SISFC (Simulator for IT Service in Federated Clouds) is a simulator designed to reenact the behaviour of IT services in federated Cloud environments.


As SISFC was developed in Ruby, you will first need a working Ruby interpreter. Once you have Ruby installed, you can install SISFC through RubyGems:

gem install sisfc

While SISFC should work on MRI and Rubinius without problems, we highly recommend you to run it on top of JRuby. Since JRuby is our reference development platform, you will be very likely to have a smoother installation and usage experience when deploying SISFC on top of JRuby.


To run the simulator, simply digit:

sisfc simulator.conf vm_allocation.conf

where simulator.conf and vm_allocation.conf are your simulation environment and vm allocation configuration files respectively.

The examples directory contains a set of example configuration files, including an R script that models a stochastic request generation process. To use that script, you will need R with the VGAM and truncnorm packages installed.

Note that the SISFC was not designed to be run directly by users, but instead to be integrated within higher level frameworks that implement continuous optimization (such as BDMaaS+).


The SISFC simulator was used in the following research papers:

  1. L. Foschini, M. Tortonesi, "Adaptive and Business-driven Service Placement in Federated Cloud Computing Environments", in Proceedings of the 8th IFIP/IEEE International Workshop on Business-driven IT Management (BDIM 2013), 27 May 2013, Ghent, Belgium.

Please, consider citing some of these papers if you find this tool useful for your research.


The research work that led to the development of SISFC was supported in part by the DICET - INMOTO - ORganization of Cultural HEritage for Smart Tourism and Real-time Accessibility (OR.C.HE.S.T.R.A.) project, funded by the Italian Ministry of University and Research on Axis II of the National operative programme (PON) for Research and Competitiveness 2007-13 within the call 'Smart Cities and Communities and Social Innovation' (D.D. n.84/Ric., 2 March 2012).
