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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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

More WSO2 Enterprise Integrator pros

Cons

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

"They are expensive and not worth the money we are spending on them."

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

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

"I find the installation configuration is quite difficult compared to other solutions."

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

"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."

More IBM WebSphere Message Broker cons

"They should release upgrades more frequently."

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

"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."

"The setup can be difficult for those not familiar with the solution."

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

"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."

"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."

More WSO2 Enterprise Integrator cons

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

"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."

"It is a low-cost solution."

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