-You can deploy your application across [Availability Zones](../reliability/availability-zones-overview.md) in a single Azure region to achieve higher availability, but sometimes, you may need to deploy your applications in multiple regions, either to achieve a higher resiliency, a better performance for users across the globe, or better business continuity. There are different approaches that can be taken to direct users to one of the locations where a multi-region application is deployed to: DNS-based approaches such as [Azure Traffic Manager](../traffic-manager/traffic-manager-overview.md), routing-based services like [Azure Front Door](../frontdoor/front-door-overview.md), or the [Azure Cross-Regional Load Balancer](../load-balancer/cross-region-overview.md).
