 Erasure code protects data from multiple drives failure unlike RAID or replication. For eg RAID6 can protect against 2 drive failure whereas in Minio erasure code you can lose as many as half number of drives and still the data remains safe. Further Minio's erasure code is at object level and can heal one object at a time. For RAID, healing can only be performed at volume level which translates into huge down time. As Minio encodes each object individually with a high parity count. Storage servers once deployed should not require drive replacement or healing for the lifetime of the server. Minio's erasure coded backend is designed for operational efficiency and takes full advantage of hardware acceleration whenever available.

 ## Cloud Scale Deployment
 For large scale multi-tenant Minio deployments, we recommend using one of the popular container orchestration platforms, e.g. Kubernetes, DC/OS or Docker Swarm. Refer [this document](https://docs.minio.io/docs/minio-deployment-quickstart-guide) to get started with Minio on orchestration platforms.

 In a typical modern infrastructure deployment, application, database, key-store, etc. already live in containers and are managed by orchestration platforms. Minio brings robust, scalable, AWS S3 compatible object storage to the lot.
