Oracle Fusion Middleware is highly scalable, efficient for large users, with potential complexities in virtual machine reliance and management.

Oracle WebLogic Server is scalable, suitable for large datasets; challenges may arise with configurations, but offers high ratings.
It depends on the server environment and the presence of a UPS for power backup.
I would rate the scalability of IIS as a six, mainly due to integration issues since it cannot integrate with other environments.
For on-premises deployment, scalability has to be managed manually.
I find Oracle WebLogic Server to be highly scalable, rating it as nine out of ten.

Room For Improvement

IIS faces compatibility, setup, monitoring, and cost issues, needing enhancements in scalability, security, UI, and open-source support.
Oracle Fusion Middleware needs UI, integration, and documentation improvements, enhanced support, and cost-effectiveness with containerization and customization flexibility.
Oracle WebLogic Server needs better integration, microservices support, stability, memory management, customer support, and simpler configurations.
It's influenced by the server's service performance.
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.
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.
Using scripting allows for the creation of resources.
 

Setup Cost

Enterprise buyers find IIS cost-effective with Windows Server, appreciating licensing flexibility despite some complaints about overall expense.
Oracle Fusion Middleware is costly, suited for large organizations; starting small and expanding recommended due to accumulating annual costs.
Oracle WebLogic Server's per-core pricing can be costly, especially compared to free alternatives like JBoss or Tomcat.
If you have a Windows license, there is no additional cost for IIS.
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 valued for its integration, security, and reliability, offering seamless web hosting for Microsoft applications.
Oracle Fusion Middleware offers scalable, flexible integration with advanced AI features, seamless connectivity, and compatibility within Oracle's ecosystem.
Oracle WebLogic Server provides robust features like scalability, security, and reliability, making it ideal for enterprise applications.
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.
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.
It also offers cluster services, which means I can install, create clusters, and add WebLogic Servers as members.

Provides integration with Eggplant but problems with stability
We use Windows Server only for Eggplant Manager. Otherwise, I'm not using it   At the moment, we have big problems with stability, and I'm not very happy at the moment. So, the stability could be improved. I have been using it for a few years.  The initial setup is complex.  We have an…

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.
Saikat Nag - PeerSpot reviewer
Offers efficient load distribution with a scope of high scalability
Our organization configures Oracle WebLogic Server in such a way that a load balancer becomes available. The network requests are segregated to the Oracle WebLogic Server as the managing server and different nodes are configured. Using the product as a load balancer helps automate request transfer from one non-functional node to another functional node. Due to Oracle WebLogic Server, the endpoints remain unaffected whenever a node goes down. The clustering feature enhances our organization's performance and reliability. In our organization, the health of the Oracle WebLogic Server environment is maintained and managed using Oracle Enterprise Manager (OEM). I would definitely recommend others to use Oracle WebLogic Server. Overall, I would rate the solution an eight out of ten.
