Why It's Hard
The Three Root Causes of Multi-Cloud Overspend
Most GCP and AWS cost overruns aren't caused by engineering mistakesβthey're caused by missing context, delayed signals, and fragmented ownership. Running both clouds compounds every one of these. Here's what typically goes wrong.
π
Invisible Billing Complexity
GCP billing spans Compute Engine, BigQuery, Cloud Storage, and networking egress; AWS billing spans EC2, S3, data transfer, and dozens more services β each with its own console. Without a unified view across both, finance teams lack the context to question or challenge spend patterns.
β±οΈ
Delayed Cost Signals
By the time a billing spike appears in a monthly report, weeks of avoidable spend have already occurred. GCP and AWS cost optimization requires real-time alerting β including Slack alerts the moment a budget or anomaly crosses a threshold β not retrospective analysis.

Fragmented Ownership
When no single team owns spend accountability across both clouds, optimization recommendations sit in backlogs. Clear cost ownership, structured multi-cloud billing management, and prioritized action lists are essential to turning insight into savings.
