On-Premise vs Cloud AI in Production: The Comparison
This article explains in practical terms when cloud makes sense and why, for critical manufacturing processes, on-premise AI usually wins on control, availability, and compliance.
The honest answer to "Cloud or on-premise?" is: it depends on what is at stake. For analytical tasks with no data protection implications, cloud is often pragmatic. For production processes with sensitive machine data, recipes, or safety-critical control parameters, it is a structural risk – regardless of how well the service level agreement is worded.
Five criteria where on-premise wins in production
- Latency & availability: Local inference responds in milliseconds – independent of network connectivity, vendor maintenance windows, or regional outages.
- Data sovereignty: Production data, recipes, and process parameters do not leave the company. No US CLOUD Act risk, no disclosure to model providers.
- GDPR & EU AI Act: Local systems are compliant by design – no gray area when processing personal data in hybrid cloud architectures.
- Cost structure: One-time investment instead of ongoing API costs that scale with every additional use case. From ~15 users, on-premise is economically superior.
- No vendor lock-in: You stay independent of price changes, model deprecations, and vendor roadmaps.
OPAIRS is designed as a plug-and-play on-premise system: data lake, SLM inference, BI visualization, and process orchestration in one system – installed locally, with no cloud dependency and no SaaS costs. The deliberate counter-proposal to generic cloud platforms.

OPAIRS Forecasting: Self-Hosted Time-Series Forecasting for Manufacturing
How much material will we consume next quarter, when will energy demand rise, which items will run out? Time-series forecasts answer questions like these – usually through cloud services that production data has to be sent to. OPAIRS has built its own forecasting service that runs entirely on-premise, recommends a model only when it demonstrably beats a simple baseline, and connects with the SQL Agent into one continuous chain: query the data, forecast, evaluate.

OPAIRS SQL Agent: Comparing Six LoRA Adapters for Industrial Databases
Six LoRA adapters, a 26-question catalog spanning PostgreSQL, T-SQL and Apache Iceberg databases, two external reference models: OPAIRS has systematically evaluated its SQL agent. Two Granite adapters lead the field. For production use, however, the deciding factors are not only answer quality but also speed, memory footprint, concurrency and the available context from ERP, MES, PLM and other industrial systems.
