Explanation:
When you have instances that will be used continuously and throughout the year, the best option is to buy reserved instances. By buying reserved instances, you are actually allocated an instance for the entire year or the duration you specify with a reduced cost.
Key Points:
- Reserved Instances provide significant cost savings (up to 75% compared to On-Demand pricing)
- Ideal for predictable, steady-state workloads with consistent utilization
- 90-100% utilization indicates these instances are running continuously
- Available in 1-year or 3-year terms with various payment options
