Decades of Linux & UNIX operations and support

Linux & UNIX Support and System Administration

Linux & UNIX Support and System Administration

Devanux provides end-to-end Linux and UNIX expertise for stable, secure, and scalable operations. We work with Red Hat Enterprise Linux, Debian/Ubuntu, SUSE, and IBM AIX across on-prem, cloud, and hybrid environments. Our services cover installation, hardening, troubleshooting, performance tuning, high availability, backup/DR, and day-to-day operations.

Security and compliance are built in. We manage patching and vulnerability remediation, implement least-privilege access, and align operations with standards such as NIS2, ISO 27001, and NIST. We automate with Ansible and Infrastructure as Code to make environments reproducible and easy to maintain.

For observability, we deploy and run Prometheus and Grafana with actionable alerting, so issues are detected early and resolved fast. Whether you need to modernise legacy UNIX, run mission-critical Linux at scale, or migrate workloads to cloud, we make your platform reliable and future-ready.

Experience across regulated and mission-critical environments

We have operated Linux and UNIX in sectors with strict uptime, audit, and security requirements — including finance, manufacturing, media, and public sector.

High-availability Linux at scale
Design and operations for HA clusters (e.g., Pacemaker/Corosync) and resilient load-balanced services on-prem and in the cloud.
AIX & UNIX to modern Linux
Planning and executing low-downtime migrations and consolidation from legacy UNIX (incl. IBM AIX) to Linux.
Compliance & hardening
Security baselines, CIS-aligned hardening, access control and audit trails mapped to NIS2/ISO 27001/NIST practices.
Observability & automation
Monitoring with Prometheus/Grafana, alerting, Ansible playbooks, and maintenance windows for predictable operations.
