Which EC2 instance purchasing option will meet these requirements MOST (CLF-C02)
A company has a database server that is always running. The company hosts the server on Amazon EC2 instances. The instance sizes are suitable for the workload. The workload will run for 1 year.
Which EC2 instance purchasing option will meet these requirements MOST cost-effectively?
A) Standard Reserved Instances.
B) On-Demand Instances.
C) Spot Instances.
D) Convertible Reserved Instances.
Solution
Correct answer: A) Standard Reserved Instances.
Standard Reserved Instances are ideal for predictable workloads that run steadily for a specific term, in this case, a year. They offer significant cost savings compared to On-Demand instances as they involve a commitment to a specific instance type in a specific region for a term of one or three years. Since the workload is continuous and the instance sizes are suitable, Standard Reserved Instances would likely provide the best cost-effectiveness over the long term.
