MinIO is ideal when you need control over your data, want to host it yourself, or when you have large amounts of data that can be costly to store in the cloud. For example, a company needing to process and store sensitive customer data on their private network without relying on third-party cloud providers would choose MinIO.
You would use Google Cloud Storage over MinIO when you need a highly scalable and reliable cloud storage solution with built-in redundancy and security features, especially for large-scale applications or when using other Google Cloud services that require tight integration. A specific scenario would be a large enterprise application that uses Google Cloud Compute Engine, where you need to store and serve large amounts of data, such as videos or backups, while taking advantage of Google's global infrastructure and security capabilities.
