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.
