Nextcloud

Nextcloud is a powerful self-hosted cloud storage and collaboration platform that serves as a privacy-focused alternative to services like Dropbox, Google Drive, and Microsoft 365. It enables you to sync files across devices, share documents with granular permissions, and collaborate in real-time. Beyond file storage, Nextcloud offers an extensive app ecosystem including calendar, contacts, email client, video conferencing, and office suite integration. By self-hosting Nextcloud, you maintain complete control over your data while enjoying enterprise-grade features.

Nextcloud's performance is directly tied to your server resources. The platform runs on PHP with a database backend (MySQL, MariaDB, or PostgreSQL) and constantly handles file operations, user sessions, and background tasks simultaneously. RAM is critical for generating file previews, running full-text search indexing, and managing concurrent user connections. CPU power affects file encryption/decryption speed, document conversion, and real-time collaboration features. Storage I/O speed impacts file transfer rates and database query performance.
