NEW

An open-source, high-performance, S3-compatible object storage server for on-premises and cloud deployments.

DESCRIPTION

MinIO provides S3-compatible object storage with a focus on performance, simplicity, and scalability. It supports erasure coding, bitrot detection, encryption, versioning, tiering, and multi-site replication. MinIO is Kubernetes-native with an Operator for automated deployment and scaling. It underpins data lakes, AI/ML datasets, backups, and artifact storage where portability and S3 API compatibility are required. Its lightweight footprint enables high throughput on commodity hardware.

TOP QUESTIONS

What is MinIO used for?

MinIO provides S3-compatible object storage for data lakes, AI/ML datasets, backups, logs, and application assets, running on-premises or in the cloud.

Category: Overview

How does MinIO compare to Amazon S3?

MinIO implements the S3 API for compatibility but runs wherever you deploy it. S3 is a managed AWS service; MinIO offers portability and local control.

Category: Comparison

What are MinIO’s key features?

Key features include erasure coding, bitrot detection, encryption, versioning, replication, object locking, and Kubernetes-native operations via the MinIO Operator.

Category: Features

Is MinIO suitable for production at scale?

Yes. MinIO scales horizontally with distributed deployments and erasure coding, supporting high throughput on commodity hardware.

Category: Scalability

How is MinIO secured?

MinIO supports TLS, server-side encryption, KMS integration, IAM-style policies, and bucket/object-level access management.

Category: Security

What are common mistakes when deploying MinIO?

Under-provisioning network and disks, mixing heterogeneous hardware in the same set, and skipping erasure coding/parity planning are common pitfalls.

Category: Mistakes

Does MinIO support multi-tenancy?

Yes. Tenants can be isolated with separate namespaces, credentials, and policies, especially via the Kubernetes Operator.

Category: Architecture

How does MinIO handle data durability?

MinIO uses erasure coding and bitrot detection to tolerate multiple drive failures and ensure object integrity.

Category: Reliability

What are notable MinIO alternatives?

Alternatives include Ceph, Apache Ozone, and managed services like Amazon S3 or Google Cloud Storage.
