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 | ||

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 | ||
