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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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.

Decreases the development timeframe and costs

The main issue with the product is pricing. It uses core-based pricing for WSO2 Enterprise Integrator and API Manager. It would be best if you had APIM by default. It provides many connectors for easy integration with third-party systems. Often, customers decide to develop using open-source tools like Spring Boot if there aren't many connectors required to avoid increasing costs. They'll develop this way and then deploy using APIM, the bare minimum needed. It is mainly required for very complicated setups with many connectors. In the implementations I've seen, people often used open-source tools because there weren't many third-party systems involved—just their organization's own systems. From WSO2 Enterprise Integrator, I expect them to bring up more and more connectors in the future. That's the main expectation. Having more connectors in various areas will help us when discussing new requirements. I don't have any specific use case right now, so I can't name a particular connector. But, as new technologies emerge, the relevant connectors should be there for those. WSO2 Enterprise Integrator mainly helps with the integration part, which can be simplified only if you have relevant connectors for whatever you're doing.

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."

"Straightforward development and deployment."

"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."

"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."

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

"The documentation, performance, stability and scalability of the tool are valuable."

"Message Broker is valuable because most of the applications are using MQ. Even in my current engagement, the few applications which I audit to onboard the bank are using MQ."

More IBM WebSphere Message Broker pros

"Currently, I find the configuration part quite valuable, where you can easily configure things."

"The installation process is easy."

"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."

"The solution's customer service is good."

"It's a consolidated product. It works and it does its job pretty well."

"The drag-and-drop features for connectors are very valuable."

"WSO2's analytics capability is good, considering the ELC support they provide."

"I like the user-friendly system and development of the service-oriented architecture."

Cons

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

"The solution can add container engines such as docker."

"The installation configuration is quite difficult."

"It is currently a weighty product."

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

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

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

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

More IBM WebSphere Message Broker cons

"The product's price is an area of concern where improvements are required."

"They should introduce better pricing for small companies."

"There are a lot of security settings that when you apply you have to re-apply again every time you modify a setting. It is something that really needs to be enhanced."

"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."

"The server is very specific and it is very difficult to get experience with it."

"You cannot include the validation of XPath."

"One of the reasons that we are looking for a replacement is their way of defining integration. The language of the XML structures that I use to describe the integrations are not that standard, and it's not easy to find people who are familiar with this approach."

"I would like to see better documentation for the open-source version."

"The solution is expensive."

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

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

"The solution is expensive."

"This product is more expensive than competing products."

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