Helpful for complex integrations because it has tools and functionality to integrate with other systems
Everything needs to be improved. As far as integration and the cloud are concerned, things are moving to the cloud side. When you use Kubernetes and similar technologies, IBM Integration Bus doesn't greatly facilitate these environments. Maybe I don't know enough about that, but I feel that when it comes to the DevOps environment, the tool needs to be deployed on production in a way that's just like pods. Cloud integration needs to be more facilitated with the DevOps environment. This IBM technology needs to adapt because in the recent world, in the real world, we see that everything is just a cloud pod. Whenever you need to scale anything, you just put some cloud and pod and improve it, make any server and deploy it. But in IBM Integration Bus, there is a problem because we can't do this as easily. In short, IBM needs to more emphasize or more integrate with the cloud environments as well, similar to DevOps. There are limitations in IBM Integration Bus when it comes to DevOps.

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

"The most valuable feature is that it is clear and easy to learn."
"The interface is quite stable."
"IBM Integration Bus is a very strong tool."
"We use IBM Integration Bus for document conversions."
"Content is easily infiltrated in the eclipse infrastructure."
"I really like SQL integration nodes, HTTP nodes, event handling, event monitoring, the performance of the solution."
"It is user-friendly and a value-added tool for banks and other verticals."
"IBM Integration Bus has a complete set of tools that are implemented between rules when it comes to run time, but it's not easy to understand."
"I like the user-friendly system and development of the service-oriented architecture."
"The installation process is easy."
"The productivity is the most valuable feature. It is very easy to write remediations."
"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 stability is excellent."
"The drag-and-drop features for connectors are very valuable."
"The learning curve for this solution is very good."
"The customer service executives are very responsive."
 

Cons

"They could integrate AI technologies with the product. Additionally, ongoing developments and enhancements in integration technologies could be beneficial."
"The cloud deployment of the IBM Integration Bus should be made easier."
"They need to come up with Integration Platform as a Service (iPaaS). It should also have a feature for integrating with those applications that are on the cloud."
"IBM could improve its connectivity."
"IBM does not support orchestration, which is how they designed it, and other BPM tools in the market support orchestration. If they merged the BPM capability into this product, then it would be a better solution."
"Licensing is too high. It is quite expensive."
"I would rate the support from IBM Integration Bus a seven out of ten. They are very helpful but sometimes it takes too long for them to respond."
"In terms of improvement, the UI should be more user-friendly."
"They should release upgrades more frequently."
"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 server is very specific and it is very difficult to get experience with it."
"They should introduce better pricing for small companies."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"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 product's price is an area of concern where improvements are required."
"You cannot include the validation of XPath."
 

Pricing and Cost Advice

"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."
"The price is reasonable considering the features we receive."
"It is a highly-priced solution."
"IBM Integration Bus is expensive."
"IBM Integration Bus itself is prices fair but App-Connect is a bit expensive which we use in conjunction with it."
"For small companies, First of all, there are a lot of free products that could be used for integration. It can use the cloud or new implementation in the past. But if the tool is IBM, the official box in your company, you can make your submission and also publish the cloud to the work file. But let’s say, if you are working with premises, then you have to buy a reasonable main full support and gain experience with your product."
"The price of this product could be lower."
"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."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"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 open-source, unsupported version is available free of charge."
