Lambda static outbound IP address without NAT gateway


My lambda use case deals with outbound connections. I would like to have a static IP address, so I can whitelist them.

Since my use case deals with outbound connections, I can't use a load balancer here.

NAT gateway can be associated with elastic IP address. But cost is a barrier.

At the moment, I'm using a NAT EC2 instance for having a static IP address.

Is there a better way?

p.s. My lambda function is triggered by SQS. And my function require access to S3 and DynamoDB. No other access required.

Unfortunately no, the only way at the moment to get a fixed IP on outgoing requests for lambda is to be running in a VPC with a NAT gateway or NAT instance.
