Second Wave DevOps - The tools keep changing: “Let’s face facts: our implementation is what’s letting us down. What worked for John and Paul in 2009 is, in broad strokes, exactly what we have been asking every single DevOps practitioner to do since. We’ve replaced all the individual tools in the system multiple times (look at the CNCF Cloud Native Landscape for the evidence): less automated infrastructure, more infrastructure as code; less monitoring, more observability; less data centers, more cloud; less svn, more git; less virtual machines, more docker; less capistrano, more kubernetes; less hudson, more github actions. The problem isn’t that we haven’t optimized each individual part of the system enough. We’ve built more efficient tooling at every step. But the way the whole system is put together? The experience of using it? That’s basically identical to how it was in 2009, and it’s the reason we’re stuck."
