MinIO
Summary
What it is
An open-source, S3-compatible object storage server designed for high performance and self-hosted deployment.
Where it fits
MinIO is the primary open-source alternative to AWS S3. It enables organizations to run the same S3 workloads on-premise, at the edge, or in any cloud — breaking vendor lock-in while keeping the S3 API contract.
Misconceptions / Traps
- MinIO implements the S3 API but is not AWS S3. Some AWS-specific features (S3 Select, S3 Inventory) may not be available or behave differently.
- MinIO provides strict read-after-write consistency by default — stronger than historical AWS S3 behavior.

Definition
What it is
An open-source, S3-compatible object storage server designed for high performance and self-hosted deployment.
Why it exists
Organizations need S3-compatible storage they can run on their own infrastructure — on-premise, at the edge, or in any cloud — without depending on a single vendor.
Primary use cases
Self-hosted data lakes, on-premise lakehouse storage, CI/CD artifact storage, S3-compatible development and testing environments.
