You have six engineering teams each building on Google Cloud in their own way. One spawned fifty projects under the same billing account with no folder structure. Another granted roles/editor to a service account that has access to your production BigQuery datasets. A third set up a VPN that routes production traffic through a shared-VPC project managed by someone who left the company six months ago.
This is not a hypothetical. It is what PT CPI finds during almost every cloud assessment for regulated enterprises in Indonesia and ASEAN. The cost of fixing this after production workloads are running is 3–5x higher than getting the foundation right upfront.
Why the first three months decide your next three years
The decisions you make during landing zone design are the decisions you live with until a reorganization forces a cleanup. Folder hierarchy determines how IAM policies propagate. Network topology determines whether you can connect to your on-premises trading systems without exposing management planes. Logging and backup configurations determine whether your audit team can produce evidence for OJK or BI before a deadline, or whether they have to reconstruct it from Cloud Logging exports that were never configured.
PT CPI treats the landing zone as the contract between engineering, security, finance, and compliance. It defines who can deploy what, where data may live, and how incidents are detected. When done properly, each new project inherits guardrails instead of renegotiating basics.
Compliance is not retrofittable
For FinTech and banking workloads, environment segregation and provable controls must be designed in—not bolted on before an audit. PT CPI has structured landing zones for institutional clients where the architecture record produced during implementation was the same document submitted to counterparty due diligence. That is the standard: compliance evidence as a by-product of delivery, not a separate project phase.
If your team is about to start a GCP migration or expansion, invest the first sprint in foundation architecture. PT CPI aligns landing zone delivery with partner onboarding timelines so your procurement and engineering teams see one coherent plan.
