Feature: Automate Fixed IP Assignment Using NAT Instances for Load Testing

[tani-shi]

Is your feature request related to a problem? Please describe.
When the server being load-tested is in a different account and has a firewall set up, it is necessary to fix the IP. Currently, we are using a NAT Gateway, but when the post data becomes large, the cost becomes quite high. Therefore, we would like to avoid using a NAT Gateway if possible.

Describe the feature you'd like
Since it is difficult to implement a header authentication mechanism on the server being load-tested, we would like an automated system where a NAT instance is launched during the load test, enabling fixed IP addresses.

Additional context

Thank you @tani-shi, for requesting this enhancement. To better understand your needs, could you please provide more details about your current server setup and the test protocol you're using? Although NAT instances might be more cost-effective for your situation, they come with certain overheads and limitations that could become more challenging to manage over time.

Thank you for your prompt response.

To provide more details:

• We need to make HTTP requests to GCP, which requires setting up firewall IP limitations.
• Currently, we have built Distributed Load Testing (DLT) on private subnets that are routed through a NAT Gateway.
• The best approach for us would be to launch NAT instances only while load-testing tasks are executing.

Hi @tani-shi
Thanks for providing the details, we will review the feature/requirements and currently have added this task to our backlog.
