AWS Lambda Overview

What types of applications can AWS Lambda support?

• Event-driven applications triggered by events such as HTTP requests, DynamoDB table updates, or state transitions.

• Static web applications that do not require server-side processing.

• Mobile applications that require constant server connections.

• Desktop applications that run on local machines without cloud integration.

What are the limits of the AWS Lambda free tier?

• Up to 1 million function invocations and 400,000 GB-seconds of compute time per month.

• Up to 500,000 function invocations and 200,000 GB-seconds of compute time per month.

• Up to 2 million function invocations and 1 million GB-seconds of compute time per month.

• Up to 1 million function invocations and 1,000,000 GB-seconds of compute time per month.

What is the role of AWS Lambda in event-driven architectures?

• AWS Lambda is used for data storage in event-driven architectures.

• AWS Lambda is central to event-driven architectures, allowing functions to be triggered by various events.

• AWS Lambda is primarily used for managing databases in event-driven architectures.

• AWS Lambda is a tool for monitoring network traffic in event-driven architectures.

What is the pricing model for AWS Lambda?

• AWS Lambda uses a subscription-based pricing model.

• AWS Lambda uses a pay-per-use pricing model, charging based on the number of requests and the duration of code execution.

• AWS Lambda charges a flat monthly fee regardless of usage.

• AWS Lambda offers a free tier with unlimited usage.

What is AWS Lambda?

• A cloud storage service for storing files and data.

• A serverless computing service that automatically runs code in response to events, without requiring management of the underlying infrastructure.

• A virtual machine service that allows users to run applications on dedicated servers.

• A database service that provides scalable and managed database solutions.

What is the difference between AWS Lambda and traditional server-based computing?

• AWS Lambda requires server management, while traditional computing is serverless.

• AWS Lambda is serverless, meaning users do not manage servers, while traditional computing requires server management.

• AWS Lambda is a type of traditional server-based computing.

• There is no difference; both are the same.

What are some programming languages supported by AWS Lambda?

• Python

• Ruby

• Swift

• PHP

What is the purpose of monitoring AWS Lambda usage?

• To improve the performance of the Lambda function

• To understand and control costs, especially as workloads scale.

• To increase the number of concurrent executions

• To manage the deployment of Lambda functions

What are the advantages of using AWS Lambda?

• Zero server management, automatic scaling, event-driven architecture, and cost efficiency.

• Requires manual server management and scaling.

• Limited to specific programming languages only.

• High upfront costs and complex setup.

What is the role of AWS Lambda in reducing operational costs?

• AWS Lambda reduces operational costs by eliminating the need for server management and charging only for usage.

• AWS Lambda increases operational costs by requiring constant server maintenance.

• AWS Lambda has no impact on operational costs as it is a paid service.

• AWS Lambda reduces operational costs by providing unlimited server capacity.
