Enhancing Edge Computing with Database Replication.

As the use of the Internet continues to grow explosively, edge computing has emerged as an important technique for delivering Web content over the Internet. Edge computing moves data and computation closer to end-users for fast local access and better load distribution. Current approaches use caching, which does not work wel l with highly dynamic data. In this paper, we propose a different approach to enhance edge computing. Our approach lies in a wide area data replication protocol that enables the delivery of dynamic content with full consistency guarantees and with all the benfits of edge computing, such as low latency and high scalability. What is more, the proposed solution is fully transparent to the applications that are brought to the edge. Our extensive evaluations in a real wide area network using TPC-W show promising results.
