- Amazon S3
Lambda@Edge functions can be triggered by events generated by Amazon CloudFront, allowing for dynamic content manipulation and delivery optimizations.
How does Lambda@Edge impact the latency of content delivery?
- Increases latency by adding additional processing overhead
- Increases latency by routing requests through central servers
- No impact on latency
- Reduces latency by executing functions closer to the end-user
Lambda@Edge reduces latency by executing functions closer to the end-user, improving response times for content delivery.
What are the limitations of Lambda@Edge compared to regular AWS Lambda functions?
- Access to fewer AWS services
- Higher memory allocation
- Longer maximum execution time
- Smaller function size limit
Lambda@Edge functions have a smaller size limit compared to regular AWS Lambda functions due to the constraints of edge computing environments.
Can Lambda@Edge functions access resources in a VPC?
- Limited access, requiring special permissions
- No, Lambda@Edge functions cannot access resources in a VPC
- Partial access, depending on VPC configuration
- Yes, Lambda@Edge functions have full access to resources in a VPC
Lambda@Edge functions execute at edge locations and do not have access to resources within a VPC due to the distributed nature of edge computing.
