Statistiche sulla latenza round trip della rete di Azure

Questo articolo fornisce statistiche di latenza round trip tra aree di Azure per ottimizzare l'architettura cloud e le decisioni di distribuzione. I dati provengono dal monitoraggio continuo della rete nell'infrastruttura globale di Azure e rappresentano misurazioni delle prestazioni reali.

Usare queste statistiche per:

  • Pianificare distribuzioni in più aree per ottenere prestazioni ottimali
  • Selezionare le aree che riducono al minimo la latenza per gli utenti
  • Progettare strategie di ripristino di emergenza con considerazioni sulla latenza
  • Benchmark delle prestazioni previste tra coppie di regioni specifiche

Che cos'è la latenza di round trip?

La latenza round trip è il tempo necessario per il viaggio di un pacchetto di dati da un punto della rete a un altro e viceversa. Nel contesto di Azure, misura il tempo necessario per il viaggio di un pacchetto tra due aree di Azure. Questa metrica è fondamentale per le applicazioni che richiedono comunicazioni a bassa latenza, ad esempio l'elaborazione dei dati in tempo reale, i giochi e le transazioni finanziarie.

Come viene misurata la latenza?

Azure misura la latenza del round-trip usando sonde di rete interne che monitorano continuamente le prestazioni della rete backbone di Azure. Questi probe inviano pacchetti di dati tra aree di Azure e registrano il tempo impiegato per i pacchetti per spostarsi verso la destinazione e tornare indietro. Le misurazioni vengono raccolte in intervalli di 1 minuto, fornendo una visualizzazione dettagliata delle prestazioni di rete nel tempo.

Le statistiche di latenza presentate in questo articolo si basano sul 50° percentile (P50) di queste misurazioni, che rappresenta il tempo di round trip mediano. Ciò significa che la metà dei tempi di round trip misurati è inferiore a questo valore, fornendo un indicatore affidabile delle prestazioni tipiche della rete.

Dati di latenza di andata e ritorno per regione

Nelle schede seguenti sono indicati tempi di round trip di P50 percentile mensili tra le aree di Azure per una finestra di 30 giorni. La latenza viene misurata in millisecondi (ms).

Il set di dati corrente è stato acquisito il 30 giugno 2025 e copre il periodo di 30 giorni che termina il 29 giugno 2025.

Per facilitare la lettura, ogni tabella viene suddivisa in schede per i gruppi delle aree di Azure. Le schede sono organizzate in base alle aree e poi in base all'area di origine nella prima colonna di ogni tabella. Ad esempio, la scheda Stati Uniti orientali mostra anche la latenza da tutte le aree di origine alle due aree degliStati Uniti orientali: Stati Uniti orientali e Stati Uniti orientali 2.

Importante

Le cifre della latenza mensile tra le aree di Azure non cambiano regolarmente. L’aggiornamento di queste tabelle è previsto ogni 6-9 mesi. Non tutte le aree pubbliche di Azure sono elencate nelle tabelle seguenti. Quando si aggiungono nuove aree online, questo documento verrà aggiornato non appena sono disponibili i dati di latenza.

È possibile eseguire la latenza da macchina virtuale a macchina virtuale tra aree usando macchine virtuali di test nella sottoscrizione di Azure.

Tabelle di latenza per le aree delle Americhe, tra cui Stati Uniti, Canada e Brasile.

Usare le schede seguenti per visualizzare le statistiche di latenza per ogni area.
