// the operational reality

Delivering Nextcloud at scale is operationally complex. NexTerminal removes that complexity.

Manually provisioning, isolating, updating, and backing up Nextcloud instances for every customer is slow, error-prone and impossible to scale. NexTerminal automates the entire lifecycle — provisioning, scaling, updates, backups, restore — and gives you and your resellers an API-driven platform you run under your own brand.

  • Hours of manual setup → minutes of automated rollout
  • Shared servers → strict per-tenant VXLAN isolation
  • Risky updates → mandatory pre-update backups
  • Vendor lock-in → your hardware, your margin
// why NexTerminal

Become the Nextcloud cloud provider — on your terms.

Six reasons CTOs, product leads and ops teams at hosters pick NexTerminal over building it themselves.

Sell Nextcloud at scale

Turn your Proxmox cluster into a Nextcloud-as-a-Service platform. White-label, multi-tier reseller, full margin.

From hours to minutes

Fully automated provisioning. A new customer cloud goes live in minutes — by click or API — with rollback on failure.

True tenant isolation

Every tenant gets its own VXLAN/SDN network, dedicated VMs, S3 bucket and database. Strict firewall denies between tenants.

API-first & white-label

Drive the entire platform from your existing customer portal or billing system. Scoped tokens, OpenAPI, server-to-server flows.

Data sovereignty & GDPR

Data stays on your hardware in the EU. No hyperscaler. No third-country transfer. Full audit log per action.

Predictable operations

Stepwise major updates with mandatory pre-update backups, HA load balancing, monitoring and diagnostics built-in.

// platform capabilities

Everything you need to run Nextcloud as a service

A complete, opinionated platform — built specifically for multi-tenant Nextcloud hosting at scale.

Multi-Tenant Provisioning

New cloud per click or API: tenant network, VMs, DB, S3, domain, TLS, LB route, health check — all automated.

VXLAN / SDN Isolation

Per-tenant Layer-2 VXLAN network on Proxmox SDN. Strict firewall DENY between tenants. Up to tens of thousands per cluster.

Reseller Hierarchy

Platform → Resellers → End customers. Quotas, entitlements and scoped tokens at every level. Full white-label.

REST API (v1 + Admin)

Fine-grained scopes (clouds:read, clouds:create, domains:manage…), server-to-server tokens, OpenAPI / Swagger out of the box.

Multi-VM Scaling

Split web and worker VMs, autoscale web nodes, shared NAS for consistency, dedicated Redis pools.

S3 Object Storage

Per-tenant Garage / MinIO bucket. Live quota grow & shrink with safety guard against shrinking below used storage.

Domains & Automatic TLS

Add and verify custom customer domains, set primary, automatic Let's Encrypt via Caddy On-Demand TLS, emergency fallback.

Collaboration Add-ons

One-click Collabora Online, Nextcloud Talk + High-Performance Backend + TURN, Whiteboard, Notify-Push — provisioned via job queue.

Safe Stepwise Updates

Major-by-major Nextcloud upgrades with a mandatory pre-update backup. If backup fails, update is aborted, cloud untouched.

Backup & Restore

DB dump + NAS archive (config, apps, themes). Retention, manual restore via UI/API, import of existing backups for migration.

HA Load Balancing

Caddy-based LB with VRRP floating IP. Safe LB rebuilds. WebSocket / Talk connections survive config reloads.

Custom App Registry

Central registry to roll out your own Nextcloud apps to one cloud, one reseller or globally — fully automated.

Optional AI Layer

Per-tenant key issuance via LiteLLM gateway → power Nextcloud Assistant / AI features for your end customers.

Lifecycle Controls

Suspend / unsuspend (traffic only, VMs stay), maintenance mode, branded "cloud being created" splash pages.

Realtime Dashboard

Live overview, jobs, metrics, audit log of every action, diagnostics tools, topology and IP-map views.

Infrastructure Mgmt

IP pools, SDN zones, service VMs, VM templates and cluster nodes — all from one operator UI.

// inside the platform

A control plane built for serious operators

Every action — from provisioning a tenant to attaching Talk HPB or reviewing the audit log — lives in one consistent operator UI. Below: a realistic look at three core views.

// how it works

From Proxmox cluster to Nextcloud cloud provider in four steps

01

Install

NexTerminal deploys as the control plane on your own Proxmox cluster. No hyperscaler dependency.

02

Create resellers & plans

Set up tenants, quotas and API access — through the UI, or programmatically from your existing customer portal.

03

Provision clouds

Click or API call → a fully isolated Nextcloud instance with storage, domain, TLS and add-ons spins up automatically.

04

Operate & scale

Update, back up, scale, suspend and bill — automated, monitored, with a full audit trail.

// for whom

Built for the teams that run hosting platforms

/ persona 01

Hosting CTO / Platform Architect

Decides the platform technology

Proxmox-native, real VXLAN/SDN tenant isolation, HA LB, scales to thousands of tenants, full data sovereignty.

/ persona 02

Product / GM at the MSP

Opens a new revenue stream

Time-to-market in days, white-label, multi-tier reseller model, predictable margin, no vendor lock-in.

/ persona 03
