#1. The following are actual events from July 19, 2024. In the UK, broadcaster taken off air. In Germany, hospitals cancel operations. In the US, the Times Square billboards go dark and container terminal suspends services in Poland. #2. IT-based services in broadcasters, hospitals, ports and financial institutions came to an abrupt halt. The global IT outage was caused by a disruption in the cloud services. Once the cloud-connected world came to a sudden stop, one technology took center stage. That was edge computing. #3. What is edge computing? It is a means of processing data using the device where the information is produced, or through a nearby server, instead of a centralized cloud server. #4. Given that ‘edge’ means the periphery, data processing occurs close to the source of data, or near the end user. Without the task of sending data to a central cloud and then receiving the processed data, data can be handled more quickly. #5. With faster processing speed, edge computing is useful in situations where swift decisions are needed. Eliminating the need to send data to the center means a reduction in the costs for data transmission and storage. #6. When all data are stored in a cloud, then the data centers become easy targets for hackers. But when data is processed at the edge, without being transmitted to the cloud, there is a lower risk of data leakage. The more sensitive and personal the collected data is, the safer it would be to ensure it is not stored in a cloud. #7. With cloud systems, a network error in the data center could cause an immediate stop in the device. Edge servers offer stable services of their own ？ unaffected by cloud network conditions. #8. Recently, with the discovery of the limitations of cloud computing, edge computing has emerged as the core domain for real-time services. This is because of the tremendous increase in data that must be processed globally. As the ‘Internet of Things’ continues to evolve, and connect all sorts of devices that exchange data in real time, the volume of data to be processed has grown immensely. #9. The rise of the world’s largest metaverse platform, which has driven up the number of concurrent users, highlighted the role of edge computing. With thousands - even millions - of users generating data simultaneously in real-time, there needed to be a way to process that data as quickly as possible. #10. Cloud computing and edge computing clearly have their pros and cons. But there’s no need to worry about choosing between them. The two systems are not mutually exclusive technologies but are close to being complementary. They can compensate for each other’s weaknesses. #11. Edge data centers process data that require immediate decision-making. Data needing more complex and comprehensive decisions are sent to cloud data centers. #12. Our daily lives are filled with an abundance of data as we transmit it and receive processed data in return. Connected as ever to the cloud and edge, our lives are becoming faster, safer and more convenient.
