MinIO 是全球領(lǐng)先的對象存儲先鋒势就，以 Apache License v2.0 發(fā)布的對象存儲服務(wù)器，是為云應(yīng)用和虛擬機(jī)而設(shè)計的分布式對象存儲服務(wù)器。在標(biāo)準(zhǔn)硬件上洋腮，讀/寫速度上高達(dá)183GB/s和171GB/s。它與 Amazon S3 云存儲服務(wù)兼容手形。 它最適用于存儲非結(jié)構(gòu)化數(shù)據(jù)啥供，如照片、視頻库糠、日志文件伙狐、備份和容器/虛擬機(jī)映像。 對象的大小可以從幾KB 到最大5TB瞬欧。
- 對象存儲贷屎，兼容Amazon S3協(xié)議
- 安裝運維相對簡單，開箱即用
- 后端除了本地文件系統(tǒng)黍判，還支持多種存儲系統(tǒng)豫尽，目前已經(jīng)包括 OSS
- 原生支持bucket事件通知機(jī)制
- 可通過多節(jié)點集群方式，支持一定的高可用和數(shù)據(jù)容災(zāi)
- 有WEB管理界面和CLI顷帖，可以用于測試或者管理
- 公開bucket中的數(shù)據(jù)可以直接通過HTTP獲取
MinIO是一個非常輕量的服務(wù),可以很簡單的和其他應(yīng)用的結(jié)合美旧，類似 NodeJS, Redis 或者 MySQL。
MinIO支持多種靈活的部署方式贬墩，支持Docker Compose榴嗅、Docker Swam、Kubernetes等陶舞，詳見官網(wǎng)：https://docs.min.io/docs/minio-deployment-quickstart-guide.html或者https://min.io/download#/linux
