    What is the real difference between a sysadmin and a devops?

      Luix here is the link to the promised article on your question!

    It is not a question that has a short answer, but the difference at first glance seems none. However, a DevOps is a mixture of Sysadmin and Developer whose function is precisely to eliminate the barriers between both profiles. Therefore, you must have knowledge of both the software and the infrastructure where it will be hosted. While the Sysadmin is like the highest level that an IT Specialist can reach who, in addition to Infrastructures and Processes, also knows programming without the need for him to be an expert in that area.

    The truth is that the question was good and I promise to do an article about it.

    Although DevOps is in the middle between Sysadmin and Developer, its main function is to automate deployments. Large companies make thousands of deployments daily and without this automation it is completely impossible to meet the needs of millions of users of these companies where a crash or a bug must be solved in minutes.
    A DevOps can get closer to the work of a sysadmin, when working in the cloud using Infrastructure as a code, where you can have scripts to create the entire infrastructure of the company from scratch.
