All the steps involved to create instance, additional requirements and the solution for the speed issue are documented here in this blog with the screen shots and examples.
Project:
Go to https://dashboard.eu-de-1.cloud.sap/
Login using global credentials.
When there is no existing project available for you, you should create Project as a first step. You can fill the details based on your project requirement while creating the project, this is required admin’s approval. Once it is approved, you can start creating the instances.
Resource Management:
Click Resource management.

Security group can be default. Key pair and private network can be chosen which is created earlier.
Floating IP:
Once the instance is created, the floating ip should be attached to make visibility to external access.
Access the VM:
To access the VM, you can use VNC console. Once you click on the VNC Console, the 2-factor authentication window will be prompted. Here the user id will be by default your global user id and password should be combination of your pin(4-6 digit) and RSA token. In case, you don’t remember your pin then try to rest by https://netsec.wdf.sap.corp/sdi_selfservice/sdi_change_pin.cgi
Nova-compute Password:Once you are authenticated by 2-factor authentication(secure id), you will be redirected to the VM.
Default username is Administrator and the password should be Nova password that you should generate.
You can generate Nova-password by following the steps given in this link https://documentation.global.cloud.sap/blog/2019/06/05/nova-password.html
Once you download the Nova password.exe, you can execute the below steps in Windows power shell
{
.\openrc.ps1 <this can be downloaded by following next section>
.\nova-password.exe –private-key-path <ssh file path> <instance name>
}
When you execute above 2 commands, you will be prompted to enter passwords.
Open stack Password will be your Global password and Private key password is the password you used to generate ssh file.
End of successful running, you will get Nova password that can be used to login VM.
