A company is launching an ecommerce application that must always be (CLF-C02)
A company is launching an ecommerce application that must always be available. The application will run on Amazon EC2 instances continuously for the next 12 months.
What is the MOST cost-effective instance purchasing option that meets these requirements?
A) Spot Instances.
B) Savings Plans.
C) Dedicated Hosts.
D) On-Demand Instances.
Solution
Correct answer: B) Savings Plans.
Amazon EC2 Savings Plans enable you to reduce your compute costs by committing to a consistent amount of compute usage for a 1-year or 3-year term. This results in savings of up to 72% over On-Demand Instance costs. Any usage up to the commitment is charged at the discounted Savings Plan rate (for example, $10 an hour). Any usage beyond the commitment is charged at regular On-Demand Instance rates. This type of plan offers a significant discount compared to the on-demand plan. It lasts from 1 to 3 years and is ideal when you know the load you need, as is the case here. On the other hand, it can't be a spot because the application needs to be available at all times.
