Implementing a simple and effective tagging strategy for visibility and monitoring is one of the most important aspect of cloud cost control. From our experience, this is where most of our own users start.

Knowing the "why's" and "where" will help everyone within the org (eng and finance) make better decisions on what and where to focus on (https://www.cloudforecast.io/blog/aws-tagging-best-practices...). Also, it'll make AWS Cost Explorer or any other cost managements tools WAY more effective.

Cost optimization can feel like drinking from a firehouse since there are so many different strategies, and approaches to it (autoscaling, spot, reserved instances/savings plans, eliminating idle & wasted resources, etc.). Also, you have to apply your OWN organizational context to it as well (business and tech side). There is a fine balance companies and eng dept need to take with cloud cost control since it can be a huge time commitment to pull your end dept into.
