps on a single containerized web host.
- Improved Backups: Expand
borg.circwith 50 TB storage and automate daily snapshots + weekly off-site replication. - Enhanced Monitoring: Centralized Prometheus + Grafana stack for all VMs with alerting.
- Assess VM Consolidation: Identify which services can be containerized or merged (e.g., web + API hosting).
- Hardware Resource Allocation: Reallocate vCPUs/RAM from hypervisor to upgraded VMs.
- Develop Migration Plan: Stage-wise migration to Ubuntu, ensuring no downtime for SharedAirDFW and MINTS services.
- Implement Unified Backups: Standardize backups using Borg + off-site sync (cloud or secondary datacenter).

Questions:
- What is Mfs - mooseFS, how it works between these virtual machines
- Is there any connection to the IMD server? If so, how is it linked?
- Not all folders within mfs not accessible via IMD or MDASH
- Can we manage all mints services using one VM
