問題文
A nightly job outgrows the single on-premises machine. The team is considering moving it to a cloud provider. Which factor most often decides whether the move helps?
選択肢
- The number of engineers who have accounts with the provider.
- Where the data already lives, because if the input has to cross the network on every run then the transfer time and egress cost can exceed the compute saving.
- Whether the cloud provider offers the same device model as the on-premises machine, since results differ between device generations, and a change of generation would force the team to validate every number again.
- The hourly price of the largest available accelerated instance type, because the job will be sized to the fastest option in order to finish in the shortest wall-clock time and the price of that option therefore determines whether the move is economically justified overall.
