What is Edge Computing?

Findings.co explains the positives and negatives of edge computing


Edge computing is a growing trend in the field of network technology that is changing the way data is processed and analyzed. Instead of relying solely on a centralized server to process data, edge computing brings processing capabilities closer to the source of the data, or the “edge” of the network. This allows for more efficient and effective data processing and analysis, as well as increased performance and reduced latency.


Edge computing has become increasingly popular due to the rise of the Internet of Things (IoT) and other connected devices. These devices generate a vast amount of data that needs to be processed and analyzed in real-time, and edge computing provides a way to do this without overburdening centralized servers.


In essence, edge computing enables smart apps and IoT sensors to perform real-time functions by addressing three related challenges:

  • Remote device connectivity to a network

  • Slow data processing caused by network or computing limitations

  • Edge devices that create network bandwidth issues


By processing data closer to the source (at the edge of the network), edge computing can overcome these challenges and improve efficiency, reduce latency, and enhance the overall performance of the system. This allows for faster and more reliable data processing, making real-time functionality possible.


One of the main benefits of edge computing is improved efficiency. By processing data at the edge, devices can perform some of the computing tasks that would otherwise require a more powerful centralized server. This not only reduces the workload on the server but also reduces the amount of data that needs to be transmitted over the network, resulting in faster processing times and lower latency. Microsoft Azure shared a great example of this, writing, “A security camera in a remote warehouse uses AI to identify suspicious activity and only sends that specific data to the main datacenter for immediate processing. So, rather than the camera burdening the network 24 hours per day by constantly transmitting all of its footage, it only sends relevant video clips. This frees up the company’s network bandwidth and compute processing resources for other uses.” 


Of course, however, there are several risks associated with edge computing. One of the most significant risks is security. With data being processed and stored at multiple edge devices, it can be more challenging to secure the network against potential attacks. This is especially true when it comes to securing data in transit between edge devices and central servers.


Another risk is data privacy. Edge computing involves collecting and processing large amounts of data, which can potentially be used to identify individuals or groups. One of the primary concerns is that edge computing may collect and process personal data, such as personally identifiable information (PII), biometric data, or sensitive information related to health, financial, or other personal matters. This raises concerns about the potential for misuse or unauthorized access to personal information. Another data privacy risk associated with edge computing is the potential for data breaches or cyberattacks. Since edge devices are distributed and may not have the same level of security measures as centralized servers, they may be more vulnerable to attacks. Moreover, edge devices may transmit data over insecure networks or unsecured channels, further increasing the risk of interception or data leakage.


Network connectivity is another potential risk. Edge computing relies on stable and fast network connectivity between edge devices and central servers. If the network connection is unreliable or slow, it can negatively impact the performance of the entire system.


Compatibility issues can also arise with edge computing. Edge devices may be running different operating systems and software, which can create compatibility issues when it comes to integrating them with other devices and central servers.


Finally, managing and maintaining edge devices can be challenging. This includes firmware updates, security patches, and troubleshooting issues. This can be especially problematic in large-scale deployments with many devices spread out over a wide area.


Despite these risks, the benefits of edge computing make it an increasingly popular technology for organizations looking to improve their data processing and analysis capabilities. As the technology continues to evolve, it is likely that many of these risks will be mitigated, making edge computing an even more attractive option for businesses and organizations of all sizes. 


Noting the security issues is important to prevent detrimental damages to companies. To mitigate these data privacy risks, organizations must implement privacy-by-design principles in their edge computing solutions. This includes conducting privacy impact assessments (PIAs) to identify potential privacy risks and implementing technical and organizational measures to address them. Additionally, companies must ensure that they obtain valid user consent for collecting and processing personal data and that they adhere to data protection regulations. Encryption and other security measures should also be implemented to protect data both in transit and at rest, and data monitoring and auditing processes should be in place to detect and respond to security incidents.
