Question
A cloud administrator suggested using spot instances to reduce cloud costs for part of a new cloud infrastructure.
Which of the following conditions must be addressed by the application that will run on these instances?
- A. The application needs to store data in a database.
- B. There is a restriction for distributed network communications.
- C. The application needs to handle unpredictable instance termination. Correct
- D. Resource-intensive compute loads will be forbidden.
Explanation
Spot instances use spare provider capacity at a deep discount, but the provider can reclaim them at short notice, so the application must tolerate being interrupted and resume or redistribute its work. Spot instances place no special requirement on databases or network communication, and they can run compute-intensive workloads; in fact batch compute jobs are a common use.
