Web Application Security

  1. DDoS Attack Prevention: Edge functions are employed to detect and mitigate distributed denial-of-service (DDoS) attacks in real time. By processing traffic data at the edge, these functions can swiftly identify and block malicious traffic before it reaches the core network.
    • Case Study: An online retail company leveraged edge functions to enhance their DDoS prevention strategy. By implementing these functions, the company could identify and respond to massive traffic spikes indicative of DDoS attacks, effectively preventing potential service disruptions and maintaining uninterrupted user access to their e-commerce platform.

IoT and Smart Cities

  1. Traffic Management: Cities are leveraging edge computing to enhance traffic management. By processing traffic data at the edge, it eliminates the need to transport large data volumes to centralized clouds, reducing bandwidth costs and latency.
    • Case Study: A notable example is the use of edge computing in the city of Las Vegas, where sensors and cameras were employed to monitor and manage traffic flow, reducing congestion and improving safety.

Live Event Streaming

  1. Reduced Latency in Live Interaction: For video streaming, moving backend processes closer to the video source decreases lag and latency, crucial for interactive live video applications. This is one of only a few edge function uses cases with video streaming. Discover more information on “What is Live Streaming?“.


  1. Real-Time Medical Data Processing: Edge functions aid in processing real-time data from medical sensors and wearable devices. They support the early detection of various conditions, including diabetes and skin cancers, by analyzing data on-site rather than sending it to distant servers​​.
    • Case Study: A healthcare provider used edge computing to process data from wearable heart monitors. This allowed for real-time patient monitoring and immediate alerts in case of any anomalies, significantly improving patient care and response times.

Content Delivery

  1. Proximity to End-Users: Optimized Streaming Services: For media and entertainment platforms, edge functions ensure seamless content delivery. They enable efficient processing and caching of content like videos and web pages close to the user, reducing buffering and improving user experience​.
