Recommendation : 2. Anticipate the operation of services
Are the environments other than production (DEV, QA, ...) switched off or decommissioned outside the ranges of use (at night, outside the test periods) ?

Does the infrastructure / application turn off the environments which are not needed to be up all the time?
Precisions
Apart from production, which may have a 24/7 availability requirement, other environments (tests, integration, acceptance) are most often linked to human operations subject to restricted time slots, or even to limited periods. When the environments are not in use, they should be inactive in order to reduce the energy consumption of these configurations. They should be decommissioned when no further use is planned over a long period.
Use Case
Technical documentation reports expected loads and dynamic provisionning / deprovisionning rules
Link to a study which states that 30% of servers are in a "comatose" state https://www.anthesisgroup.com/wp-content/uploads/2019/11/Case-Study_DataSupports30PercentComatoseEstimate-FINAL_06032015.pdf (Amaury)
