This pattern describes how to generate a static outbound IP address in the Amazon Web Services (AWS) Cloud by using a serverless architecture. Your organization can benefit from this approach if it wants to send files to a separate business entity by using Secure File Transfer Protocol (SFTP). This means that the business entity must have access to an IP address that allows files through its firewall.
The pattern’s approach helps you create an AWS Lambda function that uses an Elastic IP address as the outbound IP address. By following the steps in this pattern, you can create a Lambda function and a virtual private cloud (VPC) that routes outbound traffic through an internet gateway with a static IP address. To use the static IP address, you attach the Lambda function to the VPC and its subnets.
