Question
A company wants to optimize long-term compute costs of AWS Lambda functions and Amazon EC2 instances. Which AWS purchasing option should the company choose to meet these requirements?
A. Dedicated Hosts
B. Compute Savings Plans
C. Reserved Instances
D. Spot Instances
Answer
B. Compute Savings Plans
Explanation
To optimize long-term compute costs of AWS Lambda functions and Amazon EC2 instances, the company should choose the following AWS purchasing option:
B. Compute Savings Plans
Explanation:
Compute Savings Plans: Compute Savings Plans are a flexible and cost-effective pricing option offered by AWS. They provide savings for both AWS Lambda functions and Amazon EC2 instances over a longer-term commitment.
- AWS Lambda: With Compute Savings Plans, the company can choose a commitment to Lambda usage in terms of dollars per hour. This allows them to receive a discount on the compute costs of Lambda functions.
- Amazon EC2: Compute Savings Plans also apply to EC2 instances. The company can purchase a Compute Savings Plan and apply it to EC2 instances, which provides a discount on the compute costs of running EC2 instances.
Let’s briefly compare the other options: A. Dedicated Hosts: Dedicated Hosts are an option where the company can have dedicated physical servers for their use. However, this option does not provide the same level of cost optimization for long-term compute costs as Compute Savings Plans. C. Reserved Instances: Reserved Instances are a purchasing option where the company can reserve EC2 instances for a specified term, typically one or three years. While Reserved Instances offer cost savings over On-Demand instances, Compute Savings Plans provide more flexibility and broader coverage for both Lambda and EC2 instances. D. Spot Instances: Spot Instances are a cost-effective option for running EC2 instances, as they allow the company to bid on unused EC2 capacity. However, Spot Instances are not suitable for long-term commitments or workloads that require consistent availability.
In summary, Compute Savings Plans offer the most comprehensive and flexible option for optimizing long-term compute costs of AWS Lambda functions and Amazon EC2 instances.
