Design Microservices Architecture with Patterns and Principles - AWS Lambda as a Microservice

The video tutorial discusses AWS Lambda as a core service in serverless architecture, focusing on its role in microservices. It explains microservices as independent business services that communicate over networks, offering agility and technological diversity. AWS Lambda simplifies cloud function execution, reducing operational complexity and enhancing scalability. The tutorial also addresses challenges in microservice environments, such as repeated overhead and server optimization, and how serverless resources mitigate these issues.

What is one of the main advantages of using microservices?

• They can be deployed independently.

• They eliminate the need for databases.

• They are always cheaper to run.

• They require a single technology stack.

How does AWS Lambda contribute to serverless architecture?

• By requiring manual scaling.

• By eliminating the need for code.

• By running functions in the cloud without operational complexity.

• By only supporting one programming language.

Which AWS service is commonly integrated with Lambda to invoke functions?

• Amazon S3

• Amazon API Gateway

• Amazon EC2

• Amazon RDS

What is a common challenge in microservice environments?

• Lack of programming languages.

• Requirement for a single database.

• Difficulty in optimizing server density and usage.

• Inability to run multiple versions.

How does the serverless microservice pattern help in microservice creation?

• By limiting the use of APIs.

• By requiring more client-side code.

• By reducing the barrier to creating new microservices.

• By increasing the complexity of deployment.
