Azure Traffic Manager helps improve availability and responsiveness of applications by routing traffic across deployments in different regions using built-in health checks and automatic re-routing. It uses DNS to send users to the closest available endpoint whether that is the primary, a backup, or endpoints weighted by traffic distribution. Traffic Manager supports routing methods like priority, weighted, and performance-based routing to optimize for high availability across Azure and hybrid cloud services.

• Azure Traffic Manager helps reduce downtime
and improve responsiveness of important
applications by routing incoming traffic across
multiple deployments in different regions.
• Built-in health checks and automatic re-routing
help ensure high availability if a service fails.
• Use Traffic Manager with Azure services
including Web Apps, Cloud Services and Virtual
Machines - or combine it with on-premises
services for hybrid deployments and smooth
cloud migration.
• Traffic Manager uses the Domain Name System
(DNS)

3. Traffic routing methods available in Traffic Manager
• Priority: Select 'Priority' when you want to use a primary service
endpoint for all traffic, and provide backups in case the primary or the
backup endpoints are unavailable.
• Weighted: Select 'Weighted' when you want to distribute traffic
across a set of endpoints, either evenly or according to weights,
which you define.
• Performance: Select 'Performance' when you have endpoints in
different geographic locations and you want end users to use the
"closest" endpoint in terms of the lowest network latency.
