IoT Platform Development

Managed services such as AWS IoT Core or Azure IoT Hub reduce operational effort and integrate well with their clouds, which suits most teams. Open-source brokers and network servers give more control, portability and sometimes lower cost at very large scale, but require more operations work. We compare both for your fleet size, regions, protocols and skills, and often recommend a managed core with portable abstractions.

Each device gets a unique identity, typically an X.509 certificate, ideally stored in a secure element. Communication is encrypted with TLS, permissions are scoped so a device can only publish and subscribe to its own topics, and firmware is signed and updated over the air. We monitor for unusual behavior, support certificate rotation and revocation, and align with baselines such as ETSI EN 303 645.

Updates are signed, delivered in stages to small groups first, and monitored for failures before wider rollout. Devices verify signatures before installing, keep a fallback image and report success or failure back to the platform. If error rates rise, the rollout pauses or rolls back automatically. We design this process together with your firmware team.

Managed brokers and well-designed open-source clusters can scale to very large fleets. The practical limits come from design: topic structures, message rates, storage choices and provisioning flows. We size every component for your target fleet with headroom, and verify the design by load testing with simulated devices at and above expected volumes before go-live.

Running costs depend mainly on the number of devices, message frequency and size, storage retention and the services used. We build a cost model per device during design, then reduce cost through edge filtering, batching, appropriate reporting intervals and tiered storage. Dashboards track actual cost per device so you can see trends early.

A proof of concept with real devices can usually be delivered in several weeks. A production-ready platform with provisioning, device management, OTA updates, rules, APIs and monitoring typically takes a few months, depending on scope and integrations. We deliver in sprints with demos and weekly written updates, so you can connect pilot devices well before the full platform is finished.

Yes. We design an abstraction layer that maps vendor-specific payloads and protocols into a common data model, so applications work with normalized device types rather than individual products. New device types are added through adapters or decoders without changing business applications. This approach makes it easier to dual-source hardware, replace discontinued devices and integrate sensors already installed by other vendors.
