A company anticipates a consistent load for a new web application, with occasional spikes during seasonal events. They require a balance between cost savings and flexibility for their EC2 instances. Which purchasing option aligns with their needs while optimizing for cost?
Commit fully to Reserved Instances to gain maximum long-term discounts and manage spikes within the reserved capacity.
Rely solely on Spot Instances for the cheapest possible option, dealing with interruptions during spikes by using automatic scaling.
Opt for a combination of Reserved Instances for baseline capacity and On-Demand Instances for handling load spikes to ensure cost-effectiveness and flexibility.
Employ a Savings Plan to cover both consistent load and spikes, understanding that it may be difficult to perfectly match usage to the commitment.
