Efficient data transformation and seamless integration drive successful deployments
As for improvements in IBM Integration Bus, we are getting another feature of the retry mechanism now. Version 8.13 was upgraded, and we started using the retry mechanism itself, and we are using nodes in the development level. They are improving one of the nodes such as the HTTP request node, implementing the indirect retry mechanism itself, and we are getting new features.

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

"What I like best are the monitoring features."
"The most valuable features of the IBM Integration Bus are the flexibility to easily integrate with other solutions, such as SAP or any other vendors."
"I recommend it for large enterprises but only for specific use cases. You need to have a relatively mature integration practice in your organization to leverage its capabilities fully."
"I really like SQL integration nodes, HTTP nodes, event handling, event monitoring, the performance of the solution."
"We use IBM Integration Bus for document conversions."
"The error handling and monitoring functionalities of IBM Integration Bus are very good."
"The multi-approach and the multi-capabilities are valuable."
"It is user-friendly and a value-added tool for banks and other verticals."
"The installation process is easy."
"I like the user-friendly system and development of the service-oriented architecture."
"The solution basically conforms to our standards."
"It was mostly easy to set up the product."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
"The learning curve for this solution is very good."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
"WSO2's analytics capability is good, considering the ELC support they provide."
 

Cons

"I would like for them to make the training much easier."
"I would like to be able to run and install this solution on different platforms."
"Current aggregation implementation should be deprecated. MQ independent, as well as an intuitive solution, should be proposed."
"Development toolkit (based on Eclipse) should be improved in terms of responsiveness."
"We have come across many customer complaints about the excessive time it takes for IBM to provide customer and technical support."
"I think security should be more simplified."
"Performance can be an issue sometimes. The tool occasionally crashes due to memory-related problems. We've reported these issues to IBM, and they are actively working on improving the tooling experience."
"Sometimes migration takes too long."
"They should release upgrades more frequently."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"In my opinion, the administration model and interface, of Carbon, are lacking in terms of its features and user experience."
"The server is very specific and it is very difficult to get experience with it."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"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."
"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."
"The integration capabilities need to be improved."
 

Pricing and Cost Advice

"Our licensing is based on a five-year contract, and as far as I know, there are no costs in addition to the standard licensing fee."
"IBM Integration Bus is expensive."
"I generally do not get involved in the licensing or pricing because I'm a hardcore technical guy, but I'm aware of the fact that IBM is highly expensive, so not everybody can afford it. All the products are licensed."
"IBM Integration Bus is expensive."
"The price is reasonable considering the features we receive."
"The solution requires a license and is very expensive here in India."
"As customers, we always try to buy things as cheaply as possible. But the price for the IBM Integration Bus is fine. When we compare it to competitors, it's pretty much the same. However, there are a lot of open-source integration platforms coming to the market as well. So overall, the price is fine as far as licensed products are concerned."
"It is a highly-priced 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."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"It is a low-cost solution."
"The open-source, unsupported version is available free of charge."
"The cost is better than IBM Cloud Pak."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
