Where each one falls short

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

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

DataStax

  • DataStax's own Astra DB documentation states the Enterprise plan is an annual, contract-based plan with negotiated pricing, meaning list prices are not published for that tier
  • DataStax's Astra DB documentation directs Standard plan customers to IBM's watsonx.data pricing for exact consumption-based rates following the DataStax/IBM deal, rather than publishing them on DataStax's own site
