118 | |||
119 | Wir empfehlen Linux (64bit). | ||
120 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
121 | |||
122 | * Scientific Linux | ||
123 | * Red Hat Enterprise Linux | ||
124 | * Ubuntu | ||
125 | * Open Suse | ||
126 | * SUSE Linux Enterprise Server. | ||
127 | |||
128 | Andere Distributionen sind möglich. | ||
129 | |||
130 | === Softwarekomponenten === | ||
131 | |||
132 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
133 | * Datenbankserver: Postgresql | ||
134 | * Applicationserver: Java 17, Apache Tomcat 9 | ||
135 | |||
136 | === Verteilung === | ||
137 | |||
138 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
139 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
140 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
141 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
142 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
