Abstract: A method receiving an indication of a creation of at least one data stack of a plurality of data stacks within a cloud computing environment; generating at least one creator-specific resource-specific tag, identifying at least: an identity of the creator and a start time when the at least one resource has been associated with the at least one data stack; associating the at least one creator-specific resource-specific tag with the at least one resource; continuously and automatically executing a lambda algorithm to determine each utilization duration metric of each resource of each data stack of the plurality of data stacks; dynamically determining the plurality of data stacks to retrieve metadata associated with the identity of the creator associated with the at least one data stack; and automatically generating a notification associated with the at least one data stack at a predetermined period of time.
