Where each one falls short

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

Azure DevOps

  • First 5 users free applies to Basic plan only; Test Plans users are not included in free tier
  • Storage pricing increases per-GiB cost as volumes grow, with no volume discount threshold below $0.25

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
