AWS Serverless Microservices with Patterns and Best Practices - Deploying and Testing Serverless Product Microservices S

The video tutorial covers the setup and deployment of serverless microservices using AWS CDK. It begins with an introduction to serverless architecture, focusing on API Gateway, Lambda, and DynamoDB. The instructor guides through setting up the environment with Docker and CDK, followed by synthesizing CloudFormation templates. The tutorial then demonstrates deploying the stack, verifying resources via AWS Management Console, and testing endpoints using Postman. Best practices for infrastructure as code and object-oriented design principles are emphasized throughout.

What components are included in the serverless product microservices synchronous flow?

• API Gateway, Lambda, and DynamoDB

• Lambda, EC2, and DynamoDB

• EC2, S3, and RDS

• API Gateway, S3, and Lambda

What is the purpose of the CDK synth command?

• To deploy the stack to AWS

• To compare the current stack with the existing code

• To synthesize an AWS CloudFormation template

• To destroy the existing stack

Why is it important to run the CDK diff command?

• To deploy the stack

• To destroy the stack

• To create a new stack

• To see differences between the actual stack and the code base

What is the role of custom constructs in AWS CDK?

• They are used to deploy resources

• They encapsulate infrastructure resources for better organization

• They are used to compare stacks

• They are used to destroy resources

How can you track the deployment status of a stack?

• Using the AWS Management Console

• Using the CDK synth command

• Using the CDK diff command

• Using the AWS CLI

Which AWS service is used to manage API endpoints in this setup?

• API Gateway

• Amazon S3

• Amazon RDS

• AWS Lambda

What is verified in the AWS Management Console after deployment?

• The existence of EC2 instances

• The comparison of stacks

• The creation of API Gateway, Lambda functions, and DynamoDB

• The destruction of old resources

What tool is used to test API endpoints in this tutorial?

• AWS CLI

• Postman

• AWS Management Console

• Terraform

Which HTTP methods are tested using Postman in this tutorial?

• GET, PUT, PATCH, DELETE

• GET, POST, PATCH, DELETE

• POST, PUT, PATCH, DELETE

• GET, POST, PUT, DELETE

What is the result of a successful DELETE operation in the DynamoDB table?

• The item is unchanged

• The item is removed

• The item is duplicated

• The item is updated
