There is also a third approach that is the best if you have a predictible base load with surges sometimes imo: hybrid cloud
You basically run the base load in your own data center and the surges go to the cloud. My university is evaluating this because sometimes you have multiple labs that need a lot of compute resources at the same time and local compute cluster has finite capacity.
