AWS Serverless Microservices with Patterns and Best Practices - Identifying and Decomposing Microservices for E-Commerce

The video tutorial covers the decomposition of an ecommerce application into microservices based on business capabilities. It explains the importance of cohesive and loosely coupled services, and how to identify microservices using nouns and verbs from user stories. The tutorial also discusses different communication types between microservices, including synchronous, asynchronous, and event source mapping. Finally, it introduces AWS services like Lambda, API Gateway, EventBridge, and SQS for implementing these communication types.

What is the primary goal of using microservice architecture in a large application?

• To increase the complexity of the application

• To reduce the number of services

• To split the application into tightly coupled services

• To accelerate software development processes

Which of the following is a prerequisite for decomposing microservices?

• Services must be tightly coupled

• Services should not have an API

• Services should implement unrelated functions

• Services must be cohesive

In the context of microservices, what does a business capability represent?

• A concept from business architecture modeling

• A loosely defined function

• A random set of services

• An unrelated business process

Which nouns were identified as microservices in the ecommerce domain analysis?

• Inventory, Delivery, Payment

• User, Payment, Shipping

• Customer, Supplier, Product

• Product, Basket, Order

What role do verbs play in understanding microservices communication?

• They are irrelevant to microservices

• They help in understanding integrations

• They define the microservices

• They are used to name the services

Which AWS service is used for synchronous communication in microservices?

• Amazon SQS

• Amazon EventBridge

• AWS Lambda

• API Gateway

What is the purpose of using Amazon SQS in microservices?

• To perform CRUD operations

• To decouple microservices and process events asynchronously

• To create new microservices

• To expose Restful APIs
