AWS Serverless Microservices with Patterns and Best Practices - Creating Lambda Function for Ordering Microservices with

The video tutorial guides viewers through creating AWS Lambda functions using the AWS CDK. It covers checking documentation, using the construct library, and developing Node.js Lambda functions for microservices. The tutorial also explains configuring functions with environment variables, setting access permissions, and fixing errors. The focus is on creating an ordering microservice with read/write access to a DynamoDB table, emphasizing the use of Node.js for specific configurations.

What is the first step before starting to create a Lambda function using CDK?

• Review the CDK version 2 API references

• Set up a DynamoDB table

• Check the AWS Lambda pricing

• Install Node.js

Which existing microservices were mentioned before developing the new ordering microservice?

• Authentication and Notification

• Inventory and Shipping

• Product and Basket

• User and Payment

What is the purpose of adding an order table to the interface in the ordering function?

• To manage API requests

• To log error messages

• To store user data

• To interact with the order DynamoDB table

Why is the Node.js function preferred for creating the ordering microservice?

• It provides preconfigured options for Node.js

• It is more cost-effective

• It supports multiple programming languages

• It requires less memory

What is a crucial step when setting up the ordering function to access DynamoDB?

• Enabling multi-region replication

• Providing read/write access permissions

• Configuring a VPC

• Setting up CloudWatch alarms

What should be done after creating the ordering function to ensure it works correctly?

• Create a backup of the database

• Optimize the function for performance

• Fix bugs in the main stack

• Deploy it to a production environment

What is the benefit of using CDK for creating Lambda functions?

• It simplifies the process with infrastructure as code

• It reduces the cost of AWS services

• It automatically scales the functions

• It provides a graphical user interface
