Most cloud failures happen due to over-engineering. Start simple, scale later.
When teams move to the cloud, the common trap is trying to build a “perfect future-proof architecture” from day one. In reality, this leads to complexity, cost overruns, and slower delivery.

The most reliable cloud systems start simple:

• One VPC per environment
• Managed services where possible (BigQuery, Cloud SQL, Cloud Run)
• Automated monitoring from day one (Cloud Logging + Alerting)
• Clear separation of dev / test / prod

As the product scales, the architecture should evolve intentionally, not by adding complexity every sprint.

The best cloud architects are not the ones who add more services —
but the ones who know what to skip.
