Load balancing and security strengthen operations while error handling needs improvement

The most valuable features of NGINX Controller ( /products/nginx-controller-reviews ) include its load-balancing capabilities and security features. I find the security aspect particularly strong, and it allows for application routing and managing index pages efficiently. Overall, these features fit well within a three-tier architecture, which is essential for our operations.

More IIS pros

"NGINX Controller is cheap compared to other solutions, and it offers significant cost and time savings."

Cons

"The cost is a bit too high."

"Sometimes if you are using IIS in large-scale scenarios, meaning that if you are deploying an application within IIS service and you are expecting a large number of users to use this application, you can sometimes find some problems, meaning that the service can shut down by itself unexpectedly if you don't configure your IIS with the correct configuration that can handle this number of users."

"It would be beneficial if you could automate security certificate monitoring with IIS."

"I am using an older version of Windows Server IIS and the general management and navigation to get something done is not as straightforward as I hope it to be. The interface could be improved."

"The level of technical support the solution offers could be improved."

"The areas of this solution that need improvement are monitoring, debugging, and troubleshooting."

"The customer service and support team can be improved."

"IIS's memory management could be improved."

More IIS cons

"The technical support from NGINX Controller is not good. They do not offer quick responses or 24/7 support, which is lacking when immediate assistance is needed."

"We pay a yearly licensing fee for the solution."

"The product's price is not high."

"The tool is included with Windows."

"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."

"The yearly licensing cost is very high. The solution is very expensive."

"The price of the cloud system is a bit high."
