The short version

  • Each has a real cost: Amazon Connect telephony is charged separately from the platform, so the $0.038 per minute voice rate is not the whole cost of a call; PostgreSQL requires manual scaling across multiple machines for very large deployments
  • They diverge on capability: Amazon Connect covers Voice, PostgreSQL covers ACID Compliance.

Where each one falls short

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

Amazon Connect

  • Telephony is charged separately from the platform, so the $0.038 per minute voice rate is not the whole cost of a call
  • Every channel is metered individually: $0.010 per chat message, $0.080 per email and $0.014 per SMS
  • Rates vary by region and by third-party provider, so a published figure is indicative rather than final
  • Cost tracks contact volume, which makes forecasting hard for a queue with seasonal peaks

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method
