Traffic Manager
Azure Traffic Manager is a DNS-based load balancer that automatically directs user traffic to the best-performing application endpoints across different datacenters. It helps improve application performance by managing DNS requests intelligently, ensuring users are routed to the most responsive service location without requiring complex infrastructure changes on the client side.
Choose this service when you need global traffic distribution based on DNS resolution rather than direct IP routing. Be aware that there is no free tier available, meaning you will incur costs immediately upon usage under the pay-as-you-go pricing model, with no initial free allowance to offset early expenses.
