Platform engineering is the discipline of building internal developer platforms that improve engineering productivity. Done well, it's transformative. Done poorly, it creates bureaucracy.
The Problem Platform Engineering Solves
As engineering organizations scale, the cognitive overhead of managing infrastructure becomes a significant drag on productivity. Every team ends up solving the same problems independently. Platform engineering creates shared infrastructure that solves these problems once, well, and makes the solutions available to all teams through a well-designed developer experience.
When Platform Engineering Makes Sense
Platform engineering investments are justified when the organization has reached a scale where the cost of redundant infrastructure work across teams exceeds the cost of dedicated platform capability. Organizations with more than five to ten product teams typically find the investment worthwhile.
