Recently, we were asked to name our top (5) DevOps “Worst Practices” (or anti-patterns). Here's what we came up with…
#1. Not looking outside the organization to see how others are solving the problem. Always building new things rather than looking for readymade solutions (open source, SaaS, or enterprise offerings) which leads to piles of technical debt & inevitable snowflake infrastructures.
#2. Not building easy tools that the rest of the company can use. We must never forget who we are serving. Developers are our customers too.
#3. Not treating DevOps as a shared responsibility. It needs to be embedded into the engineering organization, not relegated to a select few individuals. “DevOps” is more of a philosophy than a job title.
#5. Never ever commit to `master`. We don't do it in regular software projects, we shouldn't do it for ops. Everyone should be following the standard Git Workflow on their Infrastructure Code (Feature Branching, Pull Requests, Code Reviews, CI/CD). This increases transparency and helps the rest of the team stay up to date with everything going on.
