It is possible to deploy the master-controller components / forecasting shells in virtualized environments. It is recommended to contact the Delft-FEWS product management beforehand so that they may advise on virtualization options. The Deltares ICT team has most experience with Delft-FEWS on VMWare VSphere with in-depth knowledge but Delft-FEWS is also known to run on Microsoft Hyper-V. Virtualization of the Delft-FEWS back-end services can generally be done without problems. Best practice is to build small appliances so that the Master Controller , MQ Server (Jboss / ActiveMQ) and Tomcat Servlet Engine (Admin Interface) all have their separate virtual machines. This setup guarantees the individual components do not compete for the same resources such as CPU and memory. Virtualization of the Forecasting Shells is currently not recommended for heavy computational models. When using virtualization, for every logical Forecasting shell there should be a separate virtual forecasting shell server. The number of virtual processor cores issued should never exceed the number of physical cores for forecasting shells.
