WHY IS THE FUTURE OF COMPUTING ON THE EDGE?

摘要

Edge computing helps overcome the curse of network latency. The origin of Edge computing can be traced back to the 1990s, when Akamai introduced Content Delivery Networks (CDN).A CDN usually uses edge nodes closer to users to prefetch and cache web content. These edge nodes can also perform some content customization, such as adding location-relevant advertising, and more importantly, CDNs save bandwidth through caching. In Edge computing, the data gathering and processing occur at the application source or device, or at least nearby. This proximity could range between the hand-held or local devices and appliances, to point-of-sale or physical units distributed across locations. In fact, the concept of CDN is generalized by Edge computing by leveraging the cloud computing infrastructure.
