  • No public tier pricing; calculator or sales call required²

Gotchas

  • medium5-10x savings are vendor claims; model your own workload with their calculator first²
  • mediumBYOC means you still pay underlying cloud compute and object-storage bills
  • mediumGuess: protocol-compatible reimplementation — verify transactions and semantics before migrating⁸
  • lowNo security page found at⁹

Best for
