Use MinIO when you need a self-hosted solution with S3 compatibility or when you want to avoid vendor lock-in. For instance, if your organization has strict data governance requirements and needs to store sensitive data on-premises, MinIO can be deployed in your own infrastructure while still offering S3-like capabilities.
Backblaze B2 Cloud Storage is ideal when you need a simple, low-cost cloud storage solution without the overhead of managing your own storage infrastructure. For example, if a startup needs to store large volumes of backups or media files and wants to avoid the complexities and costs associated with setting up their own MinIO cluster, they would benefit from using Backblaze B2 for its ease of use and pricing.
