Question

Which AWS computing service would a developer choose if they wanted to run a serverless application?

A. AWS Elastic Beanstalk
B. Amazon Elastic Container Service (Amazon ECS)
C. AWS Lambda
D. Amazon Elastic Compute Cloud (Amazon EC2)

Answer

C. AWS Lambda

Explanation

Lambda is a serverless compute service that helps users run code without provisioning or managing servers.

AWS Lambda is the ideal computing service for running serverless applications on AWS. With Lambda, developers can run code without provisioning or managing servers. They simply upload their code and Lambda takes care of everything required to run and scale the code with high availability.

Key benefits of using AWS Lambda for serverless applications:

  1. No server management: Developers don’t need to worry about server provisioning, patching, or scaling. Lambda handles all the underlying infrastructure.
  2. Automatic scaling: Lambda automatically scales applications by running code in response to triggers or events. It can scale to handle millions of requests per second.
  3. Pay only for what you use: With Lambda’s event-driven execution model, you only pay for the compute time your code actually consumes, metered in millisecond increments. There are no charges when your code is not running.
  4. Integrated with other AWS services: Lambda seamlessly integrates with other AWS services like API Gateway, S3, and DynamoDB, making it easy to build serverless applications.

In contrast, the other options (Elastic Beanstalk, ECS, EC2) all involve some degree of server management and are not truly serverless:

  • Elastic Beanstalk simplifies app deployment but still requires managing the underlying EC2 instances.
  • ECS is a container orchestration service that requires provisioning and managing clusters of EC2 instances.
  • EC2 provides resizable compute capacity in the cloud but requires the most server management.

So for a truly serverless approach, AWS Lambda is the clear choice. It abstracts away all infrastructure management, enabling developers to focus solely on their application code.
