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
5.7
Network authentication improved, offering affordability and ROI, though user-friendly enhancements for IIS novices are needed.
Sentiment score
4.9
Red Hat JBoss EAP streamlines deployment, reduces downtime, and cuts costs with scalable, efficient licensing and rapid migration.
It should be more user-friendly overall, because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it.
Systems Engineer at Atos
This flexibility translates to a lower total cost of ownership.
Director of Product at a computer software company with 201-500 employees
For an existing migration project which was stipulated for a timeline of six months, it just took around two and a half months, specifically 80 days.
Senior Software Engineer at a tech vendor with 10,001+ employees
I have observed a return on investment with Red Hat JBoss Enterprise Application Platform (EAP) since the time saved is directly related to the number of incidents that have decreased.

6.8
Red Hat JBoss EAP offers efficient scalability and flexibility, supporting various organizations and handling up to 1,000 users effectively.
Cloud solutions may have better scalability options compared to IIS.
Chief Technology Officer at EVtech
It depends on the server environment and the presence of a UPS for power backup.
IT System Administrator at Bouri
I would rate the scalability of IIS as a six, mainly due to integration issues since it cannot integrate with other environments.
Relationship Manager at a financial services firm with 5,001-10,000 employees
For stateless applications, there is no problem scaling horizontally, and multiple instances of Red Hat JBoss Enterprise Application Platform (EAP) can be deployed.

Sentiment score
7.4
Red Hat JBoss EAP is highly stable, handling heavy loads reliably, outperforming competitors, with minor occasional deployment issues.
I would give it a nine out of ten for stability.
Relationship Manager at a financial services firm with 5,001-10,000 employees

Room For Improvement

IIS struggles with compatibility, security, usability, and integration issues, inconsistent performance, costly licensing, and limited technical support.
Red Hat JBoss EAP needs automation, cloud integration, better documentation, technical support, stability, and modern deployment capabilities.
It's influenced by the server's service performance.
IT System Administrator at Bouri
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.
Relationship Manager at a financial services firm with 5,001-10,000 employees
It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it.
Systems Engineer at Atos
Making it lighter and more modular would probably be beneficial.
Director of Product at a computer software company with 201-500 employees
From a support point of view, whatever support we get from IBM for Red Hat JBoss Enterprise Application Platform (EAP) and for Red Hat, we are fine.

Red Hat JBoss Enterprise Application Platform (EAP) can be improved by integrating different services related to Azure and AWS.
Senior Software Engineer at a tech vendor with 10,001+ employees
 

Setup Cost

Enterprise users find IIS cost-effective within Windows but some see high licensing fees compared to Linux alternatives.
Red Hat JBoss EAP offers cost-effective pricing, flexible licensing, and support, making it competitive against WebLogic and WebSphere.
If you have a Windows license, there is no additional cost for IIS.
IT System Administrator at Bouri
We never had any pricing issue, but I don't know if it is competitive or not.
Systems Engineer at Atos
If we are charging around 0.75 cents per hour for a virtual machine on AWS, then in the Red Hat JBoss orchestrator, charges have seen significant improvement at around 0.58 cents.
Senior Software Engineer at a tech vendor with 10,001+ employees
JBoss is the cheaper option out of the three when compared to WebSphere and WebLogic.
Director of Product at a computer software company with 201-500 employees
The offer includes not only the product but also configuration, deployment, and multiple other services.
IT Advisor at ONVA-RJV
 

Valuable Features

Krishnakumar Natarajan - PeerSpot reviewer
Systems Engineer at Atos
Designs and manages multiple websites while ensuring data backup and disaster recovery
I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.

Migration has reduced incidents and simplifies managing secure hybrid applications
Red Hat JBoss Enterprise Application Platform (EAP) can be improved, as there are changes with the Java version, transitioning from Java to Jakarta since the last JBoss 8 version. I had to make several changes across my server to align with these updates, which was a challenging task for me as it took time. Additionally, in terms of security, there are still some concerns with hacking on Java versions and Java ports, and the XML libraries should be more secure, maintaining consistency to facilitate smoother migrations between versions. My experience during migrations with Red Hat JBoss Enterprise Application Platform (EAP) was mainly smooth, but I encountered application-specific issues because some applications were not compatible with the new version. I had to roll back and troubleshoot these issues, reaching out to Red Hat for assistance, and they were instrumental in resolving those concerns.
