SwiftCloud

The goal of the SwiftCloud project is to propose an efficient storage system for cloud environments.
To this end, we intend to leverage the properties of Conflict free Replicated Data Types (CRDTs). CRDTs allow data to be replicated at multiple sites and be updated indendently with the guarantee that all replicas converge to the same value. In a cloud environment, this allows a user to access the data center closer to the user, thus optimizing the latency for all users.

SwiftComp is the twin project focusing on developing efficient techniques to process large ammount of data.
