Cloud & Hybrid Architecture

Workload placement, tenancy and the segmentation that ties cloud back to the enterprise — evaluated against recovery objectives and what they cost.

Also known as AWS, Azure, Multi-Cloud, Landing Zone

Left to right is time. Each row is one of the 10 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Hybrid and multi-cloud architecture across AWS and Microsoft Azure: migration strategy, workload placement, tenancy and landing zone design, and the segmentation tying cloud workloads back to the enterprise estate.

Hosting models were evaluated against recovery objectives and the cost of meeting them rather than against a platform preference.

  • Career Reference Record — Design, Build and Publishing PlatformApril–September 2026A cross-linked reference work built as a derived graph: edges declared once, every index, backlink and chart generated from them, published static with per-document access control.
  • Client Architecture Portfolio2024–202688 numbered engagements across two years, twenty-plus live at any moment, across healthcare, manufacturing, financial services and the public sector — the inverse of nineteen years inside one estate, and a different problem.
  • Commercial Site Rebuild and Live Domain MigrationApril–September 2026Twenty pages moved off a hosted page builder onto a static build, and a live domain repointed to a new host without touching any of the six records carrying its mail.
  • ISP Cutover, Public IP Renumbering and WAN Modernization2022–2023An estate moved to a new provider and a new public address space, then modernized for remote and hosted working without dropping the applications the business ran on.
  • Oracle ERP Program — RFP to Cloud Go-Live2011–2023Twelve years from the 2011 request for proposal to a 2020 cloud go-live — the cost model that had to exist first, and a cutover instrumented so neither side could blame the other.
  • Solid Waste Systems Modernization2014–2023Legacy route, fleet and scalehouse systems replaced and integrated to cloud, sequenced around an operation with no slow season.
