Room For Improvement

IIS struggles with compatibility, security, usability, and integration issues, inconsistent performance, costly licensing, and limited technical support.
Oracle WebLogic Server needs performance, pricing, support, and integration improvements, along with enhanced diagnostics and containerization features.
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.

IT Consultant at a tech vendor with 10,001+ employees
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.
Senior Manager, MW & DB Automation at a computer software company with 11-50 employees
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.
Oracle WebLogic Server pricing is per-core, higher for advanced features, but competitive among commercial servers.
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
We are working with an embedded license; for us, it is acceptable, but in reality, the open full license will be costly because it is a number-of-core-based licensing.
Regional Head And Director Product Development at Neptune Software Group
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.

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.

Stable and scalable enterprise deployment with Cloud-Native support
Oracle WebLogic Server helps with my deployment strategy in both monolithic as well as Cloud-Native ways. I think it is useful; this Cloud-Native support helps with deployment in both on-prem and cloud. For container deployment, we are not very rich. We are in the process of moving our business logic to containerization. But in terms of this being a big product, a core banking system, I prefer on-prem rather than cloud. The use cases and the scrum help me a lot in an iterative, incremental manner. I would recommend this product; it is an enterprise, large volume, and of course, it is worth it to deploy. I am providing this review with a rating of 9.

Modernization project has reduced costs and supports high‑transaction Java applications
I love using Red Hat JBoss Enterprise Application Platform (EAP) because it supports enterprise-grade features such as high availability clustering, distributed caching, messaging, and many more. Red Hat JBoss Enterprise Application Platform (EAP) offers excellent features including MOD cluster integration, enterprise-grade feature support, and deployment options on-premises, virtual, and hybrid cloud environments, making it very flexible. MOD cluster integration in Red Hat JBoss Enterprise Application Platform (EAP) has specifically helped my team because JBoss integrates very well with it, serving as an intelligent load balancer that is especially useful in high-clustered environments. Using Red Hat JBoss Enterprise Application Platform (EAP) positively impacts my organization mainly by providing a tool that ensures my system is stable, with no downtime noticed. It is very scalable, handling my organization's growth well, and has fast deployment, which saves a lot of time. Since adopting Red Hat JBoss Enterprise Application Platform (EAP), I have seen it be a game changer, especially in reducing cost, with a cost reduction of about 50%, from 80% to 50%.
