I'm not entirely sure what you want to achieve, but if you want to create new instances (e.g., EC2 instance) on the fly you should look into Infrastructure as Code (IaC) tools. I have good experience with Terraform/Packer. These tools allows you to configure new instances (e.g., EC2 or VM) and build them automatically on demand. 

Alternatively you can use Docker to create new containers automatically. You should probably use this in combination with some orchestration tools (e.g., Kubernetes, Docker Swarm) if you plan to create many new docker instances.

I hope this helps!
