Scaling IoT Networks: Ensuring Resilience in a Rapidly Growing Landscape

The IoT market remains in a growth trajectory. According to Transform Insights, the global count of connected IoT devices is projected to rise from US$7.6 billion (€6.39 billion) in 2019 to US$24.1 billion (€20.26 billion) by 2030.

IoT’s rapid expansion is expected to continue, notes Alan Stewart‑Brown, VP EMEA at Opengear. 5G is poised to drive this growth, offering businesses the bandwidth and flexibility required to scale their networks.

Finding a way to scale

With this momentum, organizations are turning to IoT to boost asset utilisation, drive productivity, and unlock real‑time analytics. However, the proliferation of IoT networks raises critical resilience challenges.

Often, the biggest gaps in IoT scaling lie not in the initial rollout—which is usually well‑planned—but in the long‑term maintenance and support of sprawling device networks, many of which are situated in hard‑to‑reach sites.

This shift reverses the 4–5‑year trend that moved complexity from the edge toward the core data centre.

Traditional data centres often lack the capacity to process the massive data volumes generated by IoT devices. Moreover, IoT applications demand low latency, high scalability, reliability, and availability, necessitating network infrastructures that can meet these stringent requirements.

As IoT adoption grows, users worldwide increasingly demand more data, more quickly. Consequently, it is logical for organizations to process data near its source—at the network edge—bringing complexity back to the edge in the coming years.

This shift fuels renewed demand for remote management solutions—out‑of‑band (OOB) technologies, remote provisioning, and automated network operations—to manage distributed infrastructure.

Ensuring a resilient link between the core and edge becomes critical. Organizations must monitor and manage edge equipment while safeguarding the connection to the core network.

An independent management network offers a secure backup access route, enabling rapid, automated software and configuration deployment to devices—ideally without on‑site engineer intervention.

Out-of-band management for IoT scaling

OOB management establishes a dedicated, always‑on, secure network that operates outside the production environment. It supports performance monitoring, alerting, and environmental sensing at remote IoT gateway sites.

Large‑scale deployments benefit from agile network operations—leveraging automation for rapid site provisioning and capacity scaling.

Deploying NetOps Automation with OOB 4G/LTE connectivity lets engineers access remote sites even when the production network is down—or before it is activated—dramatically reducing time and cost for scaling IoT deployments.

Only the best

Edge computing has become essential across IoT use cases. As organizations expand their edge networks, they must deploy robust monitoring and management tools to ensure business continuity, making the choice of top‑tier solutions paramount.

A pivotal component is a smart, remote OOB solution that simplifies management of dispersed devices and delivers genuine resilience—enabling early issue detection and rapid, remote remediation.
