NextCloud / OwnCloud Self-Hosted File Sharing Servers

NextCloud and OwnCloud are the leading self-hosted alternatives to Dropbox, Box, and Google Drive — file sync/share, online office documents, calendar, contacts, video calls, all running on your own server. We stock hardware sized for everything from 5-user SMB deployments to 5,000-user enterprise.

Hardware sizing: per-user storage is typically 50-200 GB (so 50 users = 2.5-10 TB allocation). Memory needs are modest: 8 GB for <100 users, 32 GB for 500 users, 64 GB for 1,000+ users. Database (PostgreSQL or MariaDB) and Redis for caching are the main scaling factors.

Recommended platforms: Dell PowerEdge R650 (1U, 32 cores, 128 GB RAM) + Dell PowerEdge R740xd2 (24-bay storage tier) — total cost $5-8K refurbished for a 500-user deployment. For SMB / homelab (1-50 users), a single R650 with 32 GB RAM and 2 TB local SSD is enough.

Compliance angle: many EU customers, healthcare providers, and government agencies cannot use US cloud (Google Workspace, Microsoft 365) due to GDPR / HIPAA / sovereignty concerns. NextCloud on local hardware solves this — full data residency, encryption at rest, optional federation between sites.

Frequently Asked Questions

Is NextCloud free?

Yes — NextCloud Server is open source (AGPL licence), free for unlimited users. Paid Enterprise subscription ($36-90 per user per year) adds professional support, hot-patches, and enterprise-only features (audit logging, advanced antivirus, SAP integration). Most SMB and homelab deployments use the free Community edition.

How much storage do I need for NextCloud?

Plan 50-200 GB per user based on usage profile. Knowledge worker / office user: 50-100 GB. Engineer / designer (large files): 200-500 GB. Photographer / videographer: 1-5 TB. Total = users × per-user × 1.5 safety margin. A 100-user company typically needs 10-20 TB.

Can I integrate NextCloud with Active Directory?

Yes — NextCloud has built-in LDAP / Active Directory user-sync. Users authenticate against your existing AD, with permissions mapped by AD group membership. SSO via SAML 2.0 also works (Microsoft ADFS, Okta, Auth0).

Is NextCloud secure?

Yes — NextCloud has been independently audited (SAP, German BSI), supports end-to-end encryption (E2EE) for sensitive folders, hardware token (FIDO2 / YubiKey) authentication, and granular sharing controls. Used by major government agencies including the German Federal Government and the EU Commission.
