Prozorro.Sale, Ukraine's state e-auction platform for asset sales, is used by Ukraine's Ministry of Economic Development, Transparency International Ukraine, the State Deposit Guarantee Fund, and the National Bank of Ukraine. It needed uninterrupted public access even if a data center, internet link, or admin access was lost.
Triangu was mid-way through a four-stage disaster-recovery project when the war forced an accelerated shift to production: Kubernetes affinity/anti-affinity across availability zones, VPN migrated off a third-party provider via AWS export/import, and Terraform and GitLab CI/CD re-formed around one GitLab instance in a backup data center.
More than 10TB of OpenSearch/ELK logs and MongoDB data was migrated, accepting a deliberate trade-off: some non-critical logs were dropped rather than risk the migration window. Prozorro.Sale has run stably on AWS for 3+ months.
