| 135 | == Software == | ||
| 136 | |||
| 137 | Wir empfehlen Linux (64bit). | ||
| 138 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
| 139 | |||
| 140 | * Scientific Linux | ||
| 141 | * Red Hat Enterprise Linux | ||
| 142 | * Ubuntu | ||
| 143 | * Open Suse | ||
| 144 | * SUSE Linux Enterprise Server. | ||
| 145 | |||
| 146 | Andere Distributionen sind möglich. | ||
| 147 | |||
| 148 | === Softwarekomponenten === | ||
| 149 | |||
| 150 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
| 151 | * Datenbankserver: Postgresql | ||
| 152 | * Applicationserver: Java 17, Apache Tomcat 9 | ||
| 153 | |||
| 154 | === Verteilung === | ||
| 155 | |||
| 156 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
| 157 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
| 158 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
| 159 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
| 160 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
