Azure Application Gateway vs. NGINX Ingress Controller

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.

Best suited if we have to manage external traffic inside your Kubernetes cluster and want to use granular control to your applications.

• 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.

Incentivized

• Provide access to containers
• Manage traffic
• Route traffic
• Lightweight
• Near to zero downtime

Incentivized

• 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)

• Its not related to Ingress functionality but certificate management with cloud vendor would be a feature i would like to see.

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.

We are already using NGINX which is so reliable, it definitely lends weight to our decision to select NGINX Ingress Controller. Also, even though it is a little more complex to manage, NGINX Ingress Controller definitely have a richer feature set, better performance, caching, traffic management among other features which was why it was chosen.

• Positive : Improved performance and scalability
• Positive : Better and enhanced Security
• Positive : Efficiency
• Negative: Cost
• Negative: More resources to manage.

Incentivized

• Security is one of the best objective which we achieve with NGINX Ingress
• Cost optimization is one of the business objective
