Server for Nextcloud: your own cloud without subscriptions

To create your own Nextcloud cloud without subscriptions, with full control over data, high performance, and scalable storage, the ideal choice is a dedicated server (nextcloud dedicated server). It ensures stable operation, reliable backups, and seamless integration with office suites like OnlyOffice/Collabora.

In a world where data privacy and independence from large corporations are becoming increasingly valuable, your own Nextcloud on a dedicated server offers an uncompromising solution. It's not just a file-sharing service, but a full-fledged platform for collaboration, calendars, contacts, video calls, and much more, where you remain the sole owner and administrator of your data.

Why Nextcloud on a Dedicated Server is the Best Choice for Your Self-Hosted Cloud?

When it comes to creating a self-hosted cloud solution like Nextcloud, infrastructure choice plays a key role. Many start with a VPS, but as needs and user numbers grow, the limitations of virtual servers become apparent. A Nextcloud dedicated server offers several advantages that make it the optimal choice:

• Full Control and Privacy: You own the entire infrastructure, from hardware to software. No third-party restrictions, only your security and data storage policies.
• High Performance: All server resources (CPU, RAM, disk subsystem, network channel) are exclusively available to your Nextcloud. This is critical for large data volumes, many concurrent users, or intensive file operations.
• Scalable Storage (Storage-Heavy): Dedicated servers allow for installing tens of terabytes of HDDs or high-speed NVMe drives, as well as flexible RAID array configuration.
• Reliability and Security: The ability to fine-tune firewalls, intrusion detection systems, and physical access to hardware (in the case of colocation, although for Valebyte it's a managed server) provides an unprecedented level of security.
• Long-Term Cost Savings: For large data volumes and a significant number of users, the cost of a dedicated server often turns out to be lower than comparable cloud services or VPS with similar characteristics.

Nextcloud Hosting: VPS or Dedicated – What to Choose for Your Nextcloud?

The choice between a VPS and a dedicated server for Nextcloud hosting depends on your current and future needs. Let's look at the main differences:

For a serious own Nextcloud, especially if you plan to store large volumes of data, actively use synchronization and collaboration, a dedicated server is a more predictable and reliable solution. You can read more about when a cloud might be unnecessary in our article: Cloud vs Dedicated: when the cloud is not needed.

Storage Requirements: Storage-Heavy, RAID, and Disk Selection for Nextcloud Dedicated Server

Nextcloud, by its nature, is a file storage solution, so the disk subsystem is its heart. A storage-heavy configuration for a Nextcloud dedicated server implies not only large capacity but also the right type of disks combined with a RAID array.

• Capacity: Start with plenty of room. If 10 users store 100 GB each, you already need 1 TB. Add space for backups, databases, OS, and future growth. It's recommended to start with 2-4 TB for medium teams.
• Disk Type:
  • NVMe SSD: Maximum read/write speed. Ideal for active users, Nextcloud databases, caching, and applications (OnlyOffice/Collabora). More expensive, but provides outstanding performance.
  • SATA SSD: Good balance between speed and price. An excellent option for primary storage if NVMe is too expensive, but performance higher than HDD is required.
  • SATA HDD: The most economical option for large volumes. Suitable for cold storage, archives, or when the budget is severely limited. I/O performance is significantly lower than SSDs.
• RAID Arrays: Critically important for fault tolerance and performance.
  • RAID 1 (mirroring): Two disks, full data copy. Provides fault tolerance if one disk fails. Capacity equals the capacity of the smallest disk.
  • RAID 5 (striping with parity): Minimum three disks. Fault tolerance if one disk fails, good balance between performance and capacity.
  • RAID 6 (striping with dual parity): Minimum four disks. Fault tolerance if two disks fail. Higher reliability, but slightly lower performance than RAID 5.
  • RAID 10 (mirroring and striping): Minimum four disks. Excellent performance and high fault tolerance (can withstand multiple disk failures if they are not in the same mirrored pair).

For Nextcloud on a dedicated server, a common combination is NVMe for OS, database, and cache, and a RAID 10 of SATA SSDs or HDDs for primary file storage. You can read more about disk selection here: NVMe vs SSD vs HDD: which disk to choose for a server.

Performance and Scaling: How Many Users Can Your Own Nextcloud Handle?

The answer to "how many users can your own Nextcloud handle" depends on their work intensity, data volume, and, of course, the server's hardware characteristics. Here are approximate recommendations:

• Up to 10 users (light usage):
  • CPU: 2-4 cores (e.g., Intel Xeon E3/E5 or AMD Ryzen).
  • RAM: 8-16 GB.
  • Disk: 500 GB NVMe/SSD (for performance) or 2x2TB HDD in RAID 1 (for capacity).
  • Network: 100 Mbps.
• 20-50 users (moderate usage, synchronization, collaboration):
  • CPU: 4-8 cores (Intel Xeon E3/E5, AMD EPYC).
  • RAM: 16-32 GB.
  • Disk: 1 TB NVMe for OS/DB/cache and 4x2TB SATA SSD in RAID 10 for files (or 4x4TB HDD in RAID 10).
  • Network: 1 Gbps.
• 50-100+ users (intensive usage, OnlyOffice/Collabora):
  • CPU: 8-16+ cores (Intel Xeon E5/E7, AMD EPYC).
  • RAM: 32-64+ GB.
  • Disk: 2 TB+ NVMe in RAID 1 for OS/DB/cache and 6x4TB+ SATA SSD in RAID 10 for files.
  • Network: 1-10 Gbps.

For Nextcloud performance optimization, the following are also important:

• Database: MariaDB or PostgreSQL. Always use SSD/NVMe for the database.
• Caching: Redis for Transactional File Locking and APCu for PHP cache.
• Web Server: Nginx with PHP-FPM is usually more performant than Apache for Nextcloud.

# Example PHP-FPM configuration for Nextcloud (php.ini)
opcache.enable=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

apc.enable_cli=1
apc.shm_size=128M
apc.ttl=7200
apc.entries_hint=4096

memory_limit = 512M # Or more, depending on the load

Integration with OnlyOffice and Collabora: In-Browser Office for Your Cloud

One of the key features of a modern own cloud server is the ability to edit documents directly in the browser. Nextcloud integrates excellently with OnlyOffice and Collabora Online (based on LibreOffice). However, these office suites are quite resource-intensive.

• Resource Requirements: Each open document, especially during collaborative editing, consumes significant amounts of RAM and CPU on the OnlyOffice/Collabora Document Server.
• Deployment: For small installations (up to 20-30 users), OnlyOffice/Collabora can be installed on the same Nextcloud dedicated server. However, for larger teams, it's recommended to allocate a separate VPS for the Document Server or use Docker containers on the same dedicated server to isolate resources.
• Licensing: Collabora Online Development Edition (CODE) and OnlyOffice Community Edition are free but have limitations on the number of concurrent connections or features. Commercial versions offer extended capabilities and support.

# Example of running OnlyOffice Document Server via Docker
docker run -i -t -d --restart=always \
    -p 8000:80 \
    -e JWT_SECRET=your_jwt_secret \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data \
    onlyoffice/documentserver

Using Docker for services like OnlyOffice/Collabora allows for efficient resource management and simplifies deployment. You can learn how to use a dedicated server for Docker here: Dedicated Server for Docker: bare metal for containers.

Backups and Security: The Cornerstone of Your Self-Hosted Cloud

The reliability of a self-hosted cloud directly depends on its backup strategy and overall security. With a Nextcloud dedicated server, you have full control over these aspects.

• Backup Strategy:
  • Daily incremental backups: For Nextcloud files.
  • Daily full backups: For the Nextcloud database.
  • Weekly full backups: Of the entire server or critical directories.
  • Off-site storage: It's important to store backup copies on another server or in cloud storage to protect against complete data center failure.
• Encryption: Always use encryption for data on disk (Full Disk Encryption, FDE) and for data in transit (HTTPS with Let's Encrypt).
• Server Security:
  • Regular OS and Nextcloud updates.
  • Firewall configuration (UFW, firewalld) to restrict access only to necessary ports.
  • Using Fail2Ban to protect against brute-force attacks.
  • Strong passwords and two-factor authentication (2FA) for administrative accounts.

# Example command for backing up Nextcloud files using rsync
# Replace /path/to/nextcloud/data and /path/to/backup/destination
rsync -Aax --delete /path/to/nextcloud/data/ /path/to/backup/destination/nextcloud_data_backup/

# Example command for backing up a MariaDB database
# Replace nextcloud_db_user, nextcloud_db_name, and /path/to/backup/destination
mysqldump -u nextcloud_db_user -p nextcloud_db_name > /path/to/backup/destination/nextcloud_db_backup_$(date +%F).sql
