How to get rich with cloud!
summary
Built a unified accounting service that aggregates usage from bare metal up through OpenStack and customer-facing services, aiming for zero data loss and integration into downstream billing/SAP. Ingests change events via RabbitMQ plus periodic pulls to avoid missed records, normalizes Gridscale/OpenStack heterogenous APIs with adapter logic, and stores aggregated metrics in Postgres with time-series extensions. Uses Metal³ & OpenStack Ironic for bare‑metal provisioning and a mock OpenStack API for load and chaos testing. Prototype runs in production scope but long‑term API and scale tuning continue.
