An application landscape built for agility, not archaeology.

Most large enterprises run more applications than they need, integrated in ways that were never designed. Application Architecture at DUOARCH starts by understanding the full landscape — then building the rationalisation, migration, and integration strategy that transforms it from a constraint into an accelerator.

Our approach covers the full lifecycle: strategic design of new capabilities, portfolio management of the installed base, cloud-native patterns for what gets built next, and the integration layer that ties it together. Governance is built in so the estate does not re-fragment the moment the engagement ends.

What we deliver

• Application portfolio assessment — a full inventory rated by business value, technical health, and strategic alignment, with a RETIRE/RETAIN/REPLACE/REPLATFORM recommendation per system
• Integration architecture — the API, event, and data integration patterns that decouple systems and allow each to evolve independently
• Platform strategy — the decision framework for buy vs. build vs. SaaS, applied to your specific capability gaps and technology bets
• Cloud-native reference architecture — the patterns, guardrails, and toolchain for applications built or migrated to cloud
• Application governance model — the standards, review gates, and ownership model that prevents the estate re-fragmenting

"We went from 140 applications to 80 in 18 months, and release cadence doubled. The portfolio work was the foundation."
