Streamlining Worldwide Application Distribution through Azure Traffic Manager

Streamlining Worldwide Application Distribution through Azure Traffic Manager

In the ever-evolving digital landscape, ensuring high availability and cost-effectiveness is paramount for global application deployment. One solution to achieve this is by implementing Azure Traffic Manager.

Key Steps to Implement Azure Traffic Manager

1. Create Azure Web Apps in multiple regions:
2. Create your web apps (App Services) in desired Azure regions to host your application globally. This enables deployment redundancy and reduces latency by serving users from the nearest region.
3. Create a Traffic Manager profile:
4. Go to the Azure portal, create a Traffic Manager profile. Provide a unique DNS name for the profile, select the routing method, and choose your subscription and resource group. The Traffic Manager service is global and not tied to a particular region.
5. Add endpoints to the Traffic Manager profile:
6. Add your Azure Web Apps as endpoints in the Traffic Manager profile. Specify the endpoint type, select the app, and define priority or weight if applicable. Optionally, include a global fallback endpoint configured with "All (World)" geographic endpoint to avoid traffic black holing and ensure availability if a region fails.
7. Configure DNS to use Traffic Manager:
8. Update your domain's DNS to point to the Traffic Manager DNS name. This allows incoming client traffic to resolve via the Traffic Manager profile, enabling global distribution and failover according to the routing method.

Ensuring High Availability and Cost-Effectiveness

• Deploying across multiple Azure regions ensures redundancy and low latency.
• Using Traffic Manager’s routing policies like Priority or Weighted can optimize availability and cost; for example, sending most traffic to cheaper or more available regions while having failover to others.
• Monitoring endpoint health lets Traffic Manager route traffic only to healthy instances, avoiding downtime.
• You can start with a few regions and scale out as needed, controlling costs by selectively enabling endpoints or scaling Web Apps based on demand.

The Traffic Manager Setup

• The Traffic Manager was verified to have endpoints that are online and operational.
• The Traffic Manager Profile was chosen from the Azure marketplace with the name 'trafficmanager2451'.
• The Protocol for the Traffic Manager was set to HTTPS with port 443.
• Two endpoints were configured: one as an Azure Endpoint with a priority of 1 (primary) and designated for the first App Service, and another as an Azure Endpoint with a priority of 2 and designated for the second App Service.
• The Priority routing method was selected for the Traffic Manager Profile.

Successful Implementation

• The application was successfully browsed through the Traffic Manager URL, which redirected to the West Europe region app when the East US web app was momentarily stopped, demonstrating the effectiveness of the Traffic Manager in ensuring high availability and efficient traffic distribution across global applications.

Technology plays a crucial role in this implementation by providing tools like Azure Traffic Manager, which enables high availability and cost-effectiveness for global application deployment in the evolving digital landscape. With Traffic Manager, businesses can optimize availability and cost by implementing features such as priority or weighted routing, monitoring endpoint health, and scaling out according to demand. For instance, sending most traffic to cheaper or more available regions while having failover to others can help minimize costs and maximize performance.
