From practice: platforms, automation and software
An overview of the topics we work on every day. The screenshots come from real environments – names, addresses and customer data have been anonymised.
- 30+Linux systems under monitoring
- 3Proxmox nodes in the cluster
- 90 daysof metrics and logs retained
- 30 yearsof IT experience
Container platforms in your own data centre
We plan and run virtualisation and container platforms that don’t depend on hyperscalers – from a compact Proxmox cluster to OpenShift and Kubernetes.
- High availability with automatic failover and failback
- ZFS replication between nodes, without shared storage
- Unprivileged LXC with Podman as a lean standard for services
- Migrating existing systems with seconds rather than hours of downtime
Patch management for dozens of Linux servers
Rolling out updates without losing sleep: inventory straight from the virtualisation layer, playbooks with built-in safety nets and a UI where routine work runs with a single click.
- Inventory generated automatically from the Proxmox API
- Snapshot before every release upgrade
- Post-patch checks: are all containers running, are all ports reachable?
- Target validation in every playbook against “success without effect”
Monitoring that warns you in time
A central monitoring stack collects metrics and logs from all systems, shows pending updates and bottlenecks at a glance and reports problems where they won’t be missed.
- Pending updates, reboots and vulnerabilities per server
- Router logs, internet quality and website availability
- Certificate and outage alerts
- Alerts via WhatsApp to the responsible group
Connecting sites securely
From the small office to the remote site: we segment networks cleanly, connect sites via VPN and make Wi-Fi measurable too.
- VLANs and firewall rules on a “only what’s needed” basis
- WireGuard tunnels between sites and for remote access
- Wi-Fi monitoring for lab and school networks
- Containers directly on the router where it makes sense
Custom software and AI-assisted development
When off-the-shelf software doesn’t fit, we build lean applications – fast with AI assistance, production-ready from day one with CI/CD and containers.
- Web applications for schools and administration
- Interfaces and gateways, e.g. for notifications
- Automatic deployment on every push
- Development with AI assistants, responsibility with people
Controlling building systems remotely
Home Assistant as the central control for several sites – with voice control, automations and monitoring, even for houses where nobody is on site.
- Air conditioners and sensors from different vendors in one interface
- Matter devices at a remote site via a VPN tunnel
- Voice control via a custom Alexa skill
- Humidity and dew-point control against mould
