Advisory & Architecture — Build vs. Buy. Microsoft vs. Independent.

Strategic tech decisions are rarely as binary as they look in conference rooms. We help mid-market companies ask the right questions — and come with answers grounded in implementation reality, because we'd be the ones writing the code the next day.

We build ourselves · so we recommend from experience Microsoft & Open Source in one hand Workshops 3–10 days Roadmaps with implementation reality

Managing Directors · Owners

Architecture is a business decision, not a technical one.

What does this decision cost over the next 5 years? Which choice is reversible, which locks us in? We deliver workshop results in the language you can defend at shareholder meetings: from architecture clarification to roadmap workshop, each as a fixed price (prices on request). The result is always a document, not a PowerPoint.

Department Heads · Business Lines

Build-vs-Buy, Microsoft-vs-Open-Source — decided in a structured way.

You need to justify a software decision internally. We deliver assessment matrices with target-vs-actual comparison, cost-benefit analysis, compliance mapping (NIS2, EU AI Act, ISO 31000), risk register. Discovery Spike as the typical first engagement (price on request) — followed by the right format (compact, standard, or roadmap workshop).

IT Leadership · CIO · Solution Architect

Specifications, not slides. ADRs instead of marketing.

Architecture Decision Records (ADRs), tenant strategy, data model, security architecture, integration mapping, RACI matrix, ALM pipeline concept. Sovereignty assessment (EU LLM fallback, data localization, Microsoft CSP routing). You talk directly to solution architects who own the implementation themselves.

For Managing Directors · 5-year TCO in euros

What does this architecture decision cost over the next 5 years — and which one locks us in?

Fixed-price workshops from architecture clarification to roadmap with implementation reality (prices on request). The result is always a management-ready document outcome — no PowerPoint theater. You get a 5-year TCO, reversibility assessment per decision, vendor lock-in risks in euros, and a clear recommendation you can defend at the shareholder meeting.

For Department Heads · Build-vs-Buy assessment matrix

Build vs. Buy, Microsoft vs. Open Source — decided in a structured way, defensible in the steering committee.

We deliver an assessment matrix per option: target-vs-actual comparison, 5-year cost-benefit analysis, compliance mapping (NIS2, EU AI Act, ISO 31000), risk register. Discovery Spike as the typical first engagement (price on request) with a documented outcome report — ready for CFO, procurement, and steering committee. Then the right format: compact, standard, or roadmap workshop.

Four strategy questions

What we typically clarify.

Rarely does someone arrive with a clearly formulated question. Usually it's a mix of these four topics — which we untangle and make answerable.

1 · Build vs. Buy

Standard software, customization, or in-house development? We evaluate per use case based on total cost of ownership over 5 years, differentiation potential, market maturity of the standard solution, and your internal team. Rarely is the answer 100% build or 100% buy — usually a mix with a clear interface architecture.

2 · Microsoft vs. Open Source

Microsoft 365, Power Platform, Dynamics 365 — or an open stack with Next.js, Postgres, an open-source identity solution? Both directions have good arguments. We make the decision visible through total cost, skill availability, vendor lock-in risk, and compliance requirements.

3 · Cloud provider choice

AWS or Azure? Hetzner or STACKIT? With or without an on-prem share? The answer depends on compliance, latency requirements, and cost scaling. We know the strengths and gaps of the main EU providers (Hetzner, STACKIT, OVHcloud, IONOS, Open Telekom Cloud) from production projects.

4 · Sovereignty score

How EU-sovereign is your current stack? Which components would be at risk in a serious US Cloud Act scenario? Which migration costs would arise? We give you a score across hosting, identity, data storage, key management, and contractual posture.

Three workshop formats

From architecture review to 2-week Strategy Sprint.

Which format fits depends on how big the question is and how concrete the follow-on implementation plan should look.

Who we are

We recommend from experience — not from theory.

arades GmbH has been rooted in the Microsoft world since 2003 — Microsoft Partner, with our own productized solutions on Microsoft Dynamics 365 (PSA, Intercompany, Teams integration, License Cost Calculator). We've seen at least as many license audits, migration projects, and customization repairs as any larger mid-market partner.

In parallel we run our second pillar — custom software on TypeScript stack, AI integrations beyond Microsoft Copilot, EU hosting with Hetzner and STACKIT. We build the License Cost Calculator at licenses.arades.de in exactly the architecture we'd recommend to clients.

This dual role is the value for strategy engagements: when we say "in your constellation Microsoft is the right choice", we also know what it means to actually set up, run, and hypercare the system. When we say "Open Source is better here", we know what Hetzner setups, GitHub Actions pipelines, and PostgreSQL optimization cost in real projects.

There are consultancies that only work with slides. There are implementation firms that always bend the strategy question toward their favorite platform. We sit in between — and that's the position mid-market companies need in uncertain tech phases.

Honestly speaking

When we won't take you on.

Pure PowerPoint consulting. You want a deck for the board presentation without subsequent implementation? There are very good strategy consultancies for exactly this use case. We are not one of them — we deliver diagrams, ADRs, and roadmaps, but no management slide costume.

"Make-a-deck" requests. If the engagement is "build us a nice architecture slide", we decline. Architecture without an implementation anchor is wallpaper.

Validation of a decision already made. If management has already decided internally and we're only supposed to provide a stamp — please say so openly. An honest strategy discussion won't be possible then, and you'd pay for something you already have.

Enterprise engagements beyond our scale. We are clearly a mid-market partner. Multi-site projects with hundreds of stakeholders, multilingual translation logistics, and 4-hour steering committees — that's what Big 4 firms exist for. We deliver value up to typical mid-market enterprise complexity, not beyond.

If you don't want to reflect implementation reality. Strategy without implementation understanding is folklore. If the follow-on engagement is deliberately never going to happen, our value proposition misses — we recommend not consulting at all then.

What we deliver

Concretely in the Strategy Sprint.

Architecture diagrams

Current and target picture as a layer model, with data flows and interfaces. Machine-updatable in Mermaid or Draw.io — no click-by-click slides.

Decision tables

Build-vs-Buy matrix per use case, with TCO estimate, risk assessment, differentiation value. So even Managing Directors without a tech background can make a well-founded decision.

Architectural Decision Records

Per major decision a short ADR with context, options, rationale, and consequences. So future engineers (yours or others') understand why something was decided as it was.

Roadmap with waves

18–24 months, divided into 3–5 waves, with capacity needs, investment corridor, and dependencies. Always with implementation reality — not at wish speed.

Vendor comparison

When concrete vendor selection is at stake (cloud, SaaS, ERP, CRM), we deliver a structured comparison along the criteria that matter to you — not a Gartner chart.

Sovereignty score

5-dimensional score across hosting, identity, data, keys, and contracts. With migration effort and prioritization. Makes "digital sovereignty" tangible rather than degrading it to marketing vocabulary.

Frequently asked questions

What clients ask before a strategy workshop.

Which strategy questions do you typically clarify?

Build vs. Buy (standard software or in-house development?). Microsoft vs. Open Source (Microsoft Cloud or open stack?). Cloud provider choice (AWS/Azure vs. Hetzner/STACKIT vs. on-prem?). Sovereignty score (how EU-sovereign is your current stack — and how important is that for your business model?). Plus the follow-on migration roadmap.

What does an architecture workshop cost?

Architecture Review (3–5 days) as a fixed price. Sovereignty Audit (1 week) as a fixed price. Strategy Sprint (2 weeks) as a fixed price. For larger enterprise engagements we calculate individually. Investments are partially credited if a follow-on implementation results.

Who attends a Strategy Sprint?

On our side typically a senior solution architect plus a domain specialist (for Microsoft, AI, or custom software, depending on focus). On your side we recommend a Managing Director, IT Leadership, and a business owner. The format works with 4–8 people — larger rounds turn into slide shows.

Can you also advise independently between Microsoft and Open Source?

Yes, that's the core of our Architecture & Strategy offering. We are a Microsoft Partner — but our second pillar Independent Engineering exists precisely to think platform-independent. When the honest answer is "Open Source is better here", we say so.

What sets you apart from a large strategy consultancy?

We build ourselves. So we recommend from experience with code, hosting, and adoption — not from market models or Gartner quadrants. Our workshops have a clear implementation endpoint. If you want to leave the workshop "with an idea", we're not the right fit. If you want to decide and build afterwards, we are.

Which industry experience do you have?

Mid-market manufacturing and trade (with and without Microsoft Dynamics 365), associations and chambers, educational institutions, professional services. Weaker experience in health care (pharma compliance), public sector (BSI requirements), banking (BaFin regulation) — there we refer to specialized partners.

Do you also deliver a PowerPoint deck in the end?

We deliver architecture diagrams, decision tables, ADRs (Architectural Decision Records), and a roadmap outline. Pure "make-a-deck" requests we decline. There are consultancies that do this well — we're not one of them.
