In this blog I will cover the three calculators I relied on during my time in SRE and that I continue to use as a Cloud Engineer.

What is SRE?

Site Reliability Engineering - “SRE is what you get when you treat operations as if it’s a software problem.” - SRE Google

Unlike the traditional DevOps philosophy of development and operations being under the same team handling all application operations, the goal of Site Reliability is the practical management of operations while teams are implementing features or new developments.

I have always worked with or in Cloud/Platform teams aspiring to charge back developers for the cost of the cloud resources they consume, but I have never seen it effectively implemented. And while I do not encourage a blameful FinOps team hunting down teams for deploying a first cut application that reached high customer engagement. It is nice when others are mindful to help correctly size an application, opt for scheduling their instances and checking queries/APIs before rushing ahead.
