The goal of the SwiftCloud project is to propose an efficient
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
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.
