AWS Serverless Microservices with Patterns and Best Practices - Fix Custom EventBus Target Function Parameter Error

The video tutorial addresses a target function parameter issue in the Amazon event bus infrastructure. Initially, the infrastructure lacked ordering microservices, but with their completion, the error can be resolved. The tutorial guides viewers through setting up a custom event bus using AWS CDK, requiring parameters for the publisher and target function. It highlights the completion of infrastructure for ordering microservices, including Lambda, DynamoDB, and API Gateway. The video concludes with finalizing the event bus for asynchronous communication and preparing for future development of a basket checkout method using AWS SDK libraries.

What was the initial problem faced when developing the Amazon event infrastructure?

• Lack of target information for microservices

• Network connectivity issues

• Insufficient server capacity

• Incompatible software versions

What are the two parameters required for the custom event bus in AWS CDK?

• Input and Output

• Source and Destination

• Publisher and Target Function

• Publisher and Subscriber

How was the target function error resolved in the custom event bus setup?

• By upgrading the server

• By completing the ordering microservices

• By changing the programming language

• By increasing the memory allocation

What is the purpose of the basket checkout method mentioned in the final section?

• To handle user authentication

• To process payments

• To trigger events to the Amazon event page

• To manage inventory

Which AWS services are involved in the synchronous communication of ordering microservices?

• S3, EC2, and RDS

• Elastic Beanstalk, CloudWatch, and IAM

• API Gateway, Lambda, and DynamoDB

• CloudFront, SQS, and SNS
