maybe serverless is a fad, but it can be a very useful one to reduce costs. our corp IT ops group has a google sheet that tracks staff's g suite/workspace-MDM'd corp mobile phones (is the OS updated? are the MDM policies up to date? when did the phone last check in, etc). the sheet is auto-updated every few minutes by a few lightweight cloud functions in GCP that query a few google APIs, state is stored in Datastore. the cost has never been more than $0.20 per month and it has semi-revolutionized how the corp tracked mobile devices. of course our win was multiplied by our use of g suite + associated services and APIs. but, in our case, the savings in both hard and soft costs were very real.
