+## Milvus with External Object Storage
+
+As of https://github.com/minio/minio/releases/tag/RELEASE.2022-10-29T06-21-33Z, the MinIO Gateway and the related filesystem mode code have been removed. It is now recommended to utilize the `externalS3` configuration for integrating with various object storage services. Notably, Milvus now provides support for popular object storage platforms such as AWS S3, GCP GCS, Azure Blob, Aliyun OSS and Tencent COS. 
+
+The recommended configuration option for `externalS3.cloudProvider` includes the following choices: `aws`, `gcp`, `azure`, `aliyun`, and `tencent`. Here's an example to use AWS S3 for Milvus object storage:
+
+```
+minio:
+  enabled: false
+externalS3:
+  enabled: true
+  cloudProvider: aws
+  host: s3.aws.com
+  port: 443
+  useSSL: true
+  bucketName: <bucket-name>
+  accessKey: <s3-access-key>
+  secretKey: <s3-secret-key>
+```
+
+
