Nobody is impressed by that anymore; if you’re not already there, you’re behind. But once that foundation is in place, the real challenge begins: keeping systems reliable, compliant, and cost-efficient without slowing engineers down. Regulators are tightening controls, CFOs are scrutinizing cloud spend line by line, and customers expect near-zero downtime as the default. … The DevOps world in 2025 isn’t defined by whether you use IaC, CI/CD, or Kubernetes.
