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
MySQL
- Hot online backup is not in the free Community Server; MySQL Enterprise Backup is a paid Enterprise Edition component
- Transparent Data Encryption, data masking and de-identification are Enterprise Edition only
- MySQL Enterprise Firewall, which guards against SQL injection, and MySQL Enterprise Audit are both paid components
- External authentication against PAM or Windows Active Directory requires MySQL Enterprise Authentication
- The thread pool ships as MySQL Enterprise Scalability rather than in the community build
