Linux Server Administration

Servers that just run — no maintenance windows at inconvenient hours, no late-night pager calls. We operate, harden, and optimize your infrastructure so you can focus on your business.

What We Do

Server Setup & Migration

From first boot to production

Fresh installations, migration of existing systems, or hardware transitions. Cleanly documented, with a rollback plan and zero data loss.

Operations & Maintenance

Running 24/7 without you noticing

Kernel and package updates, service monitoring, log analysis, performance tuning. We take care of your servers — so you don't have to.

Security Hardening

Minimize your attack surface

SSH keys instead of passwords, fail2ban, firewall rules, AppArmor/SELinux profiles, automated security updates, and regular audits.

Distributions & Server Software

Linux Distributions

What we work with every day

  • Debian & Ubuntu LTS
  • Rocky Linux & AlmaLinux
  • RHEL & CentOS Stream
  • Alpine Linux (Container)
  • openSUSE

Web & Database

What your application needs

  • nginx, Apache, Caddy
  • MariaDB, MySQL, PostgreSQL
  • Redis, Memcached
  • RabbitMQ, NATS
  • OpenSearch & Elasticsearch

Mail & DNS

Own infrastructure instead of third-party providers

  • Postfix & Dovecot with DKIM/SPF/DMARC
  • Bind9, Knot DNS, PowerDNS
  • Rspamd, ClamAV
  • OpenVPN & WireGuard
  • HAProxy & nginx as Reverse Proxy

Scripting, Automation & CI/CD

Shell & Scripting

Automate the repetitive away

  • Bash & POSIX Shell
  • Python for complex tasks
  • cron, systemd-timer, at
  • Ansible for multi-host management
  • Idempotent, tested scripts

Containers & Orchestration

Reproducible environments

  • Docker & Docker Compose
  • Podman
  • Kubernetes (k3s, k8s)
  • Build & sign container images
  • Image registry setup

CI/CD & Deployment

From commit to live server

  • GitLab CI & GitHub Actions
  • Self-hosted runners
  • Zero-downtime deployments
  • Blue-green & canary releases
  • Rollback strategies

Focus Areas

Monitoring & Alerting

Prometheus, Grafana, Loki, and Uptime-Kuma. We measure what truly matters — and alert only when something is actually on fire, not on every blip.

Backup & Disaster Recovery

BorgBackup, restic, or ZFS snapshots. Off-site, encrypted, regularly tested. A backup that has never been restored is not a backup.

Storage & Filesystems

ZFS, btrfs, ext4, LVM. We choose the right filesystem for the use case and configure snapshots, quotas, and replication.

Performance Tuning

Kernel parameters, sysctl, I/O scheduler, database indexes, nginx tuning. We turn 2-second response times into 200 milliseconds.

Directly with the Admin

No helpdesk, no first-contact tier-1, no escalation through five layers. You speak immediately with the person who actually manages the server.
