Cloud & Data

Cloud architecture, migration and data engineering for enterprise and industrial estates — workloads that cannot tolerate casual migration.

  • ISO 9001:2015
  • IEC 62443-3-3 (zones & conduits)
  • Well-Architected frameworks
Overview

Cloud and data engineering grounded in operational reality: estates with OT boundaries, data with export-control and safety implications, and workloads where a failed cutover stops production. We design the architecture, run the migration and build the data platforms — on AWS and Azure — with rollback demonstrated, not assumed.

Scope

What this service covers

Cloud architecture & migration

Landing zones, network segmentation respecting IT/OT boundaries, and migration of engineering and enterprise workloads with rollback plans — on AWS and Azure. Lift-and-shift where it is honest, re-architecture where it pays back.

Data engineering & analytics

Pipelines from operational sources — fleet telemetry, test benches, transaction systems — into governed platforms; data models that survive contact with real data; and analytics that operations and engineering teams actually use.

Industrial data platforms

Historian integration, time-series architectures, and the OT-to-cloud data path designed with the same zone-and-conduit discipline as our IEC 62443 work — telemetry out, no uncontrolled path back in.

FinOps & run-cost honesty

Cost architecture from day one: workload right-sizing, commitment planning and monthly engineering-led cost reviews — because a migration that doubles run-cost is a failure regardless of how smoothly it cut over.

Method

How a cloud engagement runs

The numbering below maps to actual engagement stages — each stage has an entry criterion, a deliverable and a decision point.

  1. Stage 01

    Assessment & target architecture

    Estate assessment, dependency mapping and a target architecture with a costed migration sequence — including which workloads should not move.

  2. Stage 02

    Foundation & first workloads

    Landing zone, identity, network segmentation and guardrails established; first workload migrated as the pattern-setter with rollback demonstrated, not assumed.

  3. Stage 03

    Migration & data platform build

    Wave-based migration and pipeline construction with cutover rehearsals, reconciliation checks and hypercare.

  4. Stage 04

    Operate & optimise

    Cost and performance optimisation with a monthly engineering-led review — run by the team that built the estate, not a separate managed-service silo.

Outcomes

What you walk away with

  • A cloud estate with documented architecture, guardrails and honest run-cost projections
  • Data pipelines with defined ownership, quality checks and OT-safe ingestion paths
  • Demonstrated rollback and reconciliation evidence for every migrated workload
  • A run-cost baseline and optimisation cadence your CFO can hold you to
