The increasing number of networked devices requires scalable IoT platforms. An MQTT broker such as the one from EMQ creates a stable basis for securely managing data streams and integrating heterogeneous infrastructures. It is primarily offered as a managed service. EMQ handles the entire operation of the broker in the cloud. For companies with individual requirements, the broker can also be rolled out on-premises or in a private cloud and operated by the company itself.
The challenge: Mastering scaling and complexity
The connection of millions of devices generates enormous amounts of data for manufacturers and places high demands on scalable and powerful IoT platforms. When new sensors, actuators, or entire machines and systems are added by customers, the demand for performance and computing power increases. Additionally, many companies face the challenge of geographically distributed locations around the world (e.g., between the USA and Europe). This also requires a robust platform that can adapt to different regional conditions and facilitate global data exchange.
Many companies encounter limitations when it comes to scalability and are looking for a way to relieve their IT teams and limit IT costs. Moreover, the operation of IoT components and solutions requires specialized expertise, which presents challenges for companies—especially in light of the shortage of IT professionals. Many companies operate their platforms themselves, which requires the deployment of large teams (20-40 people) to manage monitoring, development and rollouts. Switching to managed services can take the pressure off these teams and reduce both operating costs and the risk of downtime.
Another challenge is heterogeneous infrastructures. For example, production-related OT systems rely on protocols like Modbus, OPC UA, or Ethernet/IP, while newer devices also natively support MQTT. Older machines, on the other hand, require retrofit solutions to be compatible with modern applications. This necessitates appropriate gateways that enable easy integration.
Another issue is cybersecurity for all OT and IT systems. The increasing connectivity expands the attack surfaces. While there are numerous standards and certifications for security, the effort involved is relatively high. Furthermore, complex business models put a strain on companies in terms of costs.
These factors jeopardize the future viability of an IoT platform. What’s needed is a holistic networking approach that takes into account technical, organizational, and business challenges equally. Otherwise, companies won’t be able to fully leverage the potential of modern IoT applications.
The solution: An MQTT broker as a central hub
EMQ’s MQTT broker provides a solid foundation for making IoT platforms future-proof in an industrial setting. It enables the secure handling of high-frequency data streams. Deployment can be done entirely in a private cloud or as a managed service, reducing internal effort since teams aren’t constantly occupied with managing the broker.
Structure and function of the MQTT broker
EMQ has designed the broker architecture with a focus on maximum performance. For this, the classic programming language C was used, rather than the more commonly used Java. Applications developed in C are often measurably faster than others. The resulting better scalability enables the simultaneous connection of millions of devices without compromising performance or stability, ensuring a smooth data flow.
Support for the native MQTT protocol speeds up the integration of modern devices. Many sensors and machines already have this capability. For older systems, EMQ offers a solution with NeuronEX. This allows legacy devices to be connected to the broker and seamlessly integrated into existing platforms. Retrofit scenarios are made easier as a result. If additional features, such as AI-powered analytics or interfaces to other applications, are needed, they can be added flexibly.
The data does not flow into isolated solutions and allows for central management. This networking creates real added value for internationally operating companies. They benefit from geolinking to connect data across different regions. This creates a unified view of devices in Europe, the USA, or Asia.
Security is a top priority. The MQTT broker protects data exchange with TLS/SSL encryption and X.509 certificates. Strict certifications such as ISO/IEC 27001 or SOC 2 Type II demonstrate that the provider meets established security standards. This allows companies to send confidential information without compromising compliance.
The MQTT Broker as a managed service
The MQTT broker can be used as an on-premise solution or in a private cloud. It is also possible to use it as a managed service. In this case, EMQ takes on the role of Managed Service Provider (MSP) and handles the ongoing operation of the broker, including monitoring, maintenance, and updates. However, the data sovereignty remains with the client of the MSP.
The advantage of a managed service: Users of the broker can focus on their core competencies. They do not need to provide additional IT resources, nor do they need to train or hire new personnel. This leads to cost savings and reduces the burden on in-house IT teams, while maintaining high performance and scalability.
The managed service is available on major cloud platforms such as Azure, AWS, and Google. It is also possible to run it in a private cloud. EMQ offers flexible licensing models for this. Users can scale the service up or down as needed, without interruptions in availability.
This makes the MQTT broker suitable for small, medium, and large companies. It also supports geographical platform connections (geolinking), allowing data to be exchanged across different regions. This feature is ideal for globally operating companies.
Companies can switch at any time between self-managed and managed services. They do not need to commit to one model early on. Those who want to use their own resources initially can do so and then switch to a managed service as their needs grow. This ensures long-term investment protection.
The flexible licensing of the broker allows for billing based on actual usage. This eliminates the need for high upfront investments and adapts dynamically to growing requirements. Companies save infrastructure costs, as there are no rigid capacities left unused, but instead a flexible environment that precisely meets current needs. Up to 40% lower hardware costs show that this efficiency has a positive impact on the budget.
The result: Future-proof IoT platforms
The use of the EMQ MQTT broker provides companies with more security in their future planning for IoT platforms. It enables a flexible, resource-efficient, and reliable infrastructure that can also withstand increasing demands. By additionally offering it as a managed service, internal IT departments are relieved, and costs remain manageable.
With EMQ, it is possible to accelerate complex integration processes, easily provide real-time data, and ensure high security standards. Insights can be immediately integrated into new use cases without lengthy development cycles. The resulting acceleration enhances innovation and leads to better products or more efficient processes.
Companies benefit from a solution that brings efficiency gains and stability. It creates an environment in which innovation and growth are possible without technological bottlenecks. This results in lasting advantages that are reflected in lower costs, improved performance, and a clear perspective for future developments.
