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
If application performance monitoring tools were already part of the management console at runtime, it would be very helpful.
CIO at Clayfin
Easier upgrade migration tooling for enterprise applications can also be provided, alongside better dashboards and more modern observability and monitoring integration.
Senior software developer at Simplifyvms
This approach makes it easier to develop, deploy, and administer applications.
Head of International Institutional Marketing at Natixis
 

Setup Cost

Enterprise users find IIS cost-effective within Windows but some see high licensing fees compared to Linux alternatives.
JBoss EAP offers competitive subscription pricing and robust support, ideal for large enterprises but costly for smaller firms.
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
The price from a local provider was approximately $64,000.
President/ Owner at Asvesot C.A.
There were challenges as costs can significantly rise at larger scales, making it more expensive than alternatives such as Apache Tomcat, which was a lightweight container solution.
Senior software developer at Simplifyvms
This allowed me to spin up the pre-configured licensed instance on RHEL immediately while consolidating all licensing costs into my unified AWS cloud infrastructure bill.
System engineer at a retailer with 10,001+ employees

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.
Pranay Jain - PeerSpot reviewer
Senior software developer at Simplifyvms
Centralized management has improved enterprise Java workflows and simplified transaction handling
The best feature that stands out is the strong support for Enterprise Java workloads, along with high stability and transaction management. It provides stability for the services to get deployed, and we can easily manage the transactions that happen via the REST APIs, which is great in that regard. It also provides centralized application management, so if an application is deployed and needs to be used through multiple places, centralized application deployment management is possible. The centralized management clustering capability is very useful for high availability enterprise deployment. This centralized application management is beneficial because the application, the search service we have written in Java, has simplified deployment, and operational control across environments is also easy. It helps our team since it has centralized deployment management, allowing applications to be deployed and updated from a centralized CLI or console, which reduces manual server-by-server management and improves deployment consistency. It also provides easier monitoring and troubleshooting, which is excellent; if an issue occurs, such as the search service failing, we could quickly identify which node or deployment was affected instead of manually checking multiple servers. This has definitely given us positive feedback; that is why we have been using it for around 1.5 years, and it is still coping with our applications. The impact is that application stability has improved quite a bit, and deployment consistency allows us to deploy, update, restart, and check the logs all at once without checking multiple servers, along with improved operational management for Enterprise Java services.
