Sysadmin services

Stable, automated infrastructure — no surprises

Linux operations, CI/CD and infrastructure as code from a team that prevents incidents instead of chasing them.

Why us?

Prevention instead of firefighting

A good sysadmin's work shows in the calm, not in the number of interventions.

  • Proactive monitoring

    Monitoring and capacity planning so problems surface before your users notice them.

  • Every step documented

    Infrastructure lives in code and interventions are logged — no tribal knowledge.

  • Fast incident response

    A committed response time and root-cause analysis so the same fault doesn't return.

  • Security by default

    Server hardening, access control and a patching cadence to shrink the attack surface.

What we do

Full-scope operations and automation

From server tuning to incident response.

  • Linux server operations

    Provisioning, tuning and maintenance on Debian/Ubuntu and RHEL-based systems.

  • Server hardening

    A security baseline, firewall, SSH rules and access control put in place.

  • CI/CD pipelines

    Automated build, test and deploy on GitHub Actions or GitLab CI.

  • Infrastructure as code

    Reproducible environments with Ansible and Terraform, kept under version control.

  • Monitoring and log analysis

    Metrics and log collection, dashboards and alerts on the real state.

  • Incident response

    On-call response, root-cause analysis and a written post-mortem.

How we start

From chaos to predictable operations

Five steps from assessment to continuous monitoring.

  1. Infrastructure audit

    We assess existing servers, the risks and the missing automation.

  2. Stabilisation

    Fixing the most pressing security and reliability gaps by priority.

  3. Automation

    Putting infrastructure into code and introducing CI/CD and backup pipelines.

  4. Monitoring rollout

    Setting up metrics, logs and alerts so the system speaks for itself.

  5. Continuous oversight

    Regular maintenance, capacity planning and a monthly status report.

Engagement models

How do we bill?

The size of your systems and the response time you need set the budget.

  • A monthly retainer for predictable oversight and maintenance.
  • A one-off project price for an audit, stabilisation or automation work.
  • An on-call option for critical systems with a committed response time.

We recommend the right model based on the results of the infrastructure audit.

FAQ

Common questions about operations

Worth clarifying before we work together.

Do you only operate your own servers?
No, we take over your own or cloud infrastructure too — first we assess the state and risks with an audit.
What does infrastructure as code mean in practice?
The environment is described in version-controlled code (Ansible, Terraform), so it's reproducible, auditable and not dependent on one person's knowledge.
Is there on-call cover for nights and weekends?
Yes, an optional on-call package for critical systems with a contractually defined response time.
How do you handle security updates?
We work to a scheduled patching cadence and validate risky updates in a staging environment first.
Do we get a report on the work done?
We provide a monthly report on availability, incidents and the maintenance carried out.
