Infrastructure as code for customer data

Build vs. buy in the age of AI


Customer data infrastructure has become one of the most critical and most fragile layers in the modern stack.


Event streams power analytics, activation, and AI systems. But many teams still manage tracking plans, pipelines, identity logic, and governance through UI clicks, manual fixes, and scattered documentation.


That approach does not scale.


This guide explains why treating customer data infrastructure as versioned, testable code improves reliability, traceability, and speed. More importantly, it shows why Infrastructure as Code is the prerequisite for safe AI assistance.
