Top 10 Questions for Derrick Helper Interview

1. Can you describe your experience with AWS Lambda?

In my previous role, I was responsible for designing and implementing serverless architectures using AWS Lambda. I have experience with creating Lambda functions, using the AWS SDK for Node.js, and configuring event triggers. I am also familiar with the AWS Lambda console, the AWS CLI, and the Serverless Framework.

2. How would you debug a Lambda function that is not working as expected?

Logging and monitoring

• Use CloudWatch Logs to examine the function’s logs and identify any errors or exceptions.
• Enable X-Ray tracing to visualize the function’s execution flow and identify potential bottlenecks.

Code inspection

• Review the function’s code to ensure it is syntactically correct and error-free.
• Check the function’s dependencies and ensure they are compatible with the current runtime environment.

3. What are the best practices for writing efficient and scalable Lambda functions?

• Keep functions small and focused on a single purpose.
• Use async/await patterns to avoid blocking operations.
• Minimize the use of global variables and external dependencies.
• Monitor function performance and adjust memory and timeout settings as needed.
• Consider using serverless frameworks, such as Serverless Framework or Chalice, to streamline development and deployment.

4. How would you handle a situation where a Lambda function is taking too long to execute?

• Analyze the function’s logs and identify the source of the delay.
• Consider refactoring the function to improve its performance.
• Increase the function’s memory and timeout settings to allow for more processing time.
• Explore using a different runtime environment or deployment model, such as containers or Fargate, if necessary.

5. What is the role of API Gateway in serverless architectures?

API Gateway is a fully managed service that allows you to create and manage APIs that front-end your serverless applications. It provides features such as:

• Authentication and authorization
• Traffic management
• Caching
• Monitoring

6. How would you integrate a Lambda function with a relational database?

• Use the AWS SDK for Node.js to connect to the database.
• Create a Lambda function that performs the necessary database operations.
• Configure the Lambda function to be triggered by an event, such as a new record in the database.

7. What are the benefits of using managed services, such as DynamoDB, in serverless architectures?

• Reduced operational overhead
• Automatic scaling
• High availability
• Built-in security and compliance

8. How would you design a serverless architecture for a highly scalable web application?

I would use a combination of AWS services, such as:

• AWS Lambda for the application logic
• API Gateway for the API front-end
• DynamoDB for the database
• S3 for static assets
• CloudFront for content delivery

9. What are the challenges of developing serverless applications?

• Debugging can be more difficult than with traditional applications.
• Managing multiple services can be complex.
• Cost optimization can be challenging.

10. What are the trends and future of serverless computing?

• Increased adoption of serverless architectures for enterprise applications
• Development of new serverless frameworks and tools
• Expansion of serverless offerings from cloud providers
