Which deployment method is recommended for production to guarantee immutable, consistent releases?

  1. A FTP upload
  2. B Run-from-package deployment (WEBSITE_RUN_FROM_PACKAGE) (correct answer)
  3. C Editing code in the portal
  4. D Manual file copy

Shortcut: Run-from-package mounts a versioned zip as a read-only file system, giving atomic swaps, faster cold starts, and no partially deployed states.
