Technology & Development – From the sensor to the dashboard

IoT: from Sensor to the dashboard

MQTT brokers, time-series databases and device management for device fleets – on infrastructure capable of handling millions of measurement values per day.

Why centron

The backend for your device fleet

IoT projects rarely fail because of sensors – it’s usually down to the back-end. These components can also support large fleets.

Ingest – built to last

MQTT brokers and API gateways scale in Kubernetes in line with the number of devices – from a pilot project with 10 sensors to a fleet comprising tens of thousands.

Time series at your fingertips

InfluxDB, TimescaleDB or VictoriaMetrics process streams of measurement data efficiently on NVMe volumes; long-term data is archived in S3.

Devices securely connected

VPN access, VPC isolation and cloud firewalls effectively isolate device traffic from the internet.

Industrial compliance

German customers’ machine data remains in Germany – with a C5 certificate as proof for clients.

From pilot to fleet

An architecture that grows with the devices

The pilot runs on a VM with a broker and database; the fleet will later run in Kubernetes with scalable ingestion, stream processing and Grafana dashboards. Old measurement data is automatically moved to the low-cost S3 archive.

In a nutshell

Which cloud infrastructure is best suited for IoT hosting?

IoT hosting: scalable back-ends for connected devices – MQTT, time-series databases and edge connectivity on German infrastructure. The core component is Kubernetes from €29.99 per month – billed by the hour, with no minimum contract term. This is supplemented, as required, by Volumes and S3 Object Storage. All data remains in Germany: in our own data centres in Hallstadt near Bamberg, certified to ISO 27001 on the basis of IT-Grundschutz and BSI C5:2020 Type 1. New accounts receive a €200 starting credit.

Frequently Asked Questions

How many devices can the backend handle?

The architecture scales accordingly: a pilot runs on a small VM, whilst larger fleets distribute ingestion and processing via Kubernetes – the AutoScaler adds nodes as the number of devices and measurement frequency increase.

How much does it cost to get started?

The starting prices are deliberately low: Kubernetes from €29.99 per month, volumes from €0.05 per GB per month and S3 Object Storage from €5.00 per month. New accounts receive a €200 starting credit valid for 60 days – you can calculate the cost of your specific configuration transparently using the price calculator.

Can this be implemented in a way that complies with the GDPR?

Yes. In IoT scenarios, personal data is often identified without anyone realising – movement profiles can be derived from location, usage or sensor data. At centron, telemetry and data analysis remain in Germany, without having to go via third-party platforms. The data centres are certified to ISO 27001 on the basis of IT-Grundschutz; for ccloud³ / Managed Cloud there is an unrestricted BSI C5:2020 Type 1 attestation. Further details can be found in the Trust Centre.
