AWS Lambda and Serverless

What is AWS Lambda?

• A fully managed relational database service

• A virtual private network solution

• A service for managing containers at scale

• A serverless compute service that runs your code in response to events

What is the main advantage of using AWS Lambda for serverless computing?

• It provides direct access to virtual machines for complete control.

• It eliminates the need to manage server infrastructure, automatically scaling based on demand

• It allows you to run Docker containers on virtual instances.

• It provides built-in database management for applications.

How is AWS Lambda priced?

• Based on the number of function invocations and memory used

• A flat monthly fee per function

• Based on the execution time of the function

• There is no cost for using AWS Lambda

What does the term "event-driven" mean in the context of serverless computing?

• Running applications on a set schedule

• Triggering code execution based on external events

• Storing data in a NoSQL database

• Building serverless applications without using APIs

How does AWS Lambda handle code deployment and scaling?

• Developers need to manually deploy code to Lambda instances

• AWS Lambda automatically deploys code to multiple EC2 instances

• AWS Lambda manages the deployment and scaling automatically

• Code is deployed using AWS Elastic Beanstalk

What is the maximum execution time for a single AWS Lambda function?

• 1 minute

• 5 minutes

• 15 minutes

• 60 minutes

Which statement about AWS Lambda and serverless architecture is true?

• AWS Lambda requires you to provision and manage servers for code execution.

• In serverless architecture, you are responsible for managing the underlying infrastructure.

• AWS Lambda automatically scales your code in response to incoming traffic

• AWS Lambda only supports applications written in Java.
