Forecasting Shell Server
The forecasting shell server is the server for execution of forecast runs. It contains the modelling software and it's operation is controlled by the Master Controller

• advised internal memory and CPU: Minimum 2 GB RAM and 1 one CPU core per FSS instance, CPU typically Intel Xeon 2.33 GHz or equivalent.
• operating system: Windows 2003 / 2008 / Vista / 7 / 8 / 10, Linux RedHat / CentOS / SUSE contains modelling software (incl. licenses), OS usually dependent on 3rd party modules and modelling software
• amount needed: Minimum 2, more depends on computational load
• a master-controller can use Windows and linux forecasting shells simultaneously

Master Controller Server
The master controller organises task traffic and scheduling

• advised internal memory and CPU: 1 GB RAM per MC instance. CPU typically Intel Xeon 2.33 GHz or equivalent.
• operating system: Windows 2003 / 2008 / Vista / 7 / 8 / 10, Linux RedHat / CentOS / SUSE, Other Unix-like operating systems possible (e.g. HP-UX, Solaris), as long as there is a JDK with the correct version available for the OS. A JMS provider such as JBoss 4 / 5 or activeMQ is required but is allowed to be on a separate server
• amount needed: it is recommended to have one machine per master-controller.

Central Database
This is the central data repository, linked to the master controller. The live system is known to run with the following database versions:

• Oracle 9 / 10 / 11 / 12
• PostgreSQL 8.2 / 8.3 / 8.4 / 9.2 / 9.3 / 9.4,
• MS SQLServer 2000 / 2005 / 2008 / 2008R2 / 2012 / 2014.

This list is not exhaustive, so contact us if you are thinking of using a different database or a different type.

• advised internal memory and CPU: See Database vendor requirements. Typically 1 GB RAM per DB instance and CPU Intel Xeon 2.33 GHz or equivalent.
• The database instance(s) can be a hosted on an existing database server or cluster.
• uses 1 instance for each Master controller

Operator clients
The operator client (Gui) is the user end - thick client, multiplied by copying. The operator client uses a local datastore, MsAccess, Derby or Firebird (default since 2015.02).

• advised internal memory and CPU: none, normal pc
• operating system: Windows 2003 / 2008 / Vista / 7 / 8 / 10, Linux RedHat / CentOS / SUSE
• amount needed: as many as there are clients
• possibilities to use under Citrix

Webserver
The webserver is an optional server that hosts and distributes the webpages generated by Delft-FEWS. Hardware requirements depend on the intended use.

Virtualization
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.
