Refreshed hugo
Jul 21, 2026Completed a comprehensive platform infrastructure modernization and re-deployed the platform-hugo.service application layer.
Infrastructure Updates
- OS Layer: Migrated base host environment to Ubuntu 24.04 LTS (Noble) running the Linux 6.17 AWS kernel.
- Container Architecture: Upgraded underlying container layers to Docker Engine 29.x and containerd 2.2.x.
Deployment & Rehydration
The platform execution has shifted entirely to an Immutable Infrastructure model to eliminate configuration drift:
- Rebuilt system images from source using HashiCorp Packer.
- Provisioned fresh EC2 instances via HashiCorp Terraform using the newly baked AMIs.
- Automated final configuration rehydration utilizing AWS Systems Manager.
- Pulled the latest application image and successfully restarted
platform-hugo.service.

Ubuntu Fleet Upgraded to 24.04
Jul 20, 2026Successfully planned and executed a fleet-wide production operating system upgrade from Ubuntu 20.04 to Ubuntu 24.04 LTS. The rollout encompassed approximately 36 cloud instances alongside physical edge devices.
Execution Highlights
- Multi-Hop Pathing: Validated a repeatable multi-hop upgrade path across highly mixed instance types, explicitly targeting legacy physical hardware running non-standard boot configurations.
- Health Validation: Implemented an end-to-end pre-flight and post-upgrade validation checklist verifying OS stability, container runtime health, storage persistence, and application-layer availability.
- Zero-Downtime Orchestration: Coordinated sequenced execution over dozens of active production hosts using consistent, auditable rollback procedures, resulting in zero unplanned downtime.
During the rollout, engineering isolated an upstream container runtime regression that silently lowered critical resource limits under high production loads.
