Introducing the New Cumulocity MQTT Service
The future of IoT demands more than just connectivity; it demands scalability, security, and developer freedom.
That’s why we’re excited to introduce the Cumulocity Managed MQTT Service; a powerful, next-generation messaging layer purpose-built for industrial-scale IoT deployments.
Designed to handle tens of millions of concurrent device connections with enterprise-grade encryption and compliance, this new service redefines what’s possible for IoT messaging, whether you’re connecting smart devices across the globe or integrating industrial assets behind a firewall.
Built for Scale. Trusted for Security
The Cumulocity MQTT Service introduces an IoT-first messaging layer optimised for today’s complex and distributed environments.
It’s engineered to support massive, multi-tenant ecosystems without compromising on control, security, or performance; validated in production for up to 100 million devices and one million messages per second.
Key Features at a Glance
-
Ultra-Scalable Infrastructure
Built on a horizontally scalable, cloud-agnostic backbone. The service can handle millions of devices with low latency and predictable throughput. -
Enterprise-Grade Security
Security is embedded by design: multi-tenancy, per-device isolation, bi-directional TLS, and X.509 certificate authentication all come standard. Fully compliant with GDPR, ISO 27001, and SOC 2. -
Real-Time Monitoring
A new Messaging Service Monitoring and Management UI provides real-time visibility into topics, traffic, and consumers, enabling fast diagnosis of bottlenecks and misconfigurations. -
Developer-Friendly APIs and SDKs
Integrate with Cumulocity your way, via REST, MQTT v5, or custom microservices, all with a consistent authentication model and open, documented APIs.
Why a New MQTT Service?
The original Cumulocity MQTT endpoint was designed for an earlier generation of IoT solutions, where device types and data models were relatively uniform.
Fast forward a decade, and MQTT is now the de facto standard for IoT, serving everything from battery-powered sensors to industrial controllers.
The new Managed MQTT Service meets that evolution head-on with greater flexibility, throughput, and interoperability.
Speak Your Device’s Language
This service removes earlier limitations like strict topic structures and canonical payload formats. Now you can:
- Send and receive arbitrary payloads on any MQTT topic
- Map device-specific payloads to Cumulocity APIs through custom microservices
- Enable native communication without reformatting every message
It’s MQTT, but flexible. Designed to fit your architecture, your devices, and your use case.
Smarter Operations and Monitoring
Operations teams need insight, not just throughput.
With the new Messaging Service Monitoring UI integrated into the Cumulocity Administration App, you get real-time observability into connected clients, topics, and consumers.
That means faster detection of slow consumers, stuck queues, or message spikes — before they impact production systems.
Designed for Growth
The Managed MQTT Service complements Cumulocity’s existing MQTT Core capabilities.
It provides a new, more flexible path to device integration, ideal for customers whose devices don’t natively use the Cumulocity domain model. Whether you’re:
- An OEM connecting millions of embedded devices,
- An enterprise managing legacy industrial assets, or
- A solution provider running complex, multi-tenant environments,
…the new Cumulocity MQTT Service delivers a secure, scalable, and developer-first messaging backbone that grows with your business.
Launch with Confidence. Scale Without Limits
This release marks more than a product update; it’s a strategic evolution for organisations ready to scale beyond pilots and into global production.
With validated performance for 100 million devices, 99.5 % SLA uptime, and enterprise-grade security built in, Cumulocity provides an MQTT foundation that’s ready for any deployment, from edge to cloud.
Launch with confidence. Scale securely. Build the future of IoT on Cumulocity.
