One often-cited advantage of moving to the cloud is transparency around infrastructure spend. In our experience, this is often not the case. Teams don't always think about the decisions they make around infrastructure in terms of financial cost which is why we previously blipped about run cost as architecture fitness function. We're intrigued by the release of a new tool called Infracost which aims to make cost trade-offs visible in Terraform pull requests. It's open-source software and available for macOS, Linux, Windows and Docker and supports pricing for AWS, GCP and Microsoft Azure out of the box. It also provides a public API that can be queried for current cost data. Our teams are excited by its potential, especially when it comes to gaining better cost visibility in the IDE.
