Internet of Things

While cloud computing was rapidly making strides worldwide, companies realised that there were certain applications that needed data to be processed right then and there. These applications were on the edge of the organisation’s network and weren’t always able to be connected to the company’s computing network. This led to the emergence of edge computing, which allowed organisations to capture, process and analyse data at the ‘edge’ of the enterprise’s network. This found use in situations where the data had to be rapidly processed for things to continue functioning, like an oil rig drilling in the middle of the ocean.21 The idea with edge computing was to make data processing capabilities available right where they were needed, especially in critical applications. Over time, this has found takers across sectors like healthcare (to process wearable device information) to autonomous vehicles and smart city projects.

An offshoot of the Internet of Things (IoT) was the emergence of the Industrial Internet of Things (IIoT). It refers to the use of this capability specifically in factory and industrial settings where equipment is enabled with sensors for real-time processing of data. IIoT is a convergence of sensors, internet-connected devices and advanced analytics in industrial operations. The main aim of using IIoT-enabled devices is to boost productivity and efficiency in fields like manufacturing, energy, transportation and healthcare, among others. Used primarily to drive operational efficiencies, IIoT has found application in functions like supply chain optimisation, predictive maintenance and automation. By using data collected by the sensors, the system processes and analyses it immediately to enable real-time decision-making.22

More recently though, there have been rising concerns about the potential for causing harm through internet-enabled devices. Instances of a city’s power grid or utilities network being shut down by cyber criminals have become increasingly common in the last few years. As more and more of the world goes digital, this has emerged as an important area of concern for individuals, enterprises and governments alike. Most of us live our lives online and store anything remotely important in the Cloud. What happens when the service provider is under threat or gets attacked is something many of us have experienced first-hand. What this requires now is greater investments and innovation in security architecture and awareness among users on common traps and how to bypass them.

During the Covid-19 pandemic, once the world started coming out of the lockdown, companies started investing more in IIoT devices for automation and remote monitoring of their assets. The increased investments in this space also generated a lot more data on machine health and usage, which companies have used to further boost efficiency. Another recent use case for technology in manufacturing has been the emergence of digital twins. These are virtual replicas of physical assets that are created to simulate actual operations to help with strategic decision-making. Digital twins are adept at predicting failures and breakdowns and also provide an accurate projection on the likely efficacy of an asset.23

练习题

Which scenario best explains why edge computing emerged alongside the growth of cloud computing?

A. IIoT-enabled devices aim to boost productivity and efficiency.
B. IIoT is used in functions such as supply chain optimisation, predictive maintenance and automation.
C. IIoT systems can process and analyse sensor data immediately to support real-time decision-making.
D. After the Covid-19 lockdown period, companies invested more in IIoT for automation and remote monitoring.
E. IIoT mainly prevents organisations from collecting data on machine health and usage.

Which statements correctly connect IIoT data and digital twins in manufacturing? Select all that apply.

A. Data on machine health and usage can be used by companies to further boost efficiency.
B. Digital twins are virtual replicas of physical assets.
C. Digital twins simulate actual operations to support strategic decision-making.
D. Digital twins can help predict failures and breakdowns.
E. Digital twins are physical replacements for all factory machines and do not involve simulation.

Edge computing was developed to replace cloud computing completely, rather than to process data closer to where it is needed in critical or connectivity-limited situations.

The section presents healthcare wearable data processing as an application of edge computing, while IIoT is described as being specifically relevant to factory and industrial settings.

In manufacturing, ___ are virtual replicas of physical assets created to simulate actual operations and support strategic decision-making.

Why did companies increase investment in IIoT devices after the Covid-19 lockdown period, and how did the resulting data help them?

Explain how edge computing, IIoT and cybersecurity concerns are connected in critical industrial or infrastructure settings.

A manufacturing company uses sensor-equipped machines that must respond instantly to overheating on the factory floor, while also storing larger datasets centrally for long-term efficiency analysis. Which combination best explains why the company would use both and ?

A. is used for immediate local processing, while supports scalable storage and broader analytics.
B. is used only for advertising, while is used only for mobile phones.
C. eliminates the need for sensors, while replaces all analytics.
D. is always faster than local processing for critical machine reactions.

Which statements correctly connect with earlier ideas about , , and digital business systems?

A. uses sensors and analytics to improve operational efficiency in industries such as manufacturing.
B. Data generated by devices can support wider efficiency analysis in ways similar to how businesses use cloud-based analytics.
C. proves that internet-connected systems no longer require any security investment.
D. Increased use of connected industrial devices can also increase concerns about data security and system vulnerability.
E. is unrelated to real-time decision-making because all processing must wait for delayed central review.

Because already raised concerns about data privacy, the spread of internet-enabled industrial devices and connected infrastructure also creates a need for stronger security architecture and user awareness.

A is a of a physical asset used to simulate operations and support strategic decision-making, much like earlier digital systems used data and analytics to improve business outcomes.
