We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"IIS is easy to configure in terms of websites and other solutions.""The solution is the easiest way to publish applications which have been designed by older development tools.""The tool shows us the operating systems where our servers and applications are running.""It's very easy to publish.""The product is scalable.""The initial setup is simple.""It has an intuitive user interface and provides a lot of options for building reports.""The interface, simplicity, and ease of management are all good features that make this user-friendly."

"I would rate the pricing a ten out of ten, where one is high price and ten is low price. The pricing is pretty low.""We chose to use Tomcat because it's perfect compared to other containers that we have tested.""The solution integrates smoothly with the development environment. The integration process is straightforward. You only need to configure the project in your IDE. With intelligent features, the integration becomes even easier. Once integrated, deployment into our application is straightforward. Previously, we sometimes relied on manual deployment processes or used a separate application manager. However, with this solution, deployment is simplified.""The most valuable feature is how simple it is to deploy the solution.""The scalability overall is good.""The solution is readily available and open-source.""We can use Apache Tomcat for Java server applications.""It is a robust solution."

Cons
"IIS needs to improve its security. Its support needs to be faster and clear. The tool's licensing could be cheaper as well.""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 product could be more compatible with Linux and macOS, particularly when applying user configuration policies.""The solution's stability needs improvement.""IIS's memory management could be improved.""The platform's stability could be better.""The price of the solution could be less to improve.""There is an issue with the network. The tool's price is also high."

More IIS Cons →

"Tomcat could be a little bit more innovative. Tomcat could come up with a framework that's more lightweight and purely targeted at Java applications.""Vulnerability is one of the areas that can be considered an issue in the solution.""Tomcat needs to improve its user interface.""Our biggest challenge is that the Tomcat servers are not hosted locally.""If it could support the driver's VIN, they can run natively without the GBM. Now, we can run what we call the native cloud application that doesn't require GBM. If Tomcat can support that, it's going to improve performance and backup.""Tomcat's performance is less than other solutions like IBM WebSphere or JBoss.""The disability and memory management is a problem with the solution and has room for improvement.""Performance optimization is an area of concern in Tomcat that should be made better."
