AWS Serverless Microservices with Patterns and Best Practices - Deploy and Test Serverless Product Microservices Sync Fl

This video tutorial covers the deployment and testing of a serverless microservices architecture using AWS services like API Gateway, Lambda, and DynamoDB. It begins with an introduction to the architecture, followed by a code fix to prevent potential errors. The tutorial then details the deployment process using AWS CDK, including synthesizing a CloudFormation template and verifying the deployment through the AWS Management Console. Finally, it demonstrates testing the deployed services using Postman, ensuring all components function as expected.

What components are included in the serverless product microservices architecture?

• Amazon API Gateway, AWS Lambda, and RDS

• Amazon EC2, AWS Lambda, and S3

• Amazon API Gateway, AWS Lambda, and DynamoDB

• Amazon S3, AWS Lambda, and RDS

Why is it important to fix the missing break statement in the switch block?

• To prevent syntax errors

• To enhance performance

• To avoid running multiple cases unintentionally

• To improve code readability

What is the purpose of synthesizing a CloudFormation template using AWS CDK?

• To generate a deployable infrastructure template

• To create a backup of the application

• To optimize the application code

• To test the application locally

What should be ensured before running the CDK deploy command?

• The database is populated

• Docker is installed and running

• The application is fully tested

• The code is minified

What does the CDK diff command help identify?

• Code syntax errors

• Differences between the stack and codebase

• Performance bottlenecks

• Security vulnerabilities

Why is it beneficial to use the CDK diff command before deployment?

• To increase application speed

• To identify potential security implications

• To reduce deployment time

• To minimize resource usage

What is the role of the CDK deploy command?

• To generate a CloudFormation template

• To deploy the stack to AWS CloudFormation

• To test the application

• To rollback changes

How can you monitor the deployment status of the stack?

• By using the AWS CLI

• By reviewing the application logs

• By checking the AWS Management Console

• By inspecting the source code

What should be verified in the AWS Management Console after deployment?

• The deployed resources like API Gateway and Lambda

• The local development environment

• The Docker configuration

• The application code

What is the expected response when testing the API endpoint with no data in DynamoDB?

• A success message with data

• A 404 error

• A 500 error

• An empty response
