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.

Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.

Quotes from Members

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

Pros

"IBM Integration Bus has been effective in facilitating our messaging and service-oriented architecture (SOA) or bus architecture. So, we're already utilizing it to transform the data from the source it's sending. It converts the data from the format the source sends it into the format the destination system requires. So we are transforming the messages, which are required by the destination system; that's the one way."
"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."
"If people have good knowledge of it, they can really do a lot of stuff."
"The biggest advantage of this solution is that it is very easy to learn, and very easy to build applications."
"IBM Integration Bus is a very good solution and they have come a long way with improvements over the years."
"The message queue connectors are the most valuable feature. They have built-in connectors for most of the systems, like SAP and Oracle Database."
"If you want a platform that seamlessly integrates your different applications, IBM Integration Bus is for you."
"It's stable across multiple platforms and across multiple applications."
"Performance-wise, this solution is really good."
"We have a large number of use cases for this product, and it is built into the underlying infrastructure for most of our applications."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"The solution has good integration."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
"The documentation, performance, stability and scalability of the tool are valuable."
"The most valuable feature of IBM WebSphere Message Broker is the ability to facilitate communication with legacy systems, offering a multitude of great capabilities. For example, if there is a mainframe system in place with a web service serving as the front end. In that case, the solution enables efficient protocol transformations to convert all request payloads into a format that the legacy systems can accept, rendering the integration and transformation processes seamless and highly effective."
 

Cons

"Kafka is much faster. The performance is much greater than IIB. IIB is not as fast as Kafka."
"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."
"The resources about IBM are hard to find, and it is not enough material."
"The solution’s pricing could be improved."
"I don't mind the pricing."
"Licensing is too high. It is quite expensive."
"The memory footprint needs to be improved; having this solution on-prem is taking more memory and that memory footprint should be minimized."
"Development toolkit (based on Eclipse) should be improved in terms of responsiveness."
"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 user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"The solution can add container engines such as docker."
"The product's features are not being upgraded or enhanced by the vendor"
"Technical support is good but they could have a better response time."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
 

Pricing and Cost Advice

"The price of the IBM Integration Bus is expensive. If you compare the price to the cloud version you can purchase what you need but the on-premise version price is flat."
"The pricing of the solution is high."
"The maintenance and support of the product are very expensive."
"IBM Integration Bus itself is prices fair but App-Connect is a bit expensive which we use in conjunction with it."
"IBM provides a quite complicated licensing model."
"IBM Integration Bus solution is expensive and this is one of the reasons we are looking for an alternative, such as MuleSoft."
"The pricing could be improved to make it more competitive."
"IBM Integration Bus is expensive."
"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."
"The solution is expensive."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"The price is very high and it's the main reason that we are searching for alternatives."
"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."
