Infrastructure architecture

Design and governance of the shared substrate—compute, storage, networking, voice adjacent systems—so distributed organisations get predictable behaviour instead of per-site improvisation.

Context

  • Hub, branch, and regulated site classes need repeatable patterns with room for local constraints (carriers, power, tenancy).
  • Leadership wants collaboration and file services to work across borders without eroding residency or segmentation expectations.
  • Programmes often mix greenfield standards with legacy PABX, storage, and WAN contracts that cannot all be replaced at once.

Problems addressed

  • Replication lag and split-brain scenarios that local teams cannot diagnose during an incident.
  • Undocumented dependencies between voice, directory, and application layers causing long outages.
  • New sites reinventing VPN, Wi-Fi, and backup because no reference design was adopted.
  • Security baselines that exist on paper but are not validated in deployment templates or change control.

What this work involves

  • Site-class reference architectures with non-negotiable security and monitoring hooks.
  • Network topology and resilience design: failover paths, DNS strategy, and capacity headroom for replication traffic.
  • Data centre and office standards for rack, power, cooling assumptions where relevant; handoff to facilities and local IT.
  • Cross-region deployment patterns with measurable RPO/RTO targets and scheduled restore drills.
  • Runbooks, escalation trees, and demarcation between internal ops, carriers, and integrators.
