Minio is a lightweight, AWS S3 compatible object storage server. It is best suited for storing unstructured data such as photos, videos, log files, backups, VM and container images. Size of an object can range from a few KBs to a maximum of 5TB. Minio server is light enough to be bundled with the application stack, similar to NodeJS, Redis and MySQL.
Minio supports distributed mode. In distributed mode, you can pool multiple drives (even on different machines) into a single object storage server. This chart bootstraps Minio deployment on a Kubernetes cluster using the Helm package manager.
Amazon S3 API is the de facto standard for object storage. Minio implements Amazon S3 v2/v4 API. Use Minio SDK, Minio Client, AWS SDK, and AWS CLI to access Minio server.
Minio protects data against hardware failures using erasure code and bitrot detection. You may lose up to half the number of drives and still recover from it. Data protection code is accelerated using SIMD instructions on x64 and ARM CPUs.
Minio server can tolerate up to (N/2)-1 node failures in a distributed setup. In addition, you may configure Minio server to continuously mirror data between Minio and any Amazon S3 compatible server.
Minio server triggers Lambda functions through its AWS SNS/SQS compatible event notification service. Supported targets are message queues such as Kafka, NATS, AMQP, MQTT, Webhooks, and databases such as Elasticsearch, Redis, Postgres, and MySQL. Thumbnail generation, OCR and audit compliance are good examples of lambda computing.
Minio provides confidentiality, integrity and authenticity assurances for encrypted data with negligible performance overhead. Both server side and client side encryption are supported using AES-256-GCM, ChaCha20-Poly1305, and AES-CBC. Encrypted objects are tamper-proofed with AEAD server-side encryption.
In addition to Minio’s own filesystem and erasure code backends for DAS and JBODs, external storage backends such as NAS, Google Cloud Storage, and Azure Blob Storage are supported as well.
