# Redundancy For a higher availability you can install multiple installations of the Invantive Web Service software. These installations can be located on óne server or on multiple servers. With multiple servers you ensure a better availability: even if a server breaks then the users can still keep on working (see image).  The redundancy can be set in the settings.xml file. See also [Connection configuration](invantive-webservice-verbindingsconfiguratie). As soon as a connection is no longer available the programming of your user will try to use a different available connection.
