Where each one falls short

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

IBM Cloud

  • The USD 200 starter cloud credit is valid for 30 days only
  • The larger promotional credits are time boxed: USD 1,000 for Bare Metal Servers for VPC over 120 days, USD 2,500 for Power Virtual Server over 90 days, and USD 5,000 for Backup and Recovery over 90 days
  • The USD 5,000 Backup and Recovery promotion is valid for new clients only and requires a checkout promo code

  • Beyond the free tier the account is pay as you go, so cost tracks usage with no published cap

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
