Executive SummaryUpdated on Feb 2, 2025

Oracle WebLogic Server and Microsoft IIS are prominent competitors in enterprise application platforms. WebLogic Server stands out for complex enterprise environments, offering strong integration with Oracle products, while IIS is favored for its seamless integration with Microsoft systems, making it ideal for smaller applications and Windows users.

Features: Oracle WebLogic Server offers a comprehensive administration console, robust clustering capabilities, and seamless integration with Oracle products, making it suitable for complex enterprise needs. IIS provides easy integration with Microsoft systems, simplicity, and a lightweight configuration, ideal for smaller applications and users in a Windows environment.

Room for Improvement: Oracle WebLogic Server could improve by offering a lighter version for microservices, addressing configuration challenges, and revising costly licensing terms. Enhancements in monitoring, diagnostics, and pricing are also desirable. IIS users seek better integration with non-Microsoft products, enhanced security features, and simpler setup procedures.

Ease of Deployment and Customer Service: Oracle WebLogic Server, often deployed in on-premises and hybrid settings, benefits from 24/7 support but at a high cost. Its support quality varies but is generally effective. IIS, primarily on-premises with cloud capabilities, offers straightforward deployment due to its Windows integration, though its support outside Microsoft systems can be improved.

Pricing and ROI: Oracle WebLogic Server involves a high initial cost due to licensing based on physical cores, contributing to substantial expenses but providing strong ROI through its robust capabilities. IIS is cost-effective, included with Windows Server licenses, offering a budget-friendly choice for smaller businesses or those invested in Microsoft systems, with reasonable ROI in compatible environments.

Network authentication improved, offering affordability and ROI, though user-friendly enhancements for IIS novices are needed.

Sentiment score

6.3

Oracle WebLogic Server offers significant long-term benefits with enterprise features, enhancing performance, compliance, and operational efficiency despite high costs.

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.

7.5

Oracle WebLogic Server is highly rated for scalability, effectively managing large datasets and high user loads across settings.

Cloud solutions may have better scalability options compared to IIS.

Juan Pablo Lauterio

Chief Technology Officer at EVtech

I would rate the scalability of IIS as a six, mainly due to integration issues since it cannot integrate with other environments.

reviewer1256511

Relationship Manager at a financial services firm with 5,001-10,000 employees

It depends on the server environment and the presence of a UPS for power backup.

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.

It's influenced by the server's service performance.

Ibrahim Sherif

IT System Administrator at Bouri

Integrating Copilot could help automate processes or assist in identifying where to make actions or take actions on the server.

Juan Pablo Lauterio

Chief Technology Officer at EVtech

It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it.

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.

If you have a Windows license, there is no additional cost for IIS.

Ibrahim Sherif

IT System Administrator at Bouri

We never had any pricing issue, but I don't know if it is competitive or not.

Krishnakumar Natarajan

Systems Engineer at Atos

For more quotes and insights, download the IIS report

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.

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.
