Proprietary database licensing appears straightforward upfront but hides significant long-term costs through per-core scaling penalties, vendor lock-in, paywalled observability features, and cloud DBaaS markups that can exceed 100% of underlying infrastructure costs. The piece breaks down the full TCO across licensing, operational tooling, support incentives, and strategic flexibility. Open source databases like MySQL, PostgreSQL, and MongoDB are presented as alternatives that tie costs to actual infrastructure and expertise rather than vendor permissions, with Percona positioned as a provider bridging open source freedom with enterprise-grade support, monitoring, and HA capabilities.
