> DevOps is a relatively new set of practices that automates the processes between software development and infrastructure teams. Tools like Terraform, Puppet and Docker have been created to give engineers a way to automatically deploy servers and code. If by "relatively new" you mean "something sysadmins were using fifteen or twenty years ago". Puppet stems from cfengine, which had its first version well back into '90s, and Puppet itself was introduced in 2005. Docker is a mix of package management systems like RPM or DPKG (again, '90s) with something that is just extended chroot(), and we had this extension as far back as 2004 (Solaris Zones) or even 2000 (FreeBSD jails). The tooling was not invented by DevOps movement by any stretch.
