Site Reliability Engineering
I was an SRE in a previous role and bought into the idea of SRE. I read the books and thought the concept was great, but after doing the role for a while and later seeing how Amazon does operations I realize that SRE is just the new ops.
The skills and tools are better and the problems are slightly different, but the process and reporting structure didn’t change. The power dynamics between SRE and application developers is unavoidable so long as the reliability for a system falls on a different team than the creators of that system.
The best way to get good at operations is to have teams where everyone has the same access, responsibilities, and titles. Reliability is discussed in the same meetings as features and design. Pagers are for everyone and tool silos are minimized.
