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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

Effective data transformation and integration in complex environments with high functionality

Something that could be improved in WSO2 Enterprise Integrator is that the problem is not a lack of capability or functionalities. The problem is that it is a very complex environment. To put your hand on this environment is a very demanding task. This is the real problem. The problem is not about the product, but about the complexity to manage, to configure, to decide what to do. I have some experience using SAP R/3. It seems to me something similar. When you have to configure a situation with a client, especially for a client not in an industrial sector, but in a service sector, it is quite usual that you are in trouble for some reason. This is always the story that I found in the implementations I have done. Maybe there are only three or four big problems, in some other cases there are more than that, but this is the situation usually. For WSO2 Enterprise Integrator, not the same, but I must say it is quite often there is a need to put together some pieces and make it work in a coordinated way.

Quotes from Members

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

Pros

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

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

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

"The solution has good integration."

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

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

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

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

More IBM WebSphere Message Broker pros

"The solution's customer service is good."

"It's a very complete product. It allows us to network security and add more layers of security to the system."

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

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

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

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

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

"The customer service executives are very responsive."

More WSO2 Enterprise Integrator pros

Cons

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

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

"Technical support is very slow and needs to be improved."

"The installation configuration is quite difficult."

"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."

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

"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."

More IBM WebSphere Message Broker cons

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

"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."

"They should introduce better pricing for small companies."

"The integration capabilities need to be improved."

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

"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."

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

"They should release upgrades more frequently."

More WSO2 Enterprise Integrator cons

Pricing and Cost Advice

"The solution is expensive."

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

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

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

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

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

"This product is more expensive than competing products."

"The solution is expensive."

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

"It is a low-cost solution."

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

"The cost is better than IBM Cloud Pak."

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