Ollama is the inference layer for local language models. Instead of sending company data to external AI services, models such as Llama, Mistral, Gemma or Qwen run on your own infrastructure.
We operate Ollama for production use: with GPU tuning, model management, API gateways, monitoring, backup strategy and clean integration into Open WebUI, AnythingLLM, RAG pipelines and internal applications.
Ollama is easy to start, but production operations need more than a Docker container. We plan hardware, model sizes, VRAM budget, access paths, updates and observability around your use case.
The software is licensed under MIT. That makes Ollama a strong open foundation for sovereign AI infrastructure, provided security, operations and model governance are handled properly.
Models run on your own hardware, in your own data center or in a European cloud. Data stays inside your controlled environment.
We size VRAM, CPU, RAM and storage around model size, context window, user count and response-time requirements.
Clean handling of model versions, pull processes, approvals and rollbacks for reproducible AI environments.
On-premise, AI Cube, GPU server or private cloud: Ollama is operated so data protection, availability and access control fit together.
We connect Ollama to Open WebUI, AnythingLLM, LiteLLM, internal applications, automations and RAG pipelines.
Monitoring, updates, backups, model tests, security hardening and support turn a local demo into a reliable AI platform.
Ollama handles local model execution and forms the technical base for chat, RAG, agents and internal AI APIs.
We handle model changes, updates, GPU utilization, health checks and clear processes for production environments.
Access through VPN, SSO, internal networks or API gateways. Sensitive data remains inside controlled infrastructure.
Open source enterprise-ready for productive workloads - we run your applications with highest security standards and enterprise support

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands.
