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

"The solution has enhanced data processing capabilities by allowing efficient data integration and transformation."
"The most valuable feature is the security."
"We've been using IBM Integration Bus for seven years to create a service-oriented architecture in our bank and implement SOAR infrastructure using this tool. It helps us with internal services for core banking and different digital channels. We also use it to expose our services to other banks and companies and consume services from outside our bank using proxy servers."
"Earlier, it was only possible to have an on-premises installation, but now that it's compatible with the cloud, it's a very seamless and fantastic tool."
"Easy to understand documentation with a huge list of examples and tutorials."
"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."
"There are three elements that make IBM Integration Bus very important for our organization's payroll systems which are the solution's high scalability, performance, and reliability."
"The cost is pretty cheap, compared to what else is available in the market."
"While I am still exploring the solution, I've so far been pretty satisfied with it."
"The solution's technical support is very knowledgeable."
"In my opinion, the most valuable aspect of this solution is its extensive range of adaptors and connectors. This feature holds significant importance and provides great value to users."
"The solution basically conforms to our standards."
"The most valuable aspect of the solution is the integration between core banking and other systems."
"The solution's customer service is good."
"The installation process is easy."
"It was mostly easy to set up the product."
 

Cons

"The product lacks an integrated testing module."
"Current aggregation implementation should be deprecated. MQ independent, as well as an intuitive solution, should be proposed."
"I would like to see more metered rest and API support. IBM is already working on it on Version 11, but it still needs improvement."
"Its integration with Cloud Pak components could be better."
"It would be better with more API management features. More micro-service and container-based support."
"The product does not provide API management."
"Some of the runtime properties need to be improved because if you want to load certificates as sales security, you have to restart the server."
"Storage capacity of the product should be addressed."
"The configuration of the product is not an easy task for everyone."
"They should introduce better pricing for small companies."
"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."
"The product's price is an area of concern where improvements are required."
"I would like to see better documentation for the open-source version."
"The customization can be a bit difficult."
"For simpler tasks or simpler use cases, we avoid using WSO2 Enterprise Integrator because it is quite complex."
 

Pricing and Cost Advice

"It is not cheap. It has its cost. It is one of the high-cost solutions."
"IBM Integration Bus is expensive."
"The price of this product could be lower."
"Pricing is on par with its competition."
"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."
"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."
"Support costs are high compared to the competition. Otherwise, the support is good."
"The maintenance and support of the product are very expensive."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"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."
"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."
