If you would like to have your ssh server on your laptop and play with cpi scenarios, this blog is for you. You can connect to ssh server using cloud connector.

I am not sure about any cloud public sftp server which is available for free. If you have any, you are welcome to comment.

Apart from public sftp server, You can subscribe to any cloud(google, azure,aws) and configure your ssh server and connect to cpi. Here you wont need any cloud connector as this ssh server will be available in internet. But subscribing cloud access, you would need to provide credit card details even though you are going to use it for trial.  If you have got the cloud subscription, you can follow these blogsTry SFTP scenarios in CPI with your own SFTP server using Google Cloud | SAP Blogs and How To Setup a Test SFTP connection for Testing your CPI Iflows end to end | SAP Blogs
