How do I configure AWS Lambda functions to access resources in a VPC?

To configure AWS Lambda functions to access resources in a VPC, you need to specify the VPC settings in the Lambda function configuration. This includes selecting the VPC, subnets, and security groups that the function will use.

What are the steps to set up the VPC configuration for my Lambda function?

First, go to the AWS Lambda console, select your function, and then choose 'Configuration'. Under 'VPC', select 'Edit', and then choose your VPC, subnets, and security groups. Finally, save the changes.

Are there any limitations I should be aware of when using Lambda with VPC?

Yes, when a Lambda function is configured to run within a VPC, it cannot access the internet unless you set up a NAT gateway or NAT instance. Additionally, cold starts may be longer due to the VPC configuration.

Can I use Lambda with multiple VPCs?

No, a single Lambda function can only be associated with one VPC at a time. However, you can create multiple Lambda functions, each associated with different VPCs.
