How does AWS Lambda handle networking when integrated with a VPC?
- AWS Lambda creates elastic network interfaces (ENIs)
- AWS Lambda relies on the internet for networking
- AWS Lambda shares network resources with other services
- AWS Lambda uses its own dedicated network
When integrated with a VPC, AWS Lambda creates elastic network interfaces (ENIs) to allow functions to access resources within the VPC securely.
What security considerations should be taken into account when using VPC integration with AWS Lambda?
- Configuring proper security group rules
- Disabling VPC altogether
- Ignoring security groups
- Using default VPC settings
Configuring proper security group rules is crucial for controlling inbound and outbound traffic to and from AWS Lambda functions within the VPC, enhancing security.
What are the best practices for optimizing performance when using VPC integration with AWS Lambda?
- Avoid using VPC altogether
- Increase function timeout settings
- Minimize cold starts by allocating more memory
- Use smaller subnets within the VPC
Minimizing cold starts by allocating more memory to AWS Lambda functions is a best practice for optimizing performance when integrated with a VPC.
VPC integration with AWS Lambda allows functions to access resources within the __________.
- IAM role
- Internet Gateway
- Public subnet
- Virtual Private Cloud
VPC integration with AWS Lambda allows functions to access resources within the Virtual Private Cloud (VPC), providing secure and private connectivity to resources such as Amazon RDS or Amazon EC2 instances.
What is the primary benefit of using VPC integration with AWS Lambda?
- Increased scalability of Lambda functions
- Reduced cost of function execution
- Securely access resources within a VPC
- Simplified management of Lambda functions
The primary benefit of VPC integration with AWS Lambda is the ability to securely access resources within the connected Virtual Private Cloud (VPC), ensuring data privacy and network isolation.
What are the potential drawbacks of using VPC integration with AWS Lambda?
- Cold start latency
- Complexity in setup
- Increased cost
- Limitation on available IP addresses
When using VPC integration with AWS Lambda, cold start latency can increase due to the time required to configure networking resources within the VPC.
How does VPC configuration impact the networking capabilities of AWS Lambda functions?
- Enables access to private resources
- Enhances security
- Increases latency
- Limits outgoing internet access
VPC configuration allows AWS Lambda functions to access private resources within the VPC, such as databases and other services not exposed to the public internet.
In what scenarios would you consider using VPC integration with AWS Lambda?
- Accessing private resources
- Enhanced security requirements
- Handling sensitive data
- Need for granular network controls
VPC integration is suitable when AWS Lambda functions need to access private resources within the VPC, such as databases, caching layers, or internal APIs.
When configuring VPC integration for AWS Lambda, you must specify one or more __________ for the function.
- Route tables
- Security groups
- Subnets
- VPC endpoints
When configuring VPC integration for AWS Lambda, you must specify one or more subnets for the function to use within the Virtual Private Cloud (VPC).
AWS Lambda functions with VPC integration may experience increased __________ due to networking overhead.
- CPU utilization
- Latency
- Memory usage
- Throughput
AWS Lambda functions with VPC integration may experience increased latency due to networking overhead introduced by routing traffic through the Virtual Private Cloud (VPC).
