When reviewing load balancing and routing solutions in Azure, it’s an important thing that you understand how to choose the right service based on specific needs.
Start by looking at the type of traffic. Is it a web app or an internet-facing service? That’s the first decision point.
From there, think about whether the solution needs to be global or regional.
For global reach and performance optimization, you may want to use something like front door.
Whereas for regional scenarios, you may want to use an app gateway or load balancer or even traffic manager.
Also consider availability requirements. When services offer built-in high availability, which ones are they?
Other things that you want to look at: Don’t forget to weigh the cost and feature sets. Some solutions are more budget-friendly but may lack advanced routing or security features. Others, like front door application gateway, offer more control but at a higher price point.
So understand the solutions that are available, the key differences between them, and also always factor in cost.
