  • 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.
