What are the best practices for using AWS Lambda with VPC?

When using AWS Lambda with a VPC, consider the following best practices: 1. Use a VPC endpoint for S3 access. 2. Minimize the number of security groups. 3. Optimize your Lambda function's timeout settings. 4. Use environment variables for configuration.

Why should I use a VPC endpoint for S3?

Using a VPC endpoint for S3 allows your Lambda function to access S3 without needing an internet gateway, enhancing security and reducing latency.

How can I optimize my Lambda function's timeout settings?

To optimize timeout settings, analyze the execution time of your function and set the timeout to just above the average execution time, ensuring it can handle peak loads without unnecessary delays.

What are the implications of having too many security groups?

Having too many security groups can complicate network management, lead to performance issues, and increase the risk of misconfigurations that could expose your resources.
