Enterprise-Grade Linux Infrastructure for Christchurch & Canterbury
From file servers to container platforms, we architect open-source infrastructure that cuts costs by 40-60%, eliminates vendor lock-in, and integrates seamlessly with your Apple and Windows environments.
magnumit builds secure, stable Linux infrastructure for Christchurch and Canterbury organisations that need full control, predictable costs, and long-term reliability. We design file services, identity platforms, Proxmox virtualisation, container clusters, and network services using proven open-source technologies — delivering enterprise-grade performance without Windows Server licensing overhead.
Every solution is built for mixed environments. Apple devices, Windows endpoints, and cloud applications authenticate and interoperate using open standards such as SMB, NFS, LDAP, SAML, and OAuth. You gain Active Directory–level capability — single sign-on, policy enforcement, audited access — without domain controllers or CALs.
With over 20 years of Linux administration and automation experience, we work on-site across Christchurch and remotely throughout New Zealand. From resilient file servers to multi-site Proxmox clusters, we deliver fully documented builds, clear operating procedures, and long-term support your team can rely on.

Frequently Asked Questions
Common questions about Linux infrastructure consulting in Christchurch
Why choose Linux infrastructure instead of Windows Server?
Lower total cost of ownership (40-60% savings over 5 years), no Client Access License fees, no forced upgrade cycles, better security posture with community-driven patches, longer hardware lifecycle, and full control over updates and configuration. For file services, identity, and infrastructure roles, Linux delivers enterprise-grade reliability without licensing complexity.
Can Linux file servers work with Windows and Mac clients?
Absolutely. We configure Samba (SMB) for Windows-compatible file sharing, AFP for legacy Mac support, and NFS for Unix/Linux clients. Permissions, Access Control Lists (ACLs), and integration with cloud identity platforms (JumpCloud, Microsoft Entra ID) or Active Directory work seamlessly. Most clients never know they're connecting to Linux.
Which Linux distributions do you support?
We primarily deploy Ubuntu LTS (Long Term Support) for general infrastructure, Rocky Linux or RHEL for environments requiring vendor support contracts, and Debian for lightweight services. Distribution choice depends on your compliance requirements, internal expertise, and application compatibility. All receive 5+ years of security updates.
How do you handle security patching and updates?
Automated patch management with Ansible playbooks, tested in staging before production deployment. Critical security updates applied within 24-48 hours. Regular OS updates on monthly maintenance windows. All changes documented, logged, and reversible. Prometheus monitoring alerts on available updates and security advisories.
What's the total cost of ownership compared to Windows Server?
40-60% lower over 5 years for typical file, identity, and infrastructure workloads. Savings come from: no Windows Server licensing or CALs, no System Center Configuration Manager (SCCM), longer hardware lifecycle (7+ years vs 5), lower support overhead with automated patching, and no forced migration costs. We provide detailed TCO analysis during discovery.
Do you support existing Linux systems or only new deployments?
Both. We assess, document, and stabilise existing Linux infrastructure—even systems deployed by others or inherited through acquisition. Common engagements include security hardening legacy deployments, automating manual processes with Ansible, modernising end-of-life systems, and implementing monitoring for unmanaged infrastructure.
Can you integrate Linux infrastructure with our Active Directory?
Yes. Integration options include: direct AD authentication using SSSD or Winbind, hybrid identity synchronisation with cloud directories (JumpCloud, Entra ID), or deploying open-source alternatives (FreeIPA, Keycloak) that federate with AD. Approach depends on your security model, compliance requirements, and whether you're planning to migrate away from Windows domain controllers.
What does ongoing support look like for Linux infrastructure?
Retainer-based monitoring, patching, and maintenance from $2,500/month. Includes 24/7 uptime monitoring with Prometheus, automated security patching, incident response, capacity planning, and quarterly security reviews. Alternatively, we can train your internal team and hand off fully documented, automated systems with runbooks for independent operation.
Do you provide on-site consulting in Christchurch?
Yes. Whilst we deliver much of our work remotely for efficiency, we provide on-site consulting across Christchurch and Canterbury when needed for hardware installation, network integration, or stakeholder workshops. Initial strategy sessions are typically face-to-face to properly understand your infrastructure and business requirements.
Can Proxmox replace our VMware environment?
Yes, in most cases. Proxmox VE provides enterprise virtualisation with high availability clustering, live migration, backup integration, and web-based management—without VMware licensing costs. We assess existing VMware workloads, plan migration sequences, and execute cutover with minimal downtime. Typically achieves ROI within 12-18 months through eliminated licensing fees.
