Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.1
Organizations found IIS provided positive ROI, cost savings, and accessibility, particularly benefiting security and cloud-based pay-as-you-go models.
Sentiment score
6.5
JBoss EAP offers cost-effective, stable deployment with quick ROI and financial benefits, especially for larger-scale implementations.
This flexibility translates to a lower total cost of ownership.
 

Customer Service

Sentiment score
6.5
Many users find IIS support satisfactory but face delays, relying on community resources and Microsoft documentation for help.
Sentiment score
6.6
Red Hat JBoss EAP support is professional and reliable, with good documentation and community resources but email support can be slow.
Microsoft provides a lot of online documentation to consult before speaking to an expert.
There are typically no significant issues.
We receive support from RDS and Red Hat, and the response time and quality meet our expectations.
 

Scalability Issues

Sentiment score
7.1
IIS scalability depends on setup and configuration, supporting thousands but requires careful planning for large deployments.
Sentiment score
7.0
Red Hat JBoss EAP offers reliable scalability, efficient memory management, and smooth performance, ideal for dynamic, high-demand environments.
I would rate the scalability of IIS as a six, mainly due to integration issues since it cannot integrate with other environments.
It depends on the server environment and the presence of a UPS for power backup.
 

Stability Issues

Sentiment score
7.8
IIS is stable and reliable, though compatibility with non-Microsoft technologies presents occasional performance issues and improvement suggestions exist.
Sentiment score
7.5
Red Hat JBoss EAP is highly rated for reliability, particularly after cloud migrations, despite occasional deployment issues in development.
I would give it a nine out of ten for stability.
I would rate IIS's stability as an eight out of ten.
It is quite stable for our needs.
 

Room For Improvement

IIS faces compatibility, setup, monitoring, and cost issues, needing enhancements in scalability, security, UI, and open-source support.
Red Hat JBoss EAP needs improved customization, integration, cost efficiency, support, and user-friendly features for modernization and reliability.
It's influenced by the server's service performance.
If I compare IIS to other web servers such as Apache, which can be deployed in other environments like Linux, I find IIS is mostly used for simple things.
Making it lighter and more modular would probably be beneficial.
I would like to see improved booting of applications altogether on one page to manage all data instances from one location, similar to an AWS console.
 

Setup Cost

Enterprise buyers find IIS cost-effective with Windows Server, appreciating licensing flexibility despite some complaints about overall expense.
Red Hat JBoss EAP offers flexible subscription pricing, seen as cost-effective compared to Oracle WebLogic and IBM WebSphere.
If you have a Windows license, there is no additional cost for IIS.
JBoss is the cheaper option out of the three when compared to WebSphere and WebLogic.
The price is somewhat high for an enterprise, however, it depends on organizational negotiations.
 

Valuable Features

IIS is valued for its integration, security, and reliability, offering seamless web hosting for Microsoft applications.
Red Hat JBoss EAP offers scalable, easy-to-manage, open-source J2EE capabilities with strong Java integration, ideal for enterprise usage.
It is easy to publish websites with SSL, and it integrates well within the local environment and cloud.
The configurations are simple, making it very easy to use and to set up everything.
Built-in metrics and subsystem isolation, where every subsystem logging, messaging, or web services can be tuned independently, provide fine-grained control over performance and behavior.
It allows for simple modification of applications and provides better clustering capabilities.
JBoss is more flexible and keeps up with modern technologies, supporting newer versions of different libraries.
