Questions and Answers

What characteristic of AWS Lambda indicates how it utilizes resources?

Lambda allows unlimited resource consumption regardless of events.
Lambda requires constant server allocation for its functions.
Lambda runs code only when it is activated by an event and uses only the compute resources that are needed. (correct)
Lambda functions are always running to ensure instant response times.

How does the approach to high availability in AWS Lambda compare to Amazon EC2?

A developer's method and configuration options for ensuring high availability with Lambda are similar to their approach with Amazon EC2. (correct)
Lambda requires no concerns about high availability for functions.
The approach is completely different with no similarities.
Developers can only ensure high availability with Lambda by using load balancers.

What is true about the environment in which AWS Lambda functions operate?

Lambda provides a static environment that does not change based on function execution.
Lambda functions run in on-demand, temporary environments, and the developer controls when new environments are created or shut down. (correct)
Developers have no control over the environment in which Lambda functions run.
Lambda functions run in permanent environments with dedicated resources.

Flashcards

Lambda's Event-Driven Execution

AWS Lambda functions execute only when triggered by a specific event, such as an API call, file upload, or database change. This ensures resources are used efficiently, only when needed.

Lambda's Pay-Per-Use Model

Lambda functions only consume compute resources when they are actively running. You pay only for the time your code is executing, making it cost-effective for short-lived or infrequent tasks.

Lambda's Runtime Environments

Lambda functions are executed within pre-configured runtime environments, providing support for popular programming languages like Python, Java, and Node.js. Developers select the runtime that best fits their code.

Lambda's Serverless Architecture

Lambda functions run within pre-configured, temporary environments, which are automatically managed by AWS. Developers do not need to manage server setup or maintenance.
