What’s the difference between CDN and Edge Computing?

Preface – This post is part of the Edge Computing series.


The network configuration is tough to understand, but the technologies bring innovation to the business criteria and industry work. Edge computing has enabled the creation of distribution of resources for organizations closer to the network edge to provide good performance and latency. In this technology, the workload is distributed across different infrastructures located in different regions. In contrast to the statement, CDN is placed over servers to provide cached data, which is more reliable to access. The technology is a way of catching content over the network of distributed servers. The technology is gaining popularity due to its unique and satisfying results in the IT industry. But now the question here arises what the difference between CDN and Edge computing is.

What is CDN?

CDN is popularly recognized as a content delivery network that consists of servers to catch the copied data. The data is distributed over the CDN network and then is processed whenever a user request is made. Due to this architecture process, there is no need to keep the data on a central server. The need for a Central server is avoided due to slow data processing and achieving high latency. It is a group of servers globally distributed over different regions. The server works together to make the work processes simple and easy. The architecture has helped to increase network connectivity. The conventional server is placed near the users over their specific regions.

What is Edge Computing?

Edge computing is a kind of cloud computing that enables data storage and computational data centers near the source of data to provide fast data delivery. Edge computing is not limited to conventional service. The technology helps to perform the calculations and applications automatically without any host server. The technology has brought data resources closer to the edge network, which is designed to fit the needs of the industries. It helps to improve the network performance and scalability of industry processes. It has also helped to reduce bandwidth costs and increase data resource availability. The performance of the websites has also increased and reduced the load times.

Difference between CDN and Edge computing

S. no. CDN Edge computing
1. The content delivery network is placed over the conventional servers near the user or specific regions. It enables the distribution of data resource centers to place closer to the user.
2. It enables catching the content over the server. The technology enables the calculation and running of applications independently without any host server.
3. It does not help to improve any network quality or performance. With the help of the CDN network, the performance of edge computing is improved.


The above article can easily comprehend the difference between edge computing and content delivery network. Despite their differences, some similarities exist, such as both technologies helping improve website performance and reduce loading time. Both technologies also help to increase content delivery and availability. They help in lowering bandwidth costs and increasing user satisfaction. Edge can support AI, ML, and many computing streams.
