Fear of Freedom: The Pros and Cons of Building a System on Open Source
summary
A presentation describes the open-source Ukrainian procurement platform Prozorro, detailing concrete technology choices and operational results: ~97,000 lines of code in public repos, Python/Pyramid microservices, CouchDB as the primary database, OpenStack Swift for object storage (migrated off AWS), Zabbix/Grafana/Influx monitoring, Ansible and Jenkins for automation, and ~350 virtual servers across a multi‑datacenter deployment. It gives scale metrics—230 GB DB, ~1,500 auctions and 200,000 active sessions per day, ~4 TB traffic—and notes that the platform’s monetization returns millions of UAH to the budget.
