April 2025 monthly summary for 2i2c-org/infrastructure. Focused on aligning production and reflective environments, expanding CI/CD coverage for Reflective Cluster, and hardening security and cost visibility while upgrading core platform components. Delivered resource constraint propagation for jupyterhub-home-nfs across all prod hubs, expanded hub management via reflective cluster infrastructure and standardized image handling, enabled cost allocation, and completed Kubernetes upgrades with related lifecycle management.

March 2025 (2025-03): Delivered scalable infrastructure improvements for multi-site JupyterHub deployments, focusing on persistent storage, NFS migrations, monitoring, quotas, and image updates. Achieved stronger reliability, capacity planning, and observability across HHMI, 2i2c-uk, and related hubs, enabling faster incident response and business continuity.

February 2025 highlights for 2i2c-org/infrastructure: JupyterHub Home NFS improvements, expanded backup capabilities, disk provisioning, and Kubernetes upgrades across multiple hubs, with a strong focus on reliability, observability, and scalable hub provisioning. Implemented governance and quality improvements (docs, config consolidation, and lint fixes) to reduce operational toil and improve consistency across deployments.

January 2025 (2025-01) monthly summary for 2i2c-org/infrastructure Overview: Delivered core infrastructure improvements across workshop hubs, enhanced reliability and observability, and pruned legacy configurations to align with evolving architecture. Focused on business value: scalable workshop provisioning, data resilience, reduced operational overhead, and faster, safer deployments. Key outcomes by area: - Workshop hub provisioning and quotas: Added workshop hub nodes via eksctl and set up per-user homedirs volume with per-user quota limits. This enables multi-tenant usage with predictable storage and access controls, supporting scalable workshop activities without over-provisioning. - Decommissioning and configuration cleanup: Removed gridSST cluster/hub configurations and related CI/CD references, reducing maintenance burden, drift, and potential misconfigurations. Includes removal commits across gridSST staging/prod hubs and CI/CD references. - Observability and alerting: Implemented EBS volume monitoring and alerting for CryoCloud, NMFS Openscapes, and per-hub grouping (Prometheus/Alertmanager), improving reliability and faster incident response. Included documentation updates to explain per-hub alerting and PagerDuty integration. - Dynamic image building and hub tooling: Enabled dynamic image building for NMFS Openscapes staging and production hubs, accelerating iterative development and consistent hub environments. Also included enabling backups for NFS servers and related backup documentation. - Documentation and governance: Updated alertmanager/config examples and added PagerDuty/Alertmanager links; documented backups enabling for jupyterhub-home-nfs hubs; improved CI/CD job naming for clearer cluster/hub identification. Also performed Terraform backend cleanup and alignment to deployed state. Impact: These actions reduce operational overhead, shrink configuration drift, improve data resilience and observability, and accelerate safe deployments across workshop hubs. Business value realized includes better resource governance, faster onboarding for workshop users, and more reliable hub environments with clearer operational ownership. Technologies/skills demonstrated: Kubernetes (eksctl), AWS (EKS, EBS), Terraform, Prometheus/Alertmanager, PagerDuty, backups/restore, CI/CD enhancements, hub lifecycle management, decommissioning of legacy configurations, documentation.

Monthly summary for 2024-12 (infrastructure repo: 2i2c-org/infrastructure). Focused on delivering scalable, secure, and observable infrastructure for hosting JupyterHub hubs, along with CI/CD improvements and documentation to support long-term reliability and onboarding.

November 2024 monthly summary focusing on infrastructure delivery, storage modernization, and scheduling improvements across the 2i2c platform. Delivered PCHub decommissioning, EBS-backed storage migrations, hub-specific nodegroups with node selectors and node-purpose tagging, Kubernetes version upgrades, and core nodegroup cycling to improve reliability and cost efficiency. The work reduces operational risk, simplifies config, and aligns clusters with policy and best practices.

Month: 2024-10. Focused on expanding storage capacity for the AWI-CIROH project by delivering a new filestore. Key deliverable: AWI-CIROH Filestore Expansion: added filestore_b (3TB) to the filestores map, enabling additional capacity for data growth. Commit: 5662d13320a1bc9e7139c90bf785104720f156a8. No major bugs fixed this month. Overall, the work enhances storage scalability and governance, reducing risk of capacity constraints and supporting project growth. Technologies used include infrastructure as code practices, storage provisioning, and commit-based change management.
