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 am a part of the software developing team and I mainly use this solution for the integrating applications."
"The stability is consistently high, with only one notable issue encountered."
"It is stable."
"The flexibility offered by Oracle Service Bus, especially in the latest versions, includes abstracting underlying processes and enabling drag-and-drop mappings from source to destination."
"What I found most valuable in Oracle Service Bus is its time to market. It's excellent."
"Its ease of use is valuable. It's very easy to use. It's no code/low code. Oracle Middleware products are also rich in adapters."
"I like the ease of deployment and the ease of implementation."
"Overall it is a pretty good solution."
"The solution's technical support is very knowledgeable."
"I like the user-friendly system and development of the service-oriented architecture."
"It's a consolidated product. It works and it does its job pretty well."
"The customer service executives are very responsive."
"The solution has two main parts: integration and transformation. It's very user-friendly and easy to understand for everyone."
"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 drag-and-drop features for connectors are very valuable."
"It's a very complete product. It allows us to network security and add more layers of security to the system."
 

Cons

"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"It's very complex and hard to learn. There's a steep learning curve."
"Security features can be improved to better protect the server."
"The support for GraphQL needs to be improved, and the response time for global support could be faster."
"We have faced a problem with the heap memory side, but that is stable now."
"The weak point of OSB is the single point of failure."
"The consolidation functionality is minimal, lacking advanced features for complex integrations."
"The pricing of the product could be better. It's a bit high."
"I would like to see better documentation for the open-source version."
"They should release upgrades more frequently."
"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."
"If I have to buy software, then it becomes expensive for me."
"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."
"They should introduce better pricing for small companies."
"The server is very specific and it is very difficult to get experience with it."
