Executive SummaryUpdated on Feb 2, 2025

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
6.5
IIS offers positive ROI with authentication benefits, affordability, and security, though user-friendly improvements are suggested for accessibility.
Sentiment score
6.2
Oracle Fusion Middleware offers significant ROI, with some organizations saving 20% by prioritizing essential security investments and assessments.
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.
Oracle Fusion Middleware is a good product that meets ROI expectations.
 

Customer Service

Sentiment score
6.4
Microsoft support gets mixed reviews; praised for efficiency and resources, but criticized for slow response and entry-level understanding.
Sentiment score
6.0
Oracle Fusion Middleware support is effective but needs process efficiency, faster response for non-critical issues, and improved communication.
Microsoft provides a lot of online documentation to consult before speaking to an expert.
There are typically no significant issues.
I would rate the support from Microsoft very high because I definitely got all the help during the testing time of the development kit while we were configuring features on our on-premises server.
Issues are rare, as Oracle generally delivers solutions effectively.
Customer service for Oracle products, including Oracle Fusion Middleware, is rated at nine points out of ten, indicating it is quite satisfactory.
 

Scalability Issues

Sentiment score
7.1
IIS is scalable for varied applications, though dependent on hardware, with improvements in clustering and flexible service management.
Sentiment score
7.9
Oracle Fusion Middleware is highly scalable, efficient for large users, with potential complexities in virtual machine reliance and management.
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.
For on-premises deployment, scalability has to be managed manually.
 

Stability Issues

Sentiment score
7.8
IIS is stable and reliable, excelling with .NET but facing stability issues with non-Microsoft technologies. Rated 7-9/10.
Sentiment score
7.8
Oracle Fusion Middleware is praised for its stability and improved performance, despite initial deployment challenges and past minor issues.
I would give it a nine out of ten for stability.
It was secured for us, as we launched the product, and people were accessing it from India and Virginia, and we had no problem.
I would rate IIS's stability as an eight out of ten.
Overall, Oracle Fusion Middleware's stability is good.
 

Room For Improvement

IIS struggles with compatibility, user-friendliness, integration, performance, security, and documentation challenges, posing significant user and scalability issues.
Oracle Fusion Middleware needs UI, integration, and documentation improvements, enhanced support, and cost-effectiveness with containerization and customization flexibility.
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 should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it.
It's influenced by the server's service performance.
The guides often have errors, such as web scripting issues, and can be difficult to follow.
Although Oracle provides support, I need the appropriate IT team to adopt these new features.
 

Setup Cost

IIS licensing is bundled with Windows Server, offering flexible options but may incur extra costs for services and fees.
Oracle Fusion Middleware is costly, suited for large organizations; starting small and expanding recommended due to accumulating annual costs.
If you have a Windows license, there is no additional cost for IIS.
We never had any pricing issue, but I don't know if it is competitive or not.
Oracle Fusion Middleware is generally expensive, although I'm not directly involved with the licensing aspects.
Pricing varies from customer to customer, however, it is reasonable compared to other products in the market.
 

Valuable Features

IIS is user-friendly, efficient, secure, and integrates well with Microsoft, offering scalability and control for IT administrators.
Oracle Fusion Middleware offers scalable, flexible integration with advanced AI features, seamless connectivity, and compatibility within Oracle's ecosystem.
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.
The best features of IIS are that you can design your own website and manage it yourself, creating as many websites as you want.
Oracle recommends moving to Oracle Fusion as they are constantly releasing new AI, modern, web-based, and cloud-based features with updated UI.
Oracle Fusion Middleware's base installation is ready to use, allowing for quick integration of applications and installation of necessary resources.

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.
Sai Kri - PeerSpot reviewer
Migration to a modern interface enhances AI integration and cloud capabilities
Presently, Oracle recommends migrating to Oracle Fusion since it's a hot product now. e-Business Suite may soon be sunsetted and has an outdated UI, with few upgrades. In contrast, Oracle Fusion offers modern features, such as AI, cloud-based applications, and customization options like Redwood features. Oracle Fusion AI chatbots are embedded, benefiting projects.
