A company plans to migrate its application to AWS and run the application on Amazon EC2 instances.The application will have continuous usage for 1 year.
Which EC2 instance purchasing option will meet these requirements MOST cost effectively?
Reserved Instances
Spot Instances
On Demand Instances
Dedicated Hosts
Explanations:
Reserved Instances offer significant cost savings for applications with continuous usage over a year, providing lower rates than On-Demand pricing.
Spot Instances can provide cost savings but are not suitable for continuous usage since they can be interrupted and may not be available when needed.
On-Demand Instances are flexible but more expensive for long-term, continuous usage compared to Reserved Instances.
Dedicated Hosts are used for compliance and licensing requirements and are typically more expensive than the other options for continuous usage.
From what I’ve seen, the answer is:
Reserved Instances
