The short version

  • Each has a real cost: ArangoDB the company has repositioned around a wider platform, so ArangoDB is now described as the foundation inside Arango rather than the product itself; Azure SQL ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions
  • They diverge on capability: ArangoDB covers Multi-model Support, Azure SQL covers Intelligent Performance.
