Microsoft Fabric and Azure data platforms in Basel: architecture, capacity and cost

Before deciding on a lakehouse, it is worth establishing whether your data actually outgrew an import model or simply outgrew the person maintaining it.

This page is about building a data platform for an organisation in Basel, Microsoft Fabric, Azure Synapse, Data Factory and the lakehouse patterns underneath them, with the local economy taken seriously. Basel's base in pharmaceuticals and biotech, chemicals and process industry, and retail and commercial banking determines the data volumes, the latency requirements and the retention obligations, and those three things decide the architecture. The client population here is shaped by one of the world's most important pharmaceutical clusters and chemicals and life-sciences research.

Does a Basel organisation actually need Fabric?

No single condition justifies a capacity. Several together do: data that no longer fits an import model, a requirement for both SQL and notebook access, multiple teams needing governed self-service, retention obligations beyond what a desktop file can hold, or a Premium capacity you already pay for. One analyst maintaining three import models that refresh in twenty minutes does not need a capacity, and buying one will not improve anything.

What the data actually looks like in Basel

Chemicals and process industry

Continuous process data at high frequency, batch genealogy, yield and energy intensity, with safety and environmental reporting drawing on the same sources. Source systems typically include process historian, batch management system, LIMS, SAP ERP and environmental monitoring.

For a platform design, the consequence is specific. Historian data is retained for months while investigations and environmental questions reach back years. So the architecture has to make the raw grain replayable rather than aggregating at ingestion, and the first serving model should be a batch genealogy and yield model with energy and utilities allocation, which serves production, cost accounting and environmental reporting at once.

Higher education and research

Student lifecycle, research grant and estates data in separate systems, with statutory returns and league-table submissions on fixed annual cycles. Statutory returns and internal management reporting are produced through separate routes, so published figures and internal figures disagree.

Systems to plan for: student records system, research grant management, finance system, virtual learning environment and HR. Student data is personal data with additional duties around special-category attributes, and research data may carry funder-specific restrictions.

Logistics and freight

Event data from scanners, telematics, EDI and transport management systems, each with its own timestamp semantics and time zone handling. Subcontracted volume arrives as spreadsheets, so a third of the network is effectively unmeasured exactly where control is weakest. Drivers' hours records, customs declarations and posting documentation all carry retention obligations and are frequently requested in audit.

A medallion layout for a chemicals and process industry business

The medallion pattern is not complicated, and it is routinely implemented badly: a bronze layer that has already lost fidelity, a silver layer with no testable rules, and a gold layer that is really just the silver layer with different names. Here is how we would lay it out for a Basel client in chemicals and process industry.

Capacity sizing and what it really costs

Fabric capacity is billed by capacity unit. An F2 is roughly US$0.36 per hour pay-as-you-go, about US$260 a month, with around 40 per cent off for a one-year reservation. An F64, the smallest SKU at which report consumers no longer need an individual Pro licence, is roughly US$8,400 a month pay-as-you-go or around US$5,000 reserved.

The arithmetic that matters: F64 only becomes cheaper than per-user licensing somewhere in the region of 350 to 600 readers, depending on the discount you actually pay and whether you reserve capacity. Below that, Pro or PPU per user is normally the right answer, and buying capacity for prestige is a straightforward waste of money.

The sizing exercise is empirical: profile each workload, separate background refresh from interactive query, count real concurrency, find the true peak, then prove the number on a short-lived capacity before anything is bought. The output is a sizing model that states expected utilisation at launch, at double the readers, and the specific point at which you would need the next SKU. Always price from the current Microsoft rate card for your region and agreement. Any figure in an article older than a quarter should be treated as an order of magnitude, not a quote.

Direct Lake, import or DirectQuery

With Direct Lake the model reads Delta directly from OneLake, so there is no refresh to schedule and no query round trip. The catch is the condition attached: anything unsupported falls back, and you are then on SQL endpoint performance without having chosen it. We test it against an import model on your own data and choose on the measured result. In practice Direct Lake tends to win on large, frequently landing tables, which chemicals and process industry workloads often are, while import still wins on smaller models with heavy DAX.

Migrating from what you have now

Few Basel organisations start from nothing. The realistic options are a serving-layer-first adoption, where Fabric takes the gold layer and reporting while existing engineering stays in place, or a domain-by-domain migration with the old platform retained until each domain is validated. What both have in common is that nothing is switched over in a single weekend. Single-weekend cutovers are what produce the rollbacks. The reference pipeline we build first is usually the system that hurts most, which here is normally process historian.

Residency, latency and the Switzerland question

Switzerland North and Switzerland West give in-country residency, which matters more here than almost anywhere else in Europe: banking secrecy, professional secrecy obligations and client expectation all push Swiss data to stay Swiss. Verify per service, because not every Azure or Fabric feature is available in both Swiss regions.

For Basel specifically, Switzerland North (Zurich) is the normal primary with Switzerland West (Geneva) as the pair. Latency from Basel to that region is not usually a constraint for analytical workloads; the constraints that bite are feature availability per region and the processor chain your data protection officer will ask about.

• The revFADP brought Swiss law closer to the GDPR but not identical to it: records of processing, impact assessments and breach notification follow Swiss rules, and an EU-shaped compliance pack needs adapting rather than copying.
• FINMA outsourcing expectations require documented control over cloud providers, including the right to audit and a tested exit plan.
• Article 321 of the Criminal Code and sectoral secrecy duties restrict who may see client-identifying data, which has direct consequences for row-level security design.
