A company has an uninterruptible application that runs on Amazon EC2 instances.The application constantly processes a backlog of files in an Amazon Simple Queue Service (Amazon SQS) queue.This usage is expected to continue to grow for years.
What is the MOST cost-effective EC2 instance purchasing model to meet these requirements?
Spot Instances
On-Demand Instances
Savings Plans
Dedicated Hosts
Explanations:
Spot Instances are cost-effective but not suitable for uninterruptible applications as they can be interrupted by AWS at any time.
On-Demand Instances provide flexibility but are more expensive over the long term compared to other purchasing models for continuous workloads.
Savings Plans offer a cost-effective solution for long-running, consistent workloads by providing a discount on a committed level of usage for EC2 instances.
Dedicated Hosts are typically used for regulatory or licensing requirements, making them more costly than Savings Plans for this use case.
I scheme that the answer is:
Savings Plans
I would say the answer is:
Savings Plans
