The short version

  • Only Azure SQL has a free tier, so it costs nothing to try first.
  • Each has a real cost: Adyen there is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic; Azure SQL ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions
  • They diverge on capability: Adyen covers Payment processing, Azure SQL covers Intelligent Performance.

Where each one falls short

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

Adyen

  • There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
  • Published fees are indicative rather than a rate card, with real pricing negotiated
  • Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
  • Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America

Azure SQL

  • Ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions
  • Managed service reduces control over database configuration and optimization tuning
  • Pricing complexity with consumption-based model can be unpredictable at scale
  • Less operational depth compared to Amazon RDS for advanced scaling scenarios
  • Azure PostgreSQL is less compelling than dedicated PostgreSQL providers outside Azure ecosystem
