Cloud cost comes down to two numbers: usage × rate. Engineers control usage, FinOps controls the rate, and most teams manage the two with disconnected processes. In this 45-minute session, Infracost co-founder and CEO Hassan Khajeh-Hosseini and ProsperOps FinOps specialist Dovi Wilensky show how to fix both sides. Hassan demos how Infracost shows engineers the cost of a Terraform change while they code, starting with a real customer typo that turned a $312/month instance into a $3,900/month one. Dovi then walks through how ProsperOps automates RIs, Savings Plans, and CUDs so nobody waits weeks for a bulk purchase approval.
What you’ll learn
Why engineers should own usage while rate optimization works best centralized and automated
Why nobody can price infrastructure in their head when AWS, Azure, and Google now publish over 10 million live prices
How Infracost flags cost spikes, policy violations, and invalid tag values in the editor, and gives AI coding agents your policies before they write Terraform
How to prove preventive savings to a CFO with an audit trail of cost avoided
Why ProsperOps layers in small commitments continuously instead of bulk buying every quarter, and why effective savings rate is the metric to track
What Azure’s February change to RI exchanges means for your commitment strategy
It’s built for FinOps practitioners, platform teams, and engineering leaders who want engineers and FinOps working on the same equation instead of handing problems back and forth.
