概要

ownCloud Serverは、自己ホスト型のファイル同期・共有プラットフォームです。Dropboxなどのクラウドストレージサービスに近い機能を、自社サーバーやオンプレミス環境で運用できるオープンソースソフトウェアとして提供しています。2010年にFrank Karlitschekによって開発が始まり、企業・個人を問わず世界中で広く利用されています。データを自社管理することで、プライバシーとセキュリティを確保しながらチームでのコラボレーションを実現できます。現在の最新バージョンはownCloud Server 10.16.1です。

主要な特徴・機能

  • ファイル同期: デスクトップ・モバイルクライアントを通じてファイルを自動同期
  • セキュアなファイル共有: パスワード保護・有効期限付きの公開リンクによるファイル共有
  • リアルタイムコラボレーション: 複数ユーザーでのドキュメント同時編集
  • Webオフィス統合: OnlyOffice、Microsoft 365、Collabora Onlineとの連携
  • Spaces(プロジェクトフォルダ): チーム・プロジェクト単位での共有スペース管理

  • ファイル暗号化: サーバーサイドでのデータ暗号化機能
  • オンプレミス・ハイブリッド対応: 自社データセンターやハイブリッドクラウド環境に柔軟に対応
  • 拡張アプリ: プラグイン・アプリで機能を拡張可能なエコシステム
