I\'m new to Terraform, but how to say run it on a regular server? Is it possible? I am talking - regular on premises machine
The question is vaguely understandable but,
If it means that you want to write Infrastructure-as-Code
for your personal on premises servers the answer is NO. Refer to Martin Atkins' answer.
If it means that you want to ssh into your on premises servers and execute terraform routines (plan, apply, destroy etc.), the answer is YES.
