## Introducing the New Cumulocity MQTT Service

 ![scalable-secure-DEVELOPER-FRIENDLY](https://europe1.discourse-cdn.com/flex005/uploads/cumulocity/original/3X/e/9/e9c549e29e47aaf16cbbc5e0dd8c9b39684c347d.jpeg)

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 communicatio** n 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.**

## How to get started

The Cumulocity Managed MQTT Service brings a new level of scalability, security, and flexibility to AIoT messaging.
