Which instance purchasing option meets these requirements MOST cost-effectively?
Dedicated hosts
Reserved Instances
On-Demand Instances
Spot Instances
Explanations:
Dedicated hosts are typically more expensive because they reserve physical servers for exclusive use, making them less cost-effective for a stable, long-term workload.
Reserved Instances offer significant discounts (up to 75%) compared to On-Demand pricing when committing to a one-year term, making them the most cost-effective option.
On-Demand Instances provide flexibility but at a higher cost compared to Reserved Instances, especially for a stable workload running continuously for a year.
Spot Instances are less reliable due to the possibility of being terminated when the market price exceeds the maximum bid, making them unsuitable for stable production workloads.
