I need to ssh to a non-AWS instance to push some files via Lambda. I see ssh from Lambda is possible but I can't see an example of ssh to a non-AWS instance. Is it possible?

I don't see a reason why you coudn't do it. This probably will require custom deployment package probably to bundle necessary libraries for that, such as Fabric for python.Marcin– Marcin2020-05-05 09:30:38 +00:00Commented May 5, 2020 at 9:30

It is rather unusual to use SSH from an AWS Lambda function. SSH is normally used for humans to login to a Linux computer.
If your goal is to get files onto a computer that is somewhere on the Internet, a better architecture might be to put the files in Amazon S3 and then have the remote computer 'pull' the data from S3. This offers better security and is a more 'loosely coupled' architecture.
If you do need to copy files from via an AWS Lambda function, consider using scp instead. There is a Python library available: scp · PyPI

the partner system cannot pull, I have to push via ssh only. The files are small so I don't wanna use the ETL tool and I don't wanna spin an EC2 instance just for this activity.

Some people use the Paraminko SSH library. Here's an example: Scheduling SSH jobs using AWS Lambda | AWS Compute Blog
You would want to connect to the non-aws instance via SFTP. You would want a library based on your runtime that supports SFTP.
Is their an intrinsic need to have the files be stored on a remote instance?
