I saw that chain too. I guess I do devops differently. Since I'm bootstrapping I don't have money for an ops person. So I've set about learning ufw, let's encrypt, nginx/tls termination to a service only accepting local connections to the port, etc. I see devops as the developer learning the ops side to take responsibility for the whole stack.

As a dev, I've been going through the same process for several months now. Honestly, for each of the concepts I've come across (ufw, let's encrypt, etc), you might bang your head for a few days with each one but you will eventually get it. I don't know why people make it out to be so difficult.

Stigma around ops and QA work.
