# Federation Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) *Federation feature is deprecated and should be avoided for future deployments*

This document explains how to configure MinIO with `Bucket lookup from DNS` style federation.

## Get started

### 1. Prerequisites

Install MinIO - [MinIO Quickstart Guide](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html).

	}

	// Bucket federation is 'true' only when IAM assets are not namespaced
	// per tenant and all tenants interested in globally available users
	// if namespace was requested such as specifying etcdPathPrefix then
	// we assume that users are interested in global bucket support
	// but not federation.
	globalBucketFederation = etcdCfg.PathPrefix == "" && etcdCfg.Enabled

- Temporary credentials have a limited lifetime, there is no need to rotate them or explicitly revoke them. Expired temporary credentials cannot be reused.

## Identity Federation

			// No IPs seem to intersect, this means that bucket exists but has
			// different IP addresses perhaps from a different deployment.
			// bucket names are globally unique in federation at a given
			// path prefix, name collision is not allowed. We simply log
			// an error and continue.
			bucketsInConflict.Add(bucket)

	// Add/update buckets that are not registered with the DNS

Kubernetes as stateful containers with local storage (JBOD/JBOF) mapped as persistent local volumes. This architecture enables multi-tenant MinIO, allowing isolation of data between customers.

MinIO also supports multi-cluster, multi-site federation similar to AWS regions and tiers. Using MinIO Information Lifecycle Management (ILM), you can configure data to be tiered between NVMe based hot storage, and HDD based warm storage. All data is encrypted with per-object key.
