| 4 | Die Lernplattform ist eine web-basierte Anwendung und hauptsächlich in Java geschrieben. Folgende Standardanwendungen werden unterstützt: | ||
| 5 | |||
| 6 | * Web-Server: Apache | ||
| 7 | * Applikations-Server: Tomcat | ||
| 8 | * Verwaltung von Daten: PostgreSQL, XML | ||
| 9 | |||
| 10 | Zur Nutzung dieser Lernplattform benötigen Sie eine Internetverbindung sowie einen Browser (Google Chrome, Mozilla Firefox, Internet Explorer, etc). | ||

| 29 | Empfehlung für 300 gleichzeitige Nutzer: | ||
| 30 | |||
| 31 | * 8 GB RAM | ||
| 32 | * 2 CPUs > 2 GHz | ||
| 33 | * 200 GB HDD | ||
| 34 | |||
| 35 | == Software == | ||
| 36 | |||
| 37 | Wir empfehlen Linux (64bit). | ||
| 38 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
| 39 | |||
| 40 | * Scientific Linux | ||
| 41 | * Red Hat Enterprise Linux | ||
| 42 | * Ubuntu | ||
| 43 | * Open Suse | ||
| 44 | * SUSE Linux Enterprise Server. | ||
| 45 | |||
| 46 | Andere Distributionen sind möglich. | ||
| 47 | |||
| 48 | === Softwarekomponenten === | ||
| 49 | |||
| 50 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
| 51 | * Datenbankserver: Postgresql | ||
| 52 | * Applicationserver: Java 17, Apache Tomcat 9 | ||
| 53 | |||
| 54 | === Verteilung === | ||
| 55 | |||
| 56 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
| 57 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
| 58 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
| 59 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
| 60 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
