Statistiques de latence aller-retour réseau Azure

Cet article fournit des statistiques de latence aller-retour entre les régions Azure pour vous aider à optimiser vos décisions en matière d’architecture cloud et de déploiement. Les données proviennent de la surveillance continue du réseau dans l’infrastructure mondiale d’Azure et représentent des mesures de performances réelles.

Utilisez ces statistiques pour :

• Planifier des déploiements multirégions pour des performances optimales
• Sélectionner des régions qui réduisent la latence pour vos utilisateurs
• Concevoir des stratégies de récupération d’urgence avec des considérations relatives à la latence
• Évaluer les performances attendues entre des paires de régions spécifiques

Qu’est-ce que la latence aller-retour ?

La latence aller-retour est le temps nécessaire pour qu’un paquet de données passe d’un point du réseau à un autre et de nouveau. Dans le contexte d’Azure, il mesure le temps nécessaire pour qu’un paquet se déplace entre deux régions Azure. Cette métrique est cruciale pour les applications qui nécessitent une communication à faible latence, comme le traitement des données en temps réel, les jeux et les transactions financières.

Comment la latence est-elle mesurée ?

Azure mesure la latence aller-retour à l’aide de sondes réseau internes qui surveillent en permanence les performances du réseau principal Azure. Ces sondes envoient des paquets de données entre les régions Azure et enregistrent le temps nécessaire pour que les paquets se déplacent vers leur destination et leur retour. Les mesures sont collectées à intervalles de 1 minute, fournissant une vue détaillée des performances réseau au fil du temps.

Les statistiques de latence présentées dans cet article sont basées sur le 50e centile (P50) de ces mesures, qui représente le temps d’aller-retour médian. Cela signifie que la moitié des temps d’aller-retour mesurés sont inférieurs à cette valeur, fournissant un indicateur fiable des performances réseau classiques.

Données de latence aller-retour par région

Les onglets suivants affichent les temps d’aller-retour mensuels du percentile P50 entre les régions Azure sur une période de 30 jours. Les valeurs de latence sont en millisecondes (ms).

Le jeu de données actuel date du 30 juillet 2026 et couvre la période de 30 jours se terminant le 30 juillet 2026.

Pour plus de lisibilité, les tabulations divisent chaque table en groupes de régions Azure. Les onglets organisent les données par région, puis par région source dans la première colonne de chaque tableau. Par exemple, l’onglet Est des États-Unis affiche également la latence de toutes les régions sources vers les deux régions Est des États-Unis : Est des États-Unis et Est des États-Unis 2.

Chaque valeur de latence est directionnelle. La latence d’une région à une autre peut différer de celle dans le sens inverse, car le trafic peut emprunter un chemin réseau différent dans chaque sens. Lorsque vous comparez les régions, utilisez la valeur qui correspond à la direction dans laquelle votre trafic circule.

Comment lire les tables de latence

Chaque tableau indique la région source dans la première colonne et chaque région de destination sur la ligne du haut. Pour trouver une valeur de latence, localisez la ligne de votre région source, puis lisez jusqu’à la colonne de votre région de destination. La valeur correspond au temps aller-retour de P50 (50e percentile, ou médiane) en millisecondes.

Par exemple, dans l’onglet Est des États-Unis , la ligne source pour les États-Unis Est et la colonne pour la destination Est US 2 affichent une latence de 8 ms. Comme la latence est directionnelle, le chemin inverse utilise une valeur différente : la ligne pour la source Est US 2 et la colonne pour la destination Est US affichent 9 ms. Utilisez toujours la valeur qui correspond à la direction dans laquelle votre trafic circule.

Pour mesurer la latence entre vos propres charges de travail plutôt qu’entre régions, consultez Test de latence réseau VM pour exécuter un test de latence VM-to-VM dans votre abonnement Azure.
