什麼是流量管理員?What is Traffic Manager?

Azure 流量管理員是 DNS 型流量負載平衡器,可讓您跨全球的 Azure 區域將流量最佳分散至服務,同時提供高可用性和回應性。Azure Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across global Azure regions, while providing high availability and responsiveness.

流量管理員會使用 DNS,根據流量路由方法和端點的健康情況,將用戶端要求導向最適當的服務端點。Traffic Manager uses DNS to direct client requests to the most appropriate service endpoint based on a traffic-routing method and the health of the endpoints. 端點是裝載於 Azure 內部或外部的任何網際網路對向服務。An endpoint is any Internet-facing service hosted inside or outside of Azure. 流量管理員提供流量路由方法端點監視選項的範圍,以符合不同的應用程式需求和自動容錯移轉模型。Traffic Manager provides a range of traffic-routing methods and endpoint monitoring options to suit different application needs and automatic failover models. 流量管理員可針對失敗彈性應變,包括整個 Azure 區域失敗。Traffic Manager is resilient to failure, including the failure of an entire Azure region.

注意

Azure 會為您的案例提供一套完整受控的負載平衡解決方案。Azure provides a suite of fully managed load-balancing solutions for your scenarios. 如果您要尋找傳輸層安全性 (TLS) 通訊協定終止 (「SSL 卸載」) 或每一 HTTP/HTTPS 要求的應用程式層處理,請檢閱應用程式閘道If you are looking for Transport Layer Security (TLS) protocol termination ("SSL offload") or per-HTTP/HTTPS request, application-layer processing, review Application Gateway. 如果您要尋求區域性負載平衡,請檢閱負載平衡器If you are looking for regional load balancing, review Load Balancer. 視需要結合這些解決方案,可能有益於您的端對端案例。Your end-to-end scenarios might benefit from combining these solutions as needed.

流量管理員提供下列功能︰Traffic Manager offers following features:

提高應用程式可用性Increase application availability

流量管理員藉由監視端點,以及在端點停止運作時提供自動容錯移轉功能,為重要的應用程式提供高可用性。Traffic Manager delivers high availability for your critical applications by monitoring your endpoints and providing automatic failover when an endpoint goes down.

改善應用程式效能Improve application performance

Azure 可讓您在世界各地的資料中心內執行雲端服務或網站。Azure allows you to run cloud services or websites in datacenters located around the world. 流量管理員藉由將流量導向用戶端網路延遲最低的端點,改善應用程式的回應性。Traffic Manager improves application responsiveness by directing traffic to the endpoint with the lowest network latency for the client.

在不需要停機的情況下執行服務維護Perform service maintenance without downtime

您可以在您的應用程式執行規劃的維護作業,而不需要停機。You can perform planned maintenance operations on your applications without downtime. 正在進行維護時,流量管理員可以將流量導向替代的端點。Traffic Manager can direct traffic to alternative endpoints while the maintenance is in progress.

合併混合式應用程式Combine hybrid applications

流量管理員支援外部、非 Azure 端點,並可搭配混合式雲端和內部部署使用,包括「高載至雲端」、「移轉至雲端」和「容錯移轉至雲端」案例。Traffic Manager supports external, non-Azure endpoints enabling it to be used with hybrid cloud and on-premises deployments, including the "burst-to-cloud," "migrate-to-cloud," and "failover-to-cloud" scenarios.

複雜部署的流量分配Distribute traffic for complex deployments

利用巢狀流量管理員設定檔,可以組合多種流量路由方法,建立複雜且彈性的規則,以符合更大型且更複雜部署的需求。Using nested Traffic Manager profiles, multiple traffic-routing methods can be combined to create sophisticated and flexible rules to scale to the needs of larger, more complex deployments.
