[infinispan-dev] Auto Scaling for Infinispan

Hi, one more result from the Cloud-TM project that we thought might be interesting for the Infinispan community (and possibly OpenShift). Our last effort is a system for automating elastic scaling for Infinispan, which we named TAS: Transactional Auto Scaler. TAS uses a hybrid methodology combining analytical modelling, for forecasting the effects of data contention, and machine learning techniques (we experimented both with Radial Basis Functions Aritificial Neural Networks and Regression Decision Trees), for forecasting the effects of contention on hardware resources. Applications of TAS range from on-line self-optimization of in-production applications, to the automatic generation of QoS/cost driven elastic scaling policies, and support for what-if analysis on the scalability of transactional applications. Results look pretty good, probably even better than we were originally hoping! ;-) Cheers, Paolo
