Non-Functional Challenges of IoT

Summary

The web content discusses the non-functional challenges faced in IoT solutions within digital transformation initiatives, emphasizing the importance of addressing mobility, scalability, capacity, extensibility, interoperability, network bottlenecks, and connectivity from an architectural perspective to ensure consumer satisfaction and service quality.

Abstract

The article titled "Non-Functional Challenges of IoT" delves into the critical non-functional aspects that IoT solution architects and designers must focus on during digital transformation programs. It highlights that these challenges, which include mobility, scalability, capacity, extensibility, interoperability, network bottlenecks, and connectivity, are vital for ensuring the performance, availability, security, and cost-effectiveness of IoT solutions. The author stresses that overlooking these aspects can significantly impact consumer satisfaction and the ability to meet service level agreements. The article also suggests that IoT applications must be designed to dynamically scale and integrate with a multitude of devices and services, while also being extensible to accommodate future growth and changes in the ecosystem. Furthermore,

Requirements focus from architectural perspective

There are several challenges related to IoT solutions in digital transformation initiatives. The problems are from multiple angles, such as business, architectural, technical, and operational. Quality of services not only affect the financial, commercial, and business concerns but also can have a tremendous effect on consumer satisfaction.

In this article, my purpose is to highlight vital non-functional aspects of IoT which require focus in the digital transformation programs. IoT solution architects and designers must show their leadership in dealing with these challenges starting from the nascent stages of the solution lifecycle.

Even thought all non-functional aspects are important, from consumer satisfaction perspective, the most common non-functional challenges for IoT are mobility, scalability, capacity, extensibility, interoperability, network bottlenecks, and connectivity.

Mobility

Mobility is a common IoT Architecture non-functional aspect affecting the solutions across the modernizing enterprise and transformation programs. IoT devices need to move a lot, and they change their IP addresses and networks frequently based on their locations.

For example, the routing protocols, such as RPL, must reconstruct the DODAG (Destination Oriented, Directed Acyclic Graph) each time a node goes off the network or joins the network, which adds to the system a substantial overhead. These granular technical details, which concern mobility, may have a severe impact on solution performance, availability, security, and cost in digital transformation programs.

Scalability and Capacity Plans

IoT solutions for digital transformation initiatives require overall scalability and capacity plans. IoT applications must integrate with and serve multiple devices in the ecosystem. Managing the distribution of devices across networks and the enterprise application landscape can be complicated.

We may need a dynamic increase or decrease in capacity, coupled with vertical and horizontal scalability and extensibility of the solutions in the enterprise. IoT applications must be tolerant of new services and devices joining the network at a fast speed. Addressing this challenge requires dynamic scalability and enormous extensibility.

Interoperability

Interoperability means that heterogeneous devices, solution components, elements, and protocols need to be able to work with each other harmoniously. Maintaining interoperability in an IoT ecosystem is another challenge owing to the wealth of platforms, solution components, devices, and protocols used in IoT ecosystems.

Network Bottlenecks

Network bottlenecks adversely affect availability, performance, and the cost of products or services in productions, making the service level agreements challenging to meet. Apart from latency related to the distance, several other factors are causing the network bottlenecks.

Some common causes of network bottlenecks are malfunctioning IoT devices, having an excessive number of devices connected to the networks, limited bandwidth, and overcapacity for server, storage, and data utilization.

Several other considerations also need to be made when it comes to connectivity related to IoT solutions in our digital transformation programs; for example, the type of internet services, internet service providers, usage cost, and communication speed.

These are only a few critical non-functional challenges that we need to consider while analyzing the requirements for IoT solutions in digital transformation programs. There are many more concerns that we need to drill down in a granular way methodically.

Quality of services matters for IoT digital transformation solutions both for service levels of the business organizations and the satisfaction of the consumers. As solution architects and designers, we need to find innovative and inventive ways to deal with these non-functional aspects of the IoT solutions in digital transformation programs.
