| 11 | Die Lernplattform ist eine web-basierte Anwendung und hauptsächlich in Java geschrieben. Folgende Standardanwendungen werden unterstützt: | ||
| 12 | |||
| 13 | * Web-Server: Apache | ||
| 14 | * Applikations-Server: Tomcat | ||
| 15 | * Verwaltung von Daten: PostgreSQL, XML | ||
| 16 | |||
| 17 | Zur Nutzung dieser Lernplattform benötigen Sie eine Internetverbindung sowie einen Browser (Google Chrome, Mozilla Firefox, Internet Explorer, etc). | ||

| 50 | Empfehlung für 300 gleichzeitige Nutzer: | ||
| 51 | |||
| 52 | * 8 GB RAM | ||
| 53 | * 2 CPUs > 2 GHz | ||
| 54 | * 200 GB HDD | ||
| 55 | |||
| 56 | == Software == | ||
| 57 | |||
| 58 | Wir empfehlen Linux (64bit). | ||
| 59 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
| 60 | |||
| 61 | * Scientific Linux | ||
| 62 | * Red Hat Enterprise Linux | ||
| 63 | * Ubuntu | ||
| 64 | * Open Suse | ||
| 65 | * SUSE Linux Enterprise Server. | ||
| 66 | |||
| 67 | Andere Distributionen sind möglich. | ||
| 68 | |||
| 69 | === Softwarekomponenten === | ||
| 70 | |||
| 71 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
| 72 | * Datenbankserver: Postgresql | ||
| 73 | * Applicationserver: Java 17, Apache Tomcat 9 | ||
| 74 | |||
| 75 | === Verteilung === | ||
| 76 | |||
| 77 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
| 78 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
| 79 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
| 80 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
| 81 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
