Scalability, number of servers
The components mentioned above can all be located on one (powerful) server or each on an individual machine, with all possible configurations in between. It is however common practice to separate the Forecasting Shell server from the Master-controller server. When using multiple machines it is essential that all machines have matching clocks. This can be achieved by making use of one and the same ntp server.
A typical configuration is:
- Master Controller server running Master Controller(s), Apache Tomcat for Admin Interface
- Open Archive Server
- Database Server
- Forecasting Shell Server(s)
Typically in a dual master-controller setup every master-controller has its own machine so that maintenance can take place without offline time.
Virtualization
It is very well possible to deploy the master-controller components / forecasting shells in virtualized environments. 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. Take into account that (not Delft-FEWS related) modelling software may have other requirements or limitations with respect to virtualization of the Forecasting Shells.
Grid computing
FEWS can work with grid computing. Especially when working with heavy computations, e.g. ensemble forecasting or 3d hydraulic computing, this can be an interesting option to explore. It is recommended to contact the Delft-FEWS product management beforehand.
