Topic 1 Question 140
2 つ選択A solutions architect needs to help a company optimize the cost of running an application on AWS. The application will use Amazon EC2 instances, AWS Fargate, and AWS Lambda for compute within the architecture. The EC2 instances will run the data ingestion layer of the application. EC2 usage will be sporadic and unpredictable. Workloads that run on EC2 instances can be interrupted at any time. The application front end will run on Fargate, and Lambda will serve the API layer. The front-end utilization and API layer utilization will be predictable over the course of the next year. Which combination of purchasing options will provide the MOST cost-effective solution for hosting this application?
Use Spot Instances for the data ingestion layer
Use On-Demand Instances for the data ingestion layer
Purchase a 1-year Compute Savings Plan for the front end and API layer.
Purchase 1-year All Upfront Reserved instances for the data ingestion layer.
Purchase a 1-year EC2 instance Savings Plan for the front end and API layer.

EC2 instance Savings Plan saves 72% while Compute Savings Plans saves 66%. But according to link, it says "Compute Savings Plans provide the most flexibility and help to reduce your costs by up to 66%. These plans automatically apply to EC2 instance usage regardless of instance family, size, AZ, region, OS or tenancy, and also apply to Fargate and Lambda usage." EC2 instance Savings Plans are not applied to Fargate or Lambda
👍 10SimonPark2022/10/29 E makes more sense than C. See https://aws.amazon.com/savingsplans/faq/, EC2 instance Savings Plan (up to 72% saving) costs less than Compute Savings Plan (up to 66% saving)
