Azure Application Gateway vs. Azure Load Balancer

For building scalable and highly available applications, Azure Application Gateway does most of the job on behalf of you; automatically load-balancing traffic from a number of users to a number of back-end servers. This ensure scalability and availability. The in-built security is great as can be expected from Microsoft, and user has a variety of tools for monitoring the health of the load-balancing function as well as the health of back end servers behind it.

I don’t like that it's part of the Microsoft brand. In general, I am not a fan of Microsoft products but Azure gets it right.

Other load balancing tools in Azure (Azure LB and Azure Traffic Manager) are limited in their functionality in comparison with the Azure Application Gateway, and also, they don't provide security features. Azure Firewall, although it has security features, is more expensive, and most importantly, it's not a load balancer at all.

• Was able to get better user experience so users won't feel the website is useless.
