Self-Hosting & Data Sovereignty
Take back control of your IT.
Self-hosted services instead of third-party systems: GDPR-compliant, cost-efficient and independent of tech giants – operated where you keep control.
Why self-hosting
Five commitments that make the difference.
-
Privacy by design: data protection is part of the architecture, not a setting added later.
-
Self-hosted solutions for genuine data sovereignty.
-
A complete IoT stack from LoRaWAN sensors to cloud APIs.
-
Automation first – with infrastructure as code and CI/CD.
-
Based in Germany: Chemnitz, Leipzig and Dresden, remote across the country.
Starting point and result
From third-party systems to your own IT.
Cloud services are convenient. The question is who owns the data they produce.
Without self-hosting
A typical starting point in IT landscapes that have grown over time:
-
Data held by third parties
Mail, files and customer data sit with providers whose server location and further processing you do not control.
-
Dependencies
Prices, features and notice periods change without your involvement; leaving is expensive.
-
Opaque access
Who reads, processes or passes on data often cannot be traced in detail.
With self-hosting
Services on your own or dedicated infrastructure – with clear responsibility:
-
Data control
Your data sits where you decide – on servers in your own building or in an environment of your choice.
-
Predictable cost
Recurring subscription fees become operating and hardware costs that you control yourself.
-
Traceability
Access, backups and updates follow your rules and are documented.
If self-hosting is too much for you, TNI also runs and maintains your infrastructure for you. Talk to us
What changes
Control, cost, compliance.
Self-hosted services change three things at once.
-
Control
You decide which services run, where the data sits and who can access it.
-
Cost
Recurring subscriptions become predictable operating costs without a cloud markup.
-
Compliance
Data held in Germany, GDPR-compliant processing and traceable access.
Scope
What we run for you.
We build and operate the services that otherwise run as third-party systems – individually or as a bundle.
-
Servers & virtualisation
Building and operating servers and virtualisation platforms, among others based on Proxmox.
-
Network & firewall
Network, VLANs and firewall, among others with OPNsense and TP-Link components.
-
Data & files
File storage, backups and databases in your own building instead of someone else's.
-
Business applications
ERP and line-of-business applications, among others based on Odoo.
-
Monitoring & operations
Monitoring, updates and backup jobs, so that operations do not become a permanent chore.
-
IoT to cloud API
LoRaWAN sensors, radio network and dashboards through to the connected cloud API.
Our partners
Technologies from our partners carry the infrastructure we build and operate.
How we work
Five steps to your own infrastructure.
We migrate service by service – with a clear way back and without interrupting live operations.
-
01
Inventory
Which services run where, what data is produced and which dependencies exist.
-
02
Selection
We prioritise by benefit, effort and risk and propose which services are worth doing first.
-
03
Pilot
One service is self-hosted and tested in parallel operation, without interrupting live operations.
-
04
Migration
Moving data and access with a clear way back; backup and contingency plan included.
-
05
Operations
Updates, monitoring and backups run as recurring operations – automated wherever possible.
Honestly
What self-hosting costs.
Self-hosting is not a free ride. These points are part of the honest picture.
-
Operating effort
Servers need updates, backups and monitoring. We take that on – or hand it over to your team, documented.
-
Lead time
Migration and testing take time; a service rarely runs fully in-house from one day to the next.
-
Hardware or a dedicated environment
It does not work entirely without infrastructure. Depending on the goal a dedicated machine is enough, or you need a server on site.
-
Not every service is worth it
Some tools make more sense as a third-party system. We will say so if self-hosting offers you no advantage.
Fit
Who it suits – and who it does not.
A good fit if …
- You process personal or confidential data and want to control where it is held.
- You want predictable costs instead of growing subscriptions.
- You want to stay independent of individual providers in the long run.
- You operate or want to build your own or dedicated infrastructure.
Less of a fit if …
- You want to operate as little of your own infrastructure as possible.
- Your requirements are fully covered by a single standard service.
- You need a solution for just a few weeks at short notice.
Common questions
Answered briefly.
Is TNI's self-hosting GDPR-compliant?
We design the services so that processing meets GDPR requirements and keep data largely in Germany. That does not replace a legal assessment of your individual case.
Do we need our own servers for this?
Not necessarily. Depending on the service, a dedicated machine or a virtual environment is enough; for larger scenarios a server on site is worth it.
Which technologies does TNI use?
Among others Odoo, Proxmox, OPNsense and TP-Link components – all partners we work with. Their products carry the infrastructure we build and operate for our clients.
What happens if a service fails?
Backups, monitoring and a documented contingency plan are part of operations; for critical services we plan recovery in advance.
Do you also take on ongoing operations?
Yes. We operate the services fully or hand them over to your team, documented – depending on how much control you want to take on yourself.
