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
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.
Systems Engineer at Atos
Oracle Fusion Middleware is a good product that meets ROI expectations.
Assistant Manager Business Applications at NMC Healthcare
 

Customer Service

Sentiment score
6.5
Users report mixed experiences with Microsoft support, often favoring community resources, but praise premium plan responsiveness.
Sentiment score
6.0
Oracle Fusion Middleware support is effective but needs process efficiency, faster response for non-critical issues, and improved communication.
There are typically no significant issues.
IT System Administrator at Bouri
Microsoft provides a lot of online documentation to consult before speaking to an expert.
Relationship Manager at a financial services firm with 5,001-10,000 employees
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.
Systems Engineer at Atos
Issues are rare, as Oracle generally delivers solutions effectively.
Assistant Manager Business Applications at NMC Healthcare
Customer service for Oracle products, including Oracle Fusion Middleware, is rated at nine points out of ten, indicating it is quite satisfactory.
IT Consultant at a tech vendor with 10,001+ employees
 

Scalability Issues

Sentiment score
7.1
IIS scalability is mixed; effective with clustering and load balancing, but larger scales may need extra infrastructure or cloud migration.
Sentiment score
7.9
Oracle Fusion Middleware is highly scalable, efficient for large users, with potential complexities in virtual machine reliance and management.
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 on-premises deployment, scalability has to be managed manually.
IT Consultant at a tech vendor with 10,001+ employees
 

Stability Issues

Sentiment score
7.8
IIS is praised for enterprise stability, though occasionally challenged by application pool interactions and non-Microsoft technology compatibility.
Sentiment score
7.8
Oracle Fusion Middleware is praised for its stability and improved performance, despite initial deployment challenges and past minor issues.
It was secured for us, as we launched the product, and people were accessing it from India and Virginia, and we had no problem.
Systems Engineer at Atos
I would give it a nine out of ten for stability.
Relationship Manager at a financial services firm with 5,001-10,000 employees
You can check the memory consumption and the number of crashes.
Senior System Integrations Architect at bs-team
Overall, Oracle Fusion Middleware's stability is good.
Assistant Manager Business Applications at NMC Healthcare
 

Room For Improvement

IIS struggles with compatibility, security, usability, and integration issues, inconsistent performance, costly licensing, and limited technical support.
Oracle Fusion Middleware needs UI, integration, and documentation improvements, enhanced support, and cost-effectiveness with containerization and customization flexibility.
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 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
Integrating Copilot could help automate processes or assist in identifying where to make actions or take actions on the server.
Chief Technology Officer at EVtech
Although Oracle provides support, I need the appropriate IT team to adopt these new features.
Assistant Manager Business Applications at NMC Healthcare
The guides often have errors, such as web scripting issues, and can be difficult to follow.
IT Consultant 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 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.
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
Oracle Fusion Middleware is generally expensive, although I'm not directly involved with the licensing aspects.
IT Consultant at a tech vendor with 10,001+ employees
Pricing varies from customer to customer, however, it is reasonable compared to other products in the market.
Assistant Manager Business Applications at NMC Healthcare
 

Valuable Features

IIS offers seamless Microsoft integration, robust management, enhanced security, resource efficiency, user-friendly interface, and robust web hosting support.
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.
IT System Administrator at Bouri
IIS is free.
Senior System Integrations Architect at bs-team
The configurations are simple, making it very easy to use and to set up everything.
Relationship Manager at a financial services firm with 5,001-10,000 employees
Compared to competitors, its cost-effectiveness and Oracle's regular updates every three months are advantageous.

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.

Base installation facilitates quick integration and seamless application deployment in diverse environments
Oracle Fusion Middleware's base installation is ready to use, allowing for quick integration of applications and installation of necessary resources. It offers scalability that is readily available in Oracle Cloud Infrastructure, but requires manual escalation for on-premises setups. Oracle Service Bus provides integration functionality ready for use. Enterprise Manager has also enhanced my experience with its excellent support.
