10 | Die Lernplattform ist eine web-basierte Anwendung und hauptsächlich in Java geschrieben. Folgende Standardanwendungen werden unterstützt: | ||
11 | |||
12 | * Web-Server: Apache | ||
13 | * Applikations-Server: Tomcat | ||
14 | * Verwaltung von Daten: PostgreSQL, XML | ||
15 | |||
16 | Zur Nutzung dieser Lernplattform benötigen Sie eine Internetverbindung sowie einen Browser (Google Chrome, Mozilla Firefox, Internet Explorer, etc). | ||

48 | Empfehlung für 300 gleichzeitige Nutzer: | ||
49 | |||
50 | * 8 GB RAM | ||
51 | * 2 CPUs > 2 GHz | ||
52 | * 200 GB HDD | ||
53 | |||
54 | == Software == | ||
55 | |||
56 | Wir empfehlen Linux (64bit). | ||
57 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
58 | |||
59 | * Scientific Linux | ||
60 | * Red Hat Enterprise Linux | ||
61 | * Ubuntu | ||
62 | * Open Suse | ||
63 | * SUSE Linux Enterprise Server. | ||
64 | |||
65 | Andere Distributionen sind möglich. | ||
66 | |||
67 | === Softwarekomponenten === | ||
68 | |||
69 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
70 | * Datenbankserver: Postgresql | ||
71 | * Applicationserver: Java 17, Apache Tomcat 9 | ||
72 | |||
73 | === Verteilung === | ||
74 | |||
75 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
76 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
77 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
78 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
79 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
