Question

1. which amazon ec2 option is best for long - term workloads with predictable usage patterns? (select the best answer)

spot instances
on - demand instances
reserved instances

Explanation:

To determine the best Amazon EC2 option for long - term workloads with predictable usage patterns, we analyze each option:

• Spot Instances: These are suitable for workloads that can be interrupted, as they use spare EC2 capacity and are not ideal for long - term, predictable usage.
• On - Demand Instances: They are for short - term, unpredictable workloads where you pay for what you use without long - term commitments.
• Reserved Instances: They are designed for long - term workloads with predictable usage. You can reserve capacity for a term (1 or 3 years) and get significant cost savings, which matches the requirement of long - term and predictable usage.

Answer:

C. Reserved Instances
