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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

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

"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."

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

"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."

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

"Performance-wise, this solution is really good."

More IBM WebSphere Message Broker pros

"The learning curve for this solution is very good."

"The connectors have been the most impactful features for handling integrations. I can use these connectors when I need specific connectivity with a third party, like a core banking system in BFSI. I don't need to do all the development. I take the specific connector, put in the IP address and password, and it takes care of everything."

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

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

"It was mostly easy to set up the product."

"The installation process is easy."

"The solution's technical support is very knowledgeable."

"The customer service executives are very responsive."

More WSO2 Enterprise Integrator pros

Cons

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

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

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

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

"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."

"The installation configuration is quite difficult."

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

"I know that Message Broker was a very tightly copied product with another IBM product, that is, IBM MQ. I would like to have a little bit more decoupling from the IBM MQ because it should not be a prerequisite for IBM WebSphere Message Broker usage."

More IBM WebSphere Message Broker cons

"If I have to buy software, then it becomes expensive for me."

"The administration side is complex and could use significant improvements to enhance the solution's functionality."

"The customization can be a bit difficult."

"The micro integrator should be improved. There is room for enhancement considering alternative integration components."

"You cannot include the validation of XPath."

"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."

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

"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."

More WSO2 Enterprise Integrator cons

Pricing and Cost Advice

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

"The solution is expensive."

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

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

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

"The solution is expensive."

"This product is more expensive than competing products."

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

"It is a low-cost solution."

"The open-source, unsupported version is available free of charge."

"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."

"The cost is better than IBM Cloud Pak."

"The solution costs about 20,000 or 30,000 euros per year, per instance."

"The pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
