Practice Test 1 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
A company owns an API deployed in EC2 written using Python. All the requests can be finished within 1 second. Most of traffic happens during the daytime. The company wants to save the API cost and simplify the maintenance of the server without impacting the performance. How can this be achieved?
A. Use API Gateway with the backend services as it is.
B. Use the API Gateway along with AWS Lambda.
C. Use CloudFront along with the API backend service as it is.
D. Use ElastiCache along with the API backend service as it is.
Explanation:
Correct Answer – B
Since the company has full ownership of the API, the best solution would be to convert the code for the API and use it in a Lambda function. This can help save on cost since, in the case of Lambda, you only pay for the time the function runs and not for the infrastructure.
Then, you can use the API Gateway along with the AWS Lambda function to scale accordingly.

Note: With Lambda, you do not have to provision your own instances. Lambda performs all the administrative activities on your behalf, including capacity provisioning, monitoring fleet health, applying security patches to the underlying compute resources, deploying your code, running a web service front end, and monitoring and logging your code. AWS Lambda provides easy scaling and high availability to your code without additional effort on your part.
