| 53 | Empfehlung für 300 gleichzeitige Nutzer: | ||
| 54 | |||
| 55 | * 8 GB RAM | ||
| 56 | * 2 CPUs > 2 GHz | ||
| 57 | * 200 GB HDD | ||
| 58 | |||
| 59 | == Software == | ||
| 60 | |||
| 61 | Wir empfehlen Linux (64bit). | ||
| 62 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
| 63 | |||
| 64 | * Scientific Linux | ||
| 65 | * Red Hat Enterprise Linux | ||
| 66 | * Ubuntu | ||
| 67 | * Open Suse | ||
| 68 | * SUSE Linux Enterprise Server. | ||
| 69 | |||
| 70 | Andere Distributionen sind möglich. | ||
| 71 | |||
| 72 | === Softwarekomponenten === | ||
| 73 | |||
| 74 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
| 75 | * Datenbankserver: Postgresql | ||
| |
24.1 | 76 | * Applicationserver: Oracle Java 8, Apache Tomcat 8 |
| |
18.1 | 77 | |
| 78 | === Verteilung === | ||
| 79 | |||
| 80 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
| 81 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
| 82 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
| 83 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
| 84 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
