Industries on AereA GmbH - Software that still runs in five years

Industrial automation

Service life. A production line runs for twenty years, and the software on it is expected to survive ten of them. That shifts every technology decision: not what is most elegant today, but what will still be maintainable in eight years.

Heterogeneity as the norm. Controllers of different generations and manufacturers sit side by side. Some speak OPC UA, some Modbus, some a proprietary protocol documented only on paper. We have built our own transport implementations for such cases several times.

Energy & e-mobility

Time is the decisive dimension. Energy is a time series problem. What counts is not the instantaneous value but the trajectory - and the forecast. The emphasis is therefore on time series databases, forecasting models and the clean handling of gaps and outliers.

Market data belongs in the control logic. Day-ahead prices from European bidding zones and grid CO₂ intensity are not display values but inputs to the optimisation.

Telecommunications

Real time without a buffer. With voice there is no re-buffering. Latency, jitter and packet loss are immediately audible, which is why QoS optimisation and media path testing are a fixed part of the work.

Exposed components. A SIP network border sits on the open internet and is scanned continuously. DDoS protection, rate limiting and hardened configuration are baseline, not extras.

Automotive

What is technically different in this industry #

Data volumes from the vehicle bus. CAN, FlexRay and automotive Ethernet produce very large, densely timed data volumes during measurement. Analysis tools have to cope without delaying the measurement.

Tools with long histories. Analysis and simulation tools have grown over years, often in C++. Modernisation here almost always means stepwise replacement during operation, not a rebuild.

Medical technology

What is technically different in this industry #

Evidence before speed. What is not documented does not exist in a regulated setting. Test cases, logs and traceability are not overhead but part of the product - which matches how we work anyway.

IEC 62304 shapes the architecture. The standard requires a software safety classification and development and maintenance planning aligned to it. That acts directly on how the software is cut: what is safety-relevant is isolated and evidenced separately.

Public administration

Deadlines come from outside. A change in legislation has a date that is not negotiable. That requires test automation capable of a full regression run in acceptable time.

Accessibility is mandatory, not optional. BITV 2.0 and EN 301 549 are a precondition for procurement. Accessibility testing therefore belongs in system testing, not in a follow-up project.
