Scenario: You are migrating an existing application to AWS Lambda but require a runtime environment that is not natively supported. How would you approach this using custom runtimes?
- Deploy the application on EC2 instances
- Develop a custom runtime using the AWS Lambda Runtime API
- Modify the application to use a natively supported runtime
- Utilize AWS Fargate for containerized execution
Developing a custom runtime using the AWS Lambda Runtime API allows for supporting the required runtime environment in AWS Lambda.
How does Lambda@Edge integrate with AWS CloudFront?
- By allowing you to run custom code at CloudFront edge locations
- By managing database connections
- By optimizing container deployments
- By providing machine learning models
Lambda@Edge integrates with AWS CloudFront by enabling you to run custom code at edge locations, allowing for dynamic content customization and optimization.
What are some common use cases for Lambda@Edge?
- Batch processing
- Database management
- IoT device management
- Website personalization
Lambda@Edge allows for dynamic content customization based on viewer location, device type, or other factors, enhancing user experience.
How does Lambda@Edge help improve content delivery performance?
- Executing code closer to viewers
- Increasing server capacity
- Managing networking hardware
