Four lessons in cloud sourcing and consumption

(Credit goes to Joe Daly for finding this) As follows:

  • Sourcing and managing consumption of the cloud is a dynamic exercise: constant review is needed to determine if the assets in use are useful
  • Cloud economics is a demand rather than supply game: because there is so much more flexibility in CSPs than in the traditional data center
  • Granular visibility and forecasting are needed to optimize consumption of the cloud: another case for tagging, and why it’s important to derive unit-cost economics
  • Cross-functional FinOps is essential to manage cloud sourcing and consumption: empowering this team to affect change is the key component

Rethinking ‘rehost, replatform, rearchitect’: Cloud migration for the real world

I’ve long been highly skeptical of the simplicity</Dr Evil Quotes> behind ‘rehost, replatform, rearchitect’, and this post from a CSP actually shores some of that up. It breaks it down into two primary yet expansive categories that are much more philosophical than prescriptive.
