Edge computing is a computing paradigm that brings computation and data storage closer to the edge of the network, i.e., closer to the devices that generate and consume data. This enables web applications to process data more efficiently, reducing the latency and increasing the speed of data transmission. Web applications are becoming more complex, and traditional centralised computing approaches are struggling to keep up with the increased demand for data processing and storage. Edge computing offers a solution to this problem by allowing web applications to process data at the edge of the network, near the device that generated it. The main benefits of edge computing for web applications are:

1. Reduced Latency: By processing data near the device that generated it, edge computing reduces the latency and improves the speed of data transmission. This is especially important for web applications that require real-time data processing, such as video streaming and gaming.


2. Improved Scalability: Edge computing allows web applications to scale more efficiently, by distributing the processing load across multiple edge devices. This helps to avoid bottlenecks and reduces the risk of downtime.


3. Increased Reliability: Edge computing helps to improve the reliability of web applications by reducing the reliance on centralised servers. If a centralised server fails, the edge devices can continue to process data, ensuring that the web application remains available.


4. Enhanced Security: Edge computing enhances the security of web applications by keeping sensitive data closer to the device that generated it. This reduces the risk of data breaches and ensures that sensitive information is not transmitted over long distances.

In conclusion, edge computing is a promising technology for web applications that require real-time data processing, scalability, reliability, and security. By bringing computation and data storage closer to the edge of the network, edge computing enables web applications to process data more efficiently, reducing the latency and increasing the speed of data transmission.
