⚡ Key Takeaways

  • Azure blocks simple three-part queries; Elastic Query is the workaround with Key Vault, credentials, and external tables. 𝕏
  • Live data pulls, no syncing—but expect network overhead and manual setup per table. 𝕏
  • Secure by design, but overkill for same-server DBs; plan rotations via Key Vault. 𝕏
