20 Apr How Does Azure Traffic Manager Work
Traffic Manager does not see the traffic passing between the client and the service. Azure Traffic Manager is a flexible load-balancing solution, which offers plenty of features and methods to route your traffic in a way you deem most appropriate. Endpoint health checking and automatic failover capabilities ensure that your users will never experience downtime or service unavailability due to endpoint failures or planned maintenance. This service allows you to distribute traffic to your public facing applications across the global Azure regions.

Traffic Manager also provides your public endpoints with high availability and quick responsiveness. When you select the priority routing method, it contains a prioritized list Traffic Manager (Dating/Adult) job of service endpoints where the primary service endpoint has the highest priority for all traffic. If the primary service endpoint is unavailable, it redirects the traffic to the second priority endpoint and so on. It uses the DNS to direct clients to specific service endpoints based on traffic-routing rules and procedures. Azure allows you to run cloud services or websites in data centres located all over the world. It enhances application responsiveness by directing traffic to the endpoint with the lowest network latency for the client.
- Step 1) Log in to Azure Portal (Please make sure you have a subscription before doing all this. If you created a free account for the first time, you’ll already have a FREE TRIAL subscription for 1 month).
- In this blog, I have discussed an overview of Azure traffic manager and its different types of traffic-routing methods.
- It helps in improving the response time, availability and performance.
- The client then connects to that IP address to access the service.
- You can only create a CNAME for a domain under ‘contoso.com’, such as ”.

This video also shows what are the Traffic Manager routing methods, how to they solve your networking and routing challenges. With Traffic Manager, you can direct your traffic to endpoints of your choice and avoid downtime for websites during periods of planned maintenance. Bal regions and secure an optimal level of Programming language implementation availability and responsiveness for your services. There are also services fees for traffic view, which is an optional service, and a pricing component for real user measuring, which is also activated at the user’s discretion. Azure Traffic Manager offers six routing methods they are-Priority Routing, Weighted Routing, Performance Routing, Geographic Routing, Multivalue Routing and Subnet Routing. You can select MultiValue for Azure Traffic Manager profiles which may only have IPv4/IPv6 addresses as endpoints.
- After the selection of endpoints, the client is connected directly to the appropriate service point.
- Azure allows you to run cloud services and websites in datacenters located around the world.
- Traffic Manager enables you to continuously monitor your endpoints with automatic endpoint failover, which results in higher availability of your business-critical applications.
- Whatever method for traffic distribution you are using, Azure Traffic Manager performs continuous monitoring of the health of your endpoints using either HTTP, HTTPS, or TCP protocols.
Maximize Your Application’s Potential with Azure Traffic Manager
- It can direct traffic to alternative endpoints while the unkeep is ongoing.
- Azure Traffic Manager is a flexible load-balancing solution, which offers plenty of features and methods to route your traffic in a way you deem most appropriate.
- Step 1 − Select the ‘Traffic Manager’ from the left panel in the management portal that you want to work on.
- Azure Traffic Manager is directing client requests to the most suitable service endpoint by using a DNS (Domain Name Server).
- Traffic Manager provides a range of traffic-routing methods and endpoint monitoring options to suit different application needs and automatic failover models.
It is resilient to failure, including the failure of an entire Azure region. Azure Traffic Manager is a DNS-based load balancer that ensures user traffic is distributed effectively across multiple service endpoints. Whether you run services on Azure, on-premises, or other cloud platforms, Azure Traffic Manager offers high availability, improved performance, and better proximity for users worldwide. This system is particularly useful for applications that require multiple deployments across different regions, as it ensures resilience and minimal latency. Traffic Manager uses DNS to direct client requests to the appropriate service endpoint based on a traffic-routing method.
Combine hybrid applications
The client then connects to that IP address to access the service. Your end-to-end scenarios may benefit from combining these solutions as needed.For an Azure load-balancing options comparison, see Overview of load-balancing options in Azure. Azure provides a suite of fully managed load-balancing solutions for your scenarios.
Prerequisites and Initial Setup
When a question is received for this profile, all healthy endpoints are returned. Step 1 − Select the ‘Traffic Manager’ from the left panel in the management portal that you want to work on. Step 1 − Login to Azure management portal and click ‘New’ at the bottom left corner. Step 1) Log in to Azure Portal (Please make sure you have a subscription before doing all this. If you created a free account for the first time, you’ll already have a FREE TRIAL subscription for 1 month). Apart from this, you can also check my blog 0n Azure Storage Accounts where I have discussed storage account services, types, practical Hands-on on the creation of storage account, and much more.
After the selection of endpoints, the client is connected directly to the appropriate service point. It also enables you to build a highly available application that is resilient to failure, including the failure of an entire Azure region. Let us first understand what is the service provided by Azure traffic manager. Basically, this service balances the traffic load of services hosted in Azure. The routing policy is defined by the client and traffic to the services hosted in Azure is redirected according to set policies.
Traffic Manager and the DNS cache
Your Internet-facing endpoints may operate inside, or outside Azure and Traffic Manager is able to take advantage of several automatic failover models. It will route your traffic even in a scenario in which an entire Azure region is experiencing operational failure. Using nested Azure Traffic Manager profiles, multiple traffic-routing methods are often combined to make sophisticated and versatile rules to scale to the requirements of larger, more complex deployments. Azure Traffic Manager distributes the traffic based on one of the six traffic-routing methods that determine which endpoint is returned within the DNS response. Step 3 − You can change the load balancing method here by choosing a desired method from the dropdown.
