Sie können Avi Load Balancer-Profile wie Anwendungs-, Persistenz- und Netzwerkprofile erstellen. Sie können z. B. auch ein einzelnes Persistenzprofil erstellen und dieses einem anderen Team in Ihrer Organisation zur späteren Verwendung bereitstellen.

Diese Beispielvorlagen decken verschiedene Szenarien für die Erstellung von Avi Load Balancer-Profilen ab. Im ersten Beispiel wird die Erstellung einer Vorlage dargestellt, die ein Anwendungsprofil, ein Persistenzprofil und ein Netzwerkprofil enthält. Das zweite Beispiel enthält eine Vorlage mit verschiedenen Typen von Persistenzprofilen, die mit Avi Load Balancer und einem Hilfsprogramm für die Zuteilung von Cloud-Zonen verfügbar sind. Die verbleibenden Beispiele konzentrieren sich auf einzelne Persistenzprofile.

Die Beispielvorlagen decken die Mindestanforderungen für die Erstellung von Avi Load Balancer-Profilen ab. Beachten Sie beim Erstellen von Vorlagen, die für Ihre Organisation relevant sind, dass unter Umständen andere Eigenschaften erforderlich sind.

Weitere Informationen zu Profilen finden Sie im Abschnitt Lastausgleich des VMware NSX Advanced Load Balancer-Konfigurationshandbuchs.

Anwendungs-, Persistenz- und Netzwerkprofile

Diese Avi Load Balancer-Beispielvorlage verwendet ein Anwendungsprofil, ein Netzwerkprofil und ein Persistenzprofil.

Das Anwendungsprofil bestimmt das Verhalten des virtuellen Diensts. Das Netzwerkprofil bestimmt den Typ und die Einstellung des Netzwerkprotokolls. Sowohl das Anwendungsprofil als auch das Netzwerkprofil sind virtuellen Diensten zugeordnet. Das Persistenzprofil steuert die Einstellungen, die dafür sorgen, dass ein Client über einen bestimmten Zeitraum mit demselben Server verbunden bleibt. Es ist an einen Avi Load Balancer-Pool angehängt.
