The deployment workflow shows which cloud resources are created on Open Telekom Cloud. In this example, a virtual router, network, port, floating IP, and a Virtual Machine (VM) are created:

In the console of Open Telekom Cloud, you can see these resources are created as well.

After the VM is created, the orchestration engine tests the SSH connection to the VM:

During the deployment, the orchestration engine creates a security group that allows it to access the VM. Then it uses Ansible to zip and copy the HelloWorld script to the VM (via SSH), and executes it there. The script prints out the Hello World! text in the deployment logs. After the deployment completes, the orchestration engine deletes the security group to prevent any further access to the VM.
