## What the models said about NGINX

- "running them on under-powered virtual machines ... creates a bottleneck" (Qwen 3.7 Flash, negative prompt, soft negative)
- "Don't use Nginx for complex load balancing - It's a web server first" (Kimi K2, negative prompt, soft negative)
- "A well-run software load balancer (HAProxy or NGINX) or a cloud-managed service will give you the performance, flexibility, and cost-effectiveness you need" (DeepSeek V4 Flash, scale prompt, first choice)
- "a cloud-based load balancer (if you're in the cloud) or Nginx (if on-premises) represents the best balance of cost, performance, and ease of management" (Claude Haiku 4.5, direct prompt, first choice)
- "The Industry Standard (Flexible & Powerful): NGINX ... If you are moving toward a microservices/Kubernetes architecture, transition to NGINX Ingress." (Qwen 3.7 Flash, direct prompt, first choice)

## What the models said about Azure Application Gateway

- "Use the Application Gateway on Azure or Network Load Balancer (NLB) on AWS if you have strict compliance requirements" (Qwen 3.7 Flash, direct prompt, first choice)
- "If everything is already in Azure and you prefer a managed service, Azure Application Gateway is a natural fit." (MiniMax M2.5, paraphrase prompt, alternative)
- "AWS Elastic Load Balancing (ALB/NLB) or Azure's Application Gateway run directly within your cloud architecture." (Gemini 3.5 Flash, direct prompt, alternative)
