The short version

  • Only IBM Db2 has a free tier, so it costs nothing to try first.
  • Each has a real cost: IBM Db2 cloud-based Db2 is newer than mainframe version; some legacy mainframe features not yet available in cloud; PlanetScale eBS High Availability requires 3-node configuration with replication overhead
  • They diverge on capability: IBM Db2 covers AI-powered Query Optimization, PlanetScale covers Database Branching.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

IBM Db2

  • Cloud-based Db2 is newer than mainframe version; some legacy mainframe features not yet available in cloud
  • Pricing complexity with hourly billing for compute and storage can result in unpredictable costs
  • Less community support and documentation compared to open-source alternatives like PostgreSQL
  • Requires IBM expertise and tools for optimal configuration and tuning
  • Migration from mainframe Db2 to cloud Db2 requires careful planning and testing

PlanetScale

  • EBS High Availability requires 3-node configuration with replication overhead
  • EBS Non-HA single-node option lacks redundancy and automatic failover
  • Pricing varies by cloud provider and region, requiring queries for specific rates
  • ARM64 architecture only available on EBS tier, not Metal deployments
