HiveMQ MQTT Broker instances scale with the underlying hardware. The non-blocking and multi-threaded approach allows up to 10,000,000 concurrent device connections while maintaining extremely fast throughput and adding minimal latency

Enterprise data integration is achieved through bi-directional transmission of data between a HiveMQ MQTT broker and an enterprise system that act as an MQTT client. Using MQTT pub - sub protocol, each enterprise systems' MQTT client subscribes to the data that needs to be integrated. HiveMQ's MQTT Shared Subscription implementation makes it possible to horizontally scale the MQTT clients so the enterprise integration is scalable and reliable.

An open API and a flexible extension framework makes it possible to integrate HiveMQ and your IoT data into existing enterprise systems. The extension framework allows developers to quickly create extensions for custom data processing, device authentication and device authorization mechanism. HiveMQ also provides a marketplace of pre-built extensions for Kafka, Oracle DB, MongoDB and other systems.

Any MQTT compliant client library can used with HiveMQ. HiveMQ provides our own Java client library but you can also use Eclipse Paho, C/C++ JavaScript or Phython libraries. Some of our customers also create their own custom MQTT clients. Different options for MQTT client means you don't get locked - in to one vendor. 

Unlike HTTP, HiveMQ and MQTT is based on a pub-sub architecture so the total network traffic is reduced since there is no client polling. MQTT message size is also significantly smaller than HTTP so the amount of data passing through the network is reduced.

HiveMQ is designed to secure the IoT data from device to enterprise systems. Data transport is secured by industry standards like TLS 1.3, secure websockets and state-of-the-art cipher suites. Support for authentication and authorization includes, X. 509 certs, username/password, IP-based authentication, and an API that allows for custom authentication, authorization and permission logic such as OAuth 2.0 integration.

Administrators can use HiveMQ dashboard to monitor the real - time data passing through the MQTT broker and MQTT clients connected to your IoT application. For each MQTT client, and administrator can see a 360° overview of the client status, disconnect a client, remove the MQTT session, and add/remove subscriptions. For advanced troubleshooting, HiveMQ allows you to create trace recordings that can be used to identify issues and bottlenecks in your deployed IoT applications. An overall summary dashboard gives an operation team the complete real-time overview of the broker cluster and general health of the system.

HiveMQ can be deployed on a private, hybrid and public cloud. Pre-builit images can be deployed on private clouds using Kubernetes, OpenShift and DC/OS. The supported public cloud platforms includ AWS and MS Azuere. HiveMQ can also run natively on Linux, Windows and OS X.

Data delivery over unreliable networks can be a challenge. HiveMQ implements all MQTT Quality of Service levels, including at most once, at least once and exactly once delivery. HiveMQ's support for advanced message retention policies and offline message queuing are essential to accommodate network latency.

HiveMQ is architected with a truly distributed and masterless cluster architecture, which means there is no single point of failure and the cluster can grow and shrink at runtime without losing data or availability. Support for Kubernetes, OpenShift and DC/OS make it possible to automatically scale HiveMQ to meet the requirement of your IoT applicaiton.

HiveMQ's MQTT broker is 100% compliant with the MQTT 3.1, MQTT 3.1.1 and MQTT 5 specification. We also allow MQTT 3 and MQTT 5 clients to communicate the HiveMQ at the same time. All advanced features like topic wildcards, persistent sessions with offline queuing, retained messages and all Quality of Services levels are available at scale.

HiveMQ Cloud is our cloud native IoT messaging service that simplifies the deployment and management of MQTT platforms. Our fully managed MQTT Cloud Platform creates scalable and reliable MQTT cloud-broker clusters that are built for production - with just a few clicks.
