Sentiment score
4.7
Red Hat JBoss EAP offers cost-effective, scalable solutions with automation and customization, reducing costs and accelerating project completion.
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.

I would rate the scalability of IIS as a six, mainly due to integration issues since it cannot integrate with other environments.

7.8
IIS is praised for enterprise stability, though occasionally challenged by application pool interactions and non-Microsoft technology compatibility.

7.4
Red Hat JBoss EAP is highly reliable and stable, notably outperforming IBM and Oracle WebLogic in production environments.
I would give it a nine out of ten for stability.

It is quite stable for our needs.
VP at a financial services firm with 10,001+ 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 customization, better integration, modern tech support, improved pricing, faster support, and enhanced documentation.
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 offers cost-effective, flexible open-source solutions with comprehensive support, especially advantageous in cloud environments.
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 price is somewhat high for an enterprise, however, it depends on organizational negotiations.
VP at a financial services firm with 10,001+ employees

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.

Rapid deployments have streamlined containerized web apps but support response still needs improvement
The best features Red Hat JBoss Enterprise Application Platform (EAP) offers are its integration into AWS services, which is very helpful in containerization and application of Kubernetes specifically, and its user interface is very easy to use; we can deploy WAR files within stipulated time and also schedule deployments at a particular time, and it is easy to run the pipelines and integrate it with Jenkins. The most valuable feature for my team is containerization and Jenkins integration because Jenkins integration helps us eradicate code smells and build pipeline reports, and it also supports continuous CI/CD pipelining, while this orchestration aids in a microservice architecture where we will be using different types for it. Red Hat JBoss Enterprise Application Platform (EAP) has positively impacted my organization by helping in quickly making web Spring Boot applications and Java-based applications, and it is very easy to adapt and learn, plus it is open source with nominal and affordable subscription plans.
