What are custom event sources in AWS Lambda?
- Built-in AWS services
- External services or applications
- Lambda-managed sources
- On-premises data centers
Custom event sources in AWS Lambda refer to external services or applications that can trigger the execution of Lambda functions by emitting custom events.
How do custom event sources differ from standard event sources in AWS Lambda?
- Customizability
- Built-in compatibility
- Scalability
- Performance
Custom event sources offer more flexibility and customization options compared to standard event sources, allowing developers to define their own event formats and sources.
What is the significance of integrating custom event sources with AWS Lambda?
- Cost reduction
- Extensibility
- Latency reduction
- Security enhancement
Integrating custom event sources with AWS Lambda extends the capabilities of Lambda functions, allowing them to respond to a wider range of events from external sources.
What are some examples of custom event sources that can trigger AWS Lambda functions?
- AWS Step Functions, AWS Glue, AWS CodePipeline
- Amazon API Gateway, Amazon CloudFront, Amazon S3
- Amazon EC2, Amazon RDS, Amazon DynamoDB
- Amazon SQS, Amazon SNS, Amazon Kinesis
Custom event sources for AWS Lambda include services like Amazon SQS, Amazon SNS, and Amazon Kinesis, allowing you to trigger functions in response to messages, notifications, and streaming data.
What are the advantages of using custom event sources for AWS Lambda over traditional event sources?
- Built-in integration
- Flexibility and extensibility
- Higher reliability
- Lower latency
The advantages of using custom event sources for AWS Lambda over traditional event sources include flexibility and extensibility, allowing you to integrate with a wide range of services and systems beyond those natively supported by AWS Lambda.
In what scenarios would you recommend using custom event sources with AWS Lambda?
- Database management
- Integration with third-party services
- Internal service communication
- Load balancing
Custom event sources in AWS Lambda are recommended when integrating with third-party services that generate events not natively supported by AWS services.
AWS Lambda functions are triggered by various __________ such as API Gateway, S3 events, and CloudWatch Events.
- Events
- Jobs
- Messages
- Triggers
AWS Lambda functions are triggered by various events such as API Gateway requests, S3 bucket events, and CloudWatch Events, which invoke the execution of the function.
What are the best practices for monitoring and logging custom event sources in AWS Lambda?
- Disable logging to reduce overhead
- Manual logging in function code
- Use third-party logging services
- Utilize CloudWatch Metrics and Logs
Best practices for monitoring and logging custom event sources in AWS Lambda include utilizing CloudWatch Metrics and Logs to track function invocations, errors, and performance metrics.
Custom event sources enable AWS Lambda functions to respond to __________.
- Built-in events
- Custom events
- System events
- Third-party events
Custom event sources enable AWS Lambda functions to respond to custom events, allowing for integration with various services and applications.
When configuring custom event sources, it's essential to define the appropriate __________ for event processing.
- Event mapping
- Execution environment
