+## nextcloud VS owncloud-ocis
+
+### ownCloud Infinite Scale (oCIS)
+1. ownCloud Infinite Scale (oCIS)是新一代的ownCloud，前后端都重构了，体积更小，界面更加现代化，动画也挺流畅，支持了复制和剪切，可以在线查看和编辑Markdown，支持电脑和移动客户端同步。
+2. 它不依赖于PHP或数据库这样的外部软件包，消除了使用它们所带来的所有麻烦。凭借其现代架构，Infinite Scale 为云基础架构部署提供所有部署模型，并优化缩放设置，给投入带来最佳产出。
+3. 目前新的Web界面还没有支持中文
+4. 支持 docker 部署， 详细文档 [owncloud/ocis](https://hub.docker.com/r/owncloud/ocis)
+### nextcloud 
+1. NextCloud是用于基于Linux系统的开源云存储平台。
+2. 支持Postgresql，Sqlite，MariadB，MySQL和Oracle数据库。
+3. NextCloud于2016年推出，ownCloud于2010年1月发布，但第一个Beta版本于2010年3月启动。并于2012年发布了OwnCloud。NextCloud于2016年推出，当时Frank Karlitschek分叉了OwnCloud创建NextCloud。
+4. NextCloud提供了防止蛮力攻击，流量限制，速率限制，密码管理，内容安全策略和许多其他安全选项的保护。
