Executive SummaryUpdated on Mar 5, 2025

IBM WebSphere Message Broker and IIS compete in enterprise technology infrastructure, with WebSphere excelling in integration and IIS in web server management. WebSphere holds an advantage in complex integration scenarios, whereas IIS is favored for web hosting efficiency and ease of use.

Features: IBM WebSphere Message Broker facilitates extensive enterprise integration with support for various messaging protocols and IT environments. It offers robust capabilities for complex system connectivity and transformation processes. IIS provides comprehensive web server management, integrating seamlessly with Windows applications. Its user-friendly interface and efficient resource management make it ideal for web-centric deployments.

Room for Improvement: IBM WebSphere Message Broker could improve its initial setup process, offering simpler onboarding for new users. Its pricing model might deter smaller enterprises. Enhanced user interface for streamlined operations would also be beneficial. IIS could strengthen its integration capabilities beyond Microsoft products. Security enhancements could further bolster its reliability. Offering more detailed documentation for advanced configurations would aid less experienced users.

Offers large-sized business information processing with a time-saving setup and impressive stability

I primarily use two previews of the product for Dev and two for QA as part of the production process. Whatever tools our company is using, the cost of a license in IBM WebSphere Message Broker is about 80% of all these software or tools. The message routing capabilities satisfy workflow efficiency. The product supports message formats of XML, JSON, and SSID, which are around 24 KB to 50 KB in size. The solution supports communication protocols like STTP and TCP. Features like DataGraph need to be introduced in IBM WebSphere Message Broker. Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore. For the aforementioned version, our company professionals can solve the queries on their own without seeking support from IBM. During the installation of a prior version of IBM WebSphere Message Broker, sometimes I have to configure the failovers through the cluster, where issues arise, and I often seek help from the support team. The solution is being used by some medicine companies in our organization that receive sales orders from the EDR or JDE. I would not recommend the product to others as its becoming obsolete and they can rather choose a middleware solution from Amazon or Azure. But I would overall rate the product a nine out of ten.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It has many interfaces and you can connect to any backend source that has another format, and convert it to the desired format."

"The solution has good integration."

"Straightforward development and deployment."

"It is a scalable solution...The setup is easy."

"The most valuable feature of IBM WebSphere Message Broker is the ability to facilitate communication with legacy systems, offering a multitude of great capabilities. For example, if there is a mainframe system in place with a web service serving as the front end. In that case, the solution enables efficient protocol transformations to convert all request payloads into a format that the legacy systems can accept, rendering the integration and transformation processes seamless and highly effective."

"Integration and mapping are easy, which is a major advantage."

"The transactions and message queuing are the most valuable features of the solution."

"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."

More IBM WebSphere Message Broker pros

"The tool shows us the operating systems where our servers and applications are running."

"It's good and offers good usability."

"The most valuable feature of IIS is the database it provides."

"IIS works natively with Windows Server without any issues in publishing certificates."

"Stability-wise, I rate the solution a nine out of ten...Scalability-wise, I rate the solution a nine out of ten."

"The solution is easy to use, easy to maintain and isn't too technical."

"My experience with the technical support by Microsoft at large is satisfactory."

"The solution is very stable. The solution is very simple and easy to use."

More IIS pros

Cons

"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."

"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."

"Technical support is good but they could have a better response time."

"The images and size of the containers are too big and I think that they should be more lightweight."

"The product's features are not being upgraded or enhanced by the vendor"

"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."

"It is currently a weighty product."

"Stability and pricing are areas with shortcomings that need improvement."

More IBM WebSphere Message Broker cons

"Having no support for other than a Microsoft environment and programming languages limits the usage of IIS in many cases."

"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."

"I see that IIS has maintained the same interface for a long time, so they could potentially use more automation or integrate Copilot into it to make it easier to use."

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

"There is an issue with the network. The tool's price is also high."

"IIS's memory management could be improved."

"The level of technical support the solution offers could be improved."

"The documentation is not very detailed. They need to improve it and add to it. They should ensure there are lots of visuals to help users better understand the solution."

More IIS cons

Pricing and Cost Advice

"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."

"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."

"The solution is expensive."

"IBM products are generally more stable and have more features, but also come at a greater cost."

"The price is very high and it's the main reason that we are searching for alternatives."

"This product is more expensive than competing products."

"The licensing cost of IBM WebSphere Message Broker needs to be reduced"

"The solution is expensive."

"IIS's pricing is not expensive."

"IIS's pricing is reasonable."

"I give the price of the solution a five out of ten."

"The product's price is not high."

"They offer a one-time payment model for the product license, and we pay annually for support."

"The solution’s pricing is yearly. The pricing is affordable and not high."

"Users can get a subscription-based license or a perpetual license for IIS."

"There is a license needed for the solution."
