What is the primary role of deployment packages in AWS Lambda function creation?
- Bundling code and dependencies
- Configuring networking
- Generating logs
- Managing server resources
Deployment packages in AWS Lambda serve the primary role of bundling the function code along with any dependencies required for execution.
How does AWS Lambda handle the execution environment for your function?
- It delegates execution environment management to users
- It manages the execution environment automatically
- It requires manual configuration of execution environment
- It restricts access to the execution environment
AWS Lambda automatically manages the execution environment for your function, including provisioning resources and scaling based on demand.
What role do environment variables play in AWS Lambda function development?
- Controlling network access
- Defining function behavior
- Managing compute resources
- Storing configuration settings
Environment variables in AWS Lambda are commonly used for storing configuration settings such as API keys, database connection strings, and other parameters necessary for the function's operation.
How does IAM role and permissions affect the behavior of an AWS Lambda function?
- Define the function's runtime environment
- Determine what AWS services the function can access
- Manage the function's memory allocation
- Specify the function's timeout duration
IAM roles and permissions determine the AWS services and resources that the Lambda function can access, ensuring appropriate access controls and security.
What are some common methods for handling dependencies in AWS Lambda functions?
- Installing dependencies at runtime
- Packaging dependencies with the function code
- Sharing dependencies across multiple functions
- Storing dependencies in a separate S3 bucket
One common method for handling dependencies in AWS Lambda functions is to package them along with the function code, typically using tools like AWS SAM or AWS CLI.
What considerations should be made for integrating AWS Lambda functions with API Gateway?
- Authentication and authorization
- Choosing a database service
- Hardware requirements
- Network bandwidth limitations
Securely integrating AWS Lambda functions with API Gateway involves implementing authentication and authorization mechanisms to control access to APIs and functions.
How can you optimize AWS Lambda functions for better performance and cost efficiency?
- Implementing code optimizations
- Increasing memory allocation
- Running functions continuously
- Using larger instance types
Optimizing code by minimizing execution time, reducing unnecessary dependencies, and implementing best practices can improve AWS Lambda function performance and reduce costs by reducing the time and resources required for execution.
When creating AWS Lambda functions, deployment packages typically consist of the function's code and its __________.
- Configuration
- Dependencies
- Documentation
- Permissions
Deployment packages for AWS Lambda functions typically consist of the function's code and its dependencies or required libraries.
Environment variables in AWS Lambda can be utilized to configure settings such as __________.
- API endpoints
- Billing details
- Code syntax
- Encryption keys
Environment variables in AWS Lambda can be utilized to configure settings such as API endpoints, allowing for flexibility in the function's behavior.
To ensure security and access control, AWS Lambda functions are associated with __________ that define their permissions.
- API keys
- IAM roles
- SSH keys
- SSL certificates
AWS Lambda functions are associated with IAM roles that define their permissions, ensuring security and access control based on defined policies.
