Nextcloud je self-hosted file sync, dijeljenje, kalendar, kontakti, video calls — open-source alternativa Google Workspace-u i Microsoft 365. Idealan za EU kompanije koje žele full data residency i ne predavat podatke US-cloud-ovima. Ovo je vodič za Nextcloud hosting u 2026.
Nextcloud ukratko
- Open-source PHP app za file sync + collaboration, AGPL licenca.
- Verzije: Nextcloud Hub 9 (current, Q1 2026).
- Apps: Files, Talk (video conferencing), Mail, Calendar, Contacts, Notes, Office (Collabora ili OnlyOffice integration).
- Desktop clients (Win/Mac/Linux), mobile apps (iOS/Android).
- Federation između instanci.
Zašto self-host Nextcloud
- EU data residency (GDPR comfort).
- Bez per-user subscription cost (jednom platiš server).
- Full kontrola nad backup, encryption, access policy.
- Integracija s vlastitim alatima (LDAP, AD, custom SAML SSO).
- End-to-end encryption za sensitive fajlove.
Tehnički zahtjevi Nextcloud Hub 9
- PHP 8.1+ (8.3 preporučljivo)
- MariaDB 10.6+ ili PostgreSQL 13+ (Postgres preferiran za veće instalacije)
- Redis za session + memory cache
- nginx ili Apache
- SSL obavezan
- Storage: ovisi o veličini tima i broju fajlova
Sizing
| Tim | vCPU | RAM | Storage | EUR/mj |
|---|---|---|---|---|
| Mali (do 10 korisnika) | 2 | 4 GB | 200 GB | ~30-50 |
| Mid (do 50 korisnika) | 4 | 8 GB | 1 TB | ~70-150 |
| Veliki (do 500 korisnika) | 8+ | 16-32 GB | 5+ TB | ~200-500 |
| Enterprise | 16+ | 64+ GB | 20+ TB | 500+ |
Performance optimization
- APCu za local cache.
- Redis za distributed cache + file locking (kritično).
- PHP-FPM tune-iran (pm.max_children podizgnut).
- OPcache sa preload (Nextcloud ima vodič).
- Background jobs preko cron umjesto AJAX (puno brže).
- Object storage (S3 ili Swift) za userdata umjesto file system na velikim instalacijama.

Backup
Nextcloud data ima 3 dijela:
data/directory — user uploads.config/config.php— config.- Database (MariaDB/Postgres dump).
Sve tri backup-at off-site (S3, B2, drugi server). Test restore mjesečno.
WMD i Nextcloud hosting
WMD postavlja Nextcloud Hub 9 na dedicated VPS — PHP 8.3, Postgres (preporučljiv) ili MariaDB, Redis za cache + locking, OnlyOffice ili Collabora za office editing, Talk za video calls. SSL Let's Encrypt, JetBackup daily za data + database + config, off-site sync na drugi VPS. LDAP/AD integration ili SAML SSO setup za enterprise. Mjesečni Nextcloud upgrade kroz Maintenance Plan.
Paketi:
- NC Tim (10 korisnika, 200 GB): 2 vCPU, 4 GB RAM — od ~40 EUR/mj.
- NC Pro (50 korisnika, 1 TB): 4 vCPU, 8 GB RAM — od ~110 EUR/mj.
- NC Business (500 korisnika, 5+ TB): 8+ vCPU, 16-32 GB RAM — od ~280 EUR/mj.
FAQ
Nextcloud vs Google Drive trošak? Google Workspace ~6-18 USD/user/mj. Nextcloud ~110 EUR/mj za 50 korisnika = 2.2 EUR/user. Ušteda za team 10+ je drastična.
Mogu li Nextcloud na shared hostingu? Tehnički da za mali tim. Praktički — Redis, cron, performance — VPS je realniji.
End-to-end encryption? App postoji ali ima caveats (ne radi za sharing, neke apps inkompatibilne). Server-side encryption pomaže ali ima ključ.
Nextcloud Office (Collabora) vs OnlyOffice? OnlyOffice ima bolji MS Office compatibility. Collabora je više Linux-friendly.
Trebaš Nextcloud setup za tim ili kompaniju? WMD postavlja full Nextcloud stack + LDAP/SSO + backup. Javi se preko kontakt forme.
