Azure Application Gateway vs. Fastly Next-Gen WAF (powered by Signal Sciences)

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.

Fastly has been the ideal CDN (Content Distribution Network) to solve and optimise the management of our content in our applications and portals; we have easily integrated its use, which has meant an increase in performance, a time savings in terms of management, and a saving of resources that we can use to make further improvements to improve our customers' web experience.

• Easy integration with Load Balancer and Azure Scale Set to provide a full solution for traffic management.
• With rich routing rule, we could use one Application Gateway as the central point for all internal applications to expose to the external network.

• Live examples in the Azure documentation
• Application Gateway UI Blade in Azure Portal can be streamlined
• Have more advanced feature set as WAF (Web Application Firewall)

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.
