A company has a set of APIs and a web application. They want to deploy it to AWS. They don’t want to manage the underlying infrastructure. Which of the following services can help to accomplish this?

Answer options:

A.AWS Lambda and API Gateway
B.AWS EC2 and Cloudfront
C.AWS Lambda and Cloudfront
D.AWS Lambda and EC2

Answer – A
The AWS Documentation mentions the following.
AWS Lambda is a compute service that lets you run code without provisioning or managing servers. AWS Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second. You pay only for the compute time you consume - there is no charge when your code is not running. With AWS Lambda, you can run code for virtually any type of application or backend service - all with zero administration.
Amazon API Gateway is an AWS service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. You can create APIs that access AWS or other web services, as well as data stored in the AWS Cloud.
Options B and D are incorrect since for EC2 you would need to manage the compute layer.
Option C is incorrect since Cloudfront is not used along with AWS Lambda.
