Infrastructure & Operations

DevOps & System Administration

Linux servers, pipelines, monitoring and security hardening, handled by engineers who also write the software. We keep systems patched, observable and uneventful in the best possible way.

01 · Overview

Operations that prevent incidents instead of reacting to them

Reliable systems come from routine: patched servers, automated deployments, logs you can search and alerts that mean something. We bring that routine to your infrastructure, whether it is a handful of Linux servers or a container platform.

We start by documenting what exists, then improve incrementally: configuration management with Ansible, pipelines in GitHub Actions or GitLab CI, metrics with Prometheus and Grafana, centralised logs and a hardening baseline. No big-bang rewrites.

02 · Capabilities

What we deliver

Day-to-day operations and the automation that makes them predictable.

Linux administration

Server provisioning, user and package management, storage, networking and routine maintenance.

Deployment workflows

Pipelines that test, build and release consistently, with approvals and rollback built in.

Service management

systemd units, process supervision, log rotation, resource limits and scheduled jobs configured properly.

Monitoring and logging

Metrics, centralised logs and alerts on user-facing symptoms, with dashboards your team will actually use.

Security hardening

SSH keys only, firewalls, automatic security updates, least-privilege service accounts and audit trails.

Automation and maintenance

Ansible playbooks, patch management, dependency and OS upgrades and capacity planning.

03 · Approach

From firefighting to calm operations

An incremental framework that improves speed, safety and visibility without disrupting your team.

  1. 01

    Assessment and roadmap

    We audit and document the current setup and agree priorities.

    • Current state audit
    • Tooling gaps
    • Risk review
    • 90-day roadmap
  2. 02

    Automation and pipelines

    Manual steps are replaced with code, one area at a time.

    • CI/CD setup
    • Infrastructure as code
    • Configuration management
    • Secret rotation
  3. 03

    Observability and alerting

    Metrics, logs and alerts that surface problems before users notice.

    • Metrics collection
    • Log aggregation
    • Alert rules
    • On-call runbooks
  4. 04

    Support and evolution

    Ongoing care, reviews and training under an agreed support plan.

    • Incident response
    • Monthly health checks
    • Patch management
    • Team training

04 · Technical considerations

The details that decide success

Operations quality comes from habits. These are the ones we build in.

Automate the second time
A manual task done once is documented; done twice, it is scripted. Over time the runbook becomes code.
Alert on symptoms
Alerts fire on user-facing symptoms such as error rates and latency, each with a runbook, to avoid alert fatigue.
Rebuild rather than patch by hand
Where practical, servers are rebuilt from configuration instead of edited manually, keeping environments consistent.
A defined patch cadence
Security updates are applied on a schedule, urgent fixes are handled out of cycle and every change is recorded.
Backups and restore drills
Backups are monitored and restores are rehearsed, so recovery time is known before it is needed.
Access hygiene
Individual accounts, key rotation and prompt removal of access when people leave or roles change.

05 · Outcomes

What you can expect

  • Faster, safer releases
  • Fewer incidents and quicker recovery
  • Hardened, documented servers
  • An operations setup your team understands

06 · FAQ

DevOps & System Administration: common questions

Ask us something else
Do you manage on-premises servers as well as cloud?

Yes. We manage physical, virtual and cloud Linux servers, using Ansible for configuration and consistent monitoring across environments. We can also help plan a move to the cloud when it makes sense.

How quickly can code reach production?

With an automated pipeline, a merged change typically reaches production in minutes once tests, security checks and builds pass. The exact time depends on your test suite and approval steps.

What does your monitoring cover?

Server health such as CPU, memory, disk and network; application metrics such as response times and error rates; centralised logs; and alerts routed to the right people with clear runbooks.

Do you offer out-of-hours support?

Yes, under a support plan. We agree coverage hours, response times and escalation paths with you, and significant incidents receive a written review with follow-up actions.

Can you take over an existing, messy setup?

Yes. We audit and document the current state first, then introduce automation, monitoring and clean-up in small, low-risk steps rather than a disruptive rebuild.
