Topic 1 Question 84
A company wants to reduce the cost of its existing three-tier web architecture. The web, application, and database servers are running on Amazon EC2 instances for the development, test, and production environments. The EC2 instances average 30% CPU utilization during peak hours and 10% CPU utilization during non-peak hours. The production EC2 instances run 24 hours a day. The development and test EC2 instances run for at least 8 hours each day. The company plans to implement automation to stop the development and test EC2 instances when they are not in use. Which EC2 instance purchasing solution will meet the company's requirements MOST cost-effectively?
- Use Spot Instances for the production EC2 instances. Use Reserved Instances for the development and test EC2 instances.
- Use Reserved Instances for the production EC2 instances. Use On-Demand Instances for the development and test EC2 instances.
- Use Spot blocks for the production EC2 instances. Use Reserved Instances for the development and test EC2 instances.
- Use On-Demand Instances for the production EC2 instances. Use Spot blocks for the development and test EC2 instances.

  Spot blocks are not longer available, and you can't use spot instances on Prod machines 24x7, so option B should be valid.

  Well, AWS has DISCONTINUED the Spot-Block option. so that rules out the two options that use spot-block. Wait, this question must be from SAA-C02 or even 01. STALE QUESTION. I don't think this will feature in SAA-C03. Anyhow, the most cost-effective solution would be Option "b"

  The most cost-effective solution for the company's requirements would be to use Spot Instances for the development and test EC2 instances and Reserved Instances for the production EC2 instances.
  
  Spot Instances are a cost-effective choice for non-critical, flexible workloads that can be interrupted. Since the development and test EC2 instances are only needed for at least 8 hours per day and can be stopped when not in use, they would be a good fit for Spot Instances.
