A company has an application that runs a web service on Amazon EC2 instances and stores .jpg images in Amazon S3. The web traffic has a predictable baseline, but often demand spikes unpredictably for short periods of time. The application is loosely coupled and stateless. The .jpg images stored in Amazon S3 are accessed frequently for the first 15 to 20 days, they are seldom accessed thereafter but always need to be immediately available. The CIO has asked to find ways to reduce costs. Which of the following options will reduce costs? (Choose two.) A. Purchase Reserved instances for baseline capacity requirements and use On-Demand instances for the demand spikes. B. Configure a lifecycle policy to move the .jpg images on Amazon S3 to S3 IA after 30 days. C. Use On-Demand instances for baseline capacity requirements and use Spot Fleet instances for the demand spikes. D. Configure a lifecycle policy to move the .jpg images on Amazon S3 to Amazon Glacier after 30 days E. Create a script that checks the load on all web servers and terminates unnecessary On-Demand instances. My choice is AB

AB A: This make a lot of sense B\D: This would allow the files to be immediately accessible still vs Glacier. C: Spot instance is not guaranteed so is not suitable. E: This should be done on CloudWatch.

Yes it is AB But depending on how seldom and how immediately it requires, Glacier could be an option

At first, A,B Then the question "how to stop the on-demand instances if the spikes go unpredictably", ,plus the images need always to be immediately available. Then, the answer may be A,E

predictable baseline -> reserved (cheaper than on-demand) -> A unpredictable for short periods -> on demand -> A infrequent access after 20 days but needs immediately available -> S3 to S3 IA -> B

Reserved and Spot instances are the best combination. It's hard to say which is better, A or C. Depends on how often demand spikes happen and how many instances are needed at the time, and of course how long the company is going to run the website.

Reserved is cheaper than on-demand.. predictable baseline -> reserved for baseline. unpredictable spikes -> on-demand or spot both works. Considering the "traffic unpredictably for short periods of time" overall cost should be A cheaper than C and more durable (plus)
