Design
High-level and low-level design for the estate as it is, and as it should be.
firwat Inc.
The live estate, designed, implemented — then kept assured.
Live-estate architecture for organisations. firwat holds that sequence and stays with the estate once it is running.
The work is architecture and delivery: a source of truth, named decisions, and a retainer that still makes sense after the next change.
Record
As-builts, decision records, and a target-state the organisation can keep.
Retainer
Named time after go-live, so the pattern stays true when the estate changes.
The estate, under one practice.
Read the scope01Networks
Campus, wide-area, and data-centre design, kept as a living as-built.
02SecurityZones, identity-aware paths, and a control set people can explain.
03CyberTechnical authority for logging, escalation, and a major incident.
04AutomationGuarded change, infrastructure as code, and intent-aware operations.
05Public cloudLanding zones on AWS, Azure, and GCP, with identity and a way back.
06SaaS and workplaceMicrosoft 365, Google Workspace, and identity as the control plane.
07On-premises platformsWindows, Linux, hypervisors, and directory services in the same record.
Who holds what
The client owns the estate.
Hardware, tenants, and cloud subscriptions stay on the client’s books. firwat sells the design, the build of the record, and the retainer. The reusable method stays with firwat.
