Cloud hosting cost optimisation
This item was not updated in last three versions of the Radar. Should it have appeared in one of the more recent editions, there is a good chance it remains pertinent. However, if the item dates back further, its relevance may have diminished and our current evaluation could vary. Regrettably, our capacity to consistently revisit items from past Radar editions is limited.

We believe that cloud hosting cost optimisation should be a continuous and integral part of our way of working, both in active projects and in platforms under maintenance, in which case it should be part of the SLA. Cloud vendors offer extensive tooling in this area which should be used for this purpose. Also consider using an architectural fitness function (Evolutionary Architectures') for optimising the run-cost. In some exceptional cases it could even be considered to change the hosting architecture / platform altogether.
