The Internet of Things (IoT) has broken out from its smart home roots to become a full-fledged game changer in the worlds of cloud computing and data management. As 5G brings a dynamic level of speed and latency to network environments, the number of devices connected to these networks continues to explode, with Statista forecasting that 50 billion IoT devices will be in use globally by 2030.
Often pushed to the edge of the network to maintain optimal network performance and to enhance network security, IoT devices are great data resources that can impact business decisions. Enterprises have adopted IoT to do everything from enhancing productivity to establishing systemwide automation. As we enter Industrial Revolution 4.0 — the great merging of artificial intelligence, IoT, and smart technology to monitor and manage automated processes without human interaction — managing the billions of IoT devices currently operating on cloud networks becomes an essential part of implementing a good IoT strategy.

What is IoT Device Management?
IoT device management is a process that consists of provisioning, authenticating, configuring, controlling, monitoring and maintaining connected devices at scale. These steps allow for administrative monitoring and management of IoT ecosystems, providing notifications to administrators who can remotely troubleshoot problems and perform systemwide tasks, such as firmware updates.
Here is how IoT device management software works:
- Provisioning or device registration adds a device to the system.
- Authentication establishes the device’s identity and ensures that it is secure and trusted in the system.
- Configuration and control of IoT devices establishes firmware attributes and security settings. This allows for remote control of devices during and after deployment, including the ability to update a device’s functionality and firmware.
- Monitoring and diagnostics provide insights into device health and send out notifications of anomalies and other network failures, allowing administrators to quickly and remotely address the problem.
- Maintenance updates connected devices as well as adjust configurations to maintain device health and network security.

Benefits of IoT Device Management Software
IoT device management platforms offer comprehensive control and oversight of IoT devices — an approach that eliminates the headaches of manually and individually monitoring connected devices. In addition to enabling secure device on- and off-boarding, an essential step that permits devices to join a network and securely transmit data, IoT device management platforms offer:
- Efficient and scalable IoT deployments that streamline network monitoring and troubleshooting. For complex IoT device fleets, these platforms serve as a central hub that provide deep-level views into network traffic, device status, and data aggregation that can help diagnose network and device issues.
- Remote management of IoT device fleets. As cyberattacks grow more sophisticated, IoT device management platforms allow users to automatically deploy security updates, customize alerts that indicate network and device anomalies that portend a security breach, and offer real-time, continuous monitoring of devices to help stay on top of security issues.
- Integration with other enterprise applications and data servers using APIs and protocols such as MQTT. This allows enterprises to scale and manage their IoT ecosystems from a single panel as well adjust their IoT infrastructure to accommodate evolving business needs.
