Performance evaluation of UML software architectures with multiclass Queueing Network models
TLDR
We propose an approach based on queueing networks models for performance prediction of software systems at the software architecture level, specified by UML. Expand

Server consolidation in Clouds through gossiping
TLDR
The success of Cloud computing, where computing power is treated as a utility, has resulted in the creation of many large datacenters that are very expensive to build. Expand

Design and implementation of a P2P Cloud system
TLDR
We show that gossip-based protocols can be used to maintain an overlay network on top of computing nodes, and to partition the set of resources into multiple slices in such a way that the failure of individual nodes do not compromise the overall structure. Expand
