È possibile creare profili di Avi Load Balancer, ad esempio profili di applicazione, persistenza e rete. È inoltre possibile creare, ad esempio, un singolo profilo di persistenza e specificarlo in modo che un altro team dell'organizzazione possa utilizzarlo in un secondo momento.

Questi modelli di esempio riguardano diversi scenari per la creazione di profili di Avi Load Balancer. Il primo esempio mostra come creare un modello contenente un profilo dell'applicazione, un profilo di persistenza e un profilo di rete. Il secondo esempio mostra un modello che contiene diversi tipi di profili di persistenza disponibili con Avi Load Balancer insieme a un helper di allocazione della zona cloud. I rimanenti esempi si concentrano sui singoli profili di persistenza.

Gli esempi di modelli riguardano i requisiti minimi per la creazione di profili di Avi Load Balancer. Quando si creano modelli pertinenti per la propria organizzazione, tenere presente che potrebbero essere necessarie altre proprietà.

Per ulteriori informazioni sui profili, vedere la sezione Bilanciamento del carico nella guida di configurazione di VMware NSX Advanced Load Balancer.

Profili di applicazione, persistenza e rete

Questo modello di esempio di Avi Load Balancer utilizza un profilo dell'applicazione, un profilo di rete e un profilo di persistenza.

Il profilo dell'applicazione determina il comportamento del servizio virtuale. Il profilo di rete determina il tipo e l'impostazione del protocollo di rete. Sia il profilo dell'applicazione che il profilo di rete sono associati ai servizi virtuali. Il profilo di persistenza regola le impostazioni che fanno in modo che un client rimanga connesso allo stesso server per un periodo di tempo specificato. È collegato a un pool di Avi Load Balancer.
