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

"I really like SQL integration nodes, HTTP nodes, event handling, event monitoring, the performance of the solution."
"It has the ability to be deployed without rewriting the code."
"The features I have found most valuable in this solution are transformation and routing."
"The integration with other tools is excellent. It integrates well with batch issues."
"The stability is mostly pretty good."
"If you want a platform that seamlessly integrates your different applications, IBM Integration Bus is for you."
"The solution offers good performance and is stable."
"I have found the inbound and outbound adapter confirmations valuable."
"The solution's customer service is good."
"The installation process is easy."
"The productivity is the most valuable feature. It is very easy to write remediations."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"WSO2 Enterprise Integrator may cost you about twenty-five thousand dollars annually per year compared to IBM Cloud Pak, which would cost you around one million dollars."
"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."
"The solution's technical support is very knowledgeable."
"From the capabilities and functional possibility and anything else technical, it is a very well-done product, I have to say."
 

Cons

"The product could be improved by including more resources on SQL and improving the simplicity of the resources available."
"The performance needs to be enhanced when working with the Toolkit."
"The version of the technology and current knowledge is a bit outdated."
"We decided to move away from IBM Integration Bus for IT technical refreshments."
"The solution could improve by having built-in implementation and secure monitoring without the need for API Connect."
"The solution needs to simplify its documentation, such as the user and operation manuals, to make them even easier to understand."
"Stability is mostly fine. However, integration with Oracle is not good."
"They could integrate AI technologies with the product. Additionally, ongoing developments and enhancements in integration technologies could be beneficial."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"We had some challenges with the installation of this solution."
"Most of the issues we run into with the WSO2 Enterprise Integrator deal with customizations."
"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."
"The customization can be a bit difficult."
"You cannot include the validation of XPath."
"The server is very specific and it is very difficult to get experience with it."
"The product's price is an area of concern where improvements are required."
 

Pricing and Cost Advice

"The licensing model of IBM Integration Bus is good. It's a yearly subscription. However, the price is depending on the model that you choose. If it's a Cloud version, then you can pay per month or you can pay it annually upfront. There are three-year options available, but it depends on what deployment you have."
"IBM Integration Bus is expensive."
"It is a highly-priced solution."
"IBM provides a quite complicated licensing model."
"IBM Integration Bus is expensive."
"The solution requires a license and is very expensive here in India."
"The price is reasonable considering the features we receive."
"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."
"It is a low-cost solution."
"The cost is better than IBM Cloud Pak."
"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 pricing of WSO2 Enterprise Integrator for enterprise subscriptions can be considered expensive, especially from the perspective of someone who prefers open-source software."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"The open-source, unsupported version is available free of charge."
