XDN is a research project that eases developers to deploy stateful web service in the cloud edge to provide lower latency. XDN embraces a declarative approach where you only need to describe what characteristics your service has and what consistency guarantees your client wants, not how to replicate your service in the edge. You do not need to understand Raft, Multi-Paxos, or ZAB protocols to enjoy a linearizability consistency guarantee, XDN handles the deployment for you :)
This project is still under development.
