A company’s application is running on Amazon EC2 instances.The company is planning a partial migration to a serverless architecture in the next year and wants to pay for resources up front.
Which AWS purchasing option will optimize the company’s costs?
Convertible Reserved Instances
Spot Instances
EC2 Instance Savings Plans
Compute Savings Plan
Explanations:
Convertible Reserved Instances offer flexibility to change instance types within a family but are limited to EC2 instances, not optimal for planned serverless migration.
Spot Instances are cost-effective for non-critical workloads, but they are not suitable for a migration with upfront payment and potential serverless use.
EC2 Instance Savings Plans provide cost savings for EC2 only and lack flexibility for serverless options.
Compute Savings Plan optimizes costs across EC2, Fargate, and Lambda, providing flexibility for the partial serverless migration and offering upfront payment options.
