Efficient integration across varied systems through advanced routing and enrichment services

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

"Monitoring feature that allows tracking of the web's UI development."
"Service Bus is good at routing the transformation."
"It is lightweight and one can easily integrate with different applications, databases, JMS, or web services through different protocols."
"The ability to master the process in one location."
"API management and defining varying protocols are the most valuable features"
"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."
"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."
"It is stable."
"The solution basically conforms to our standards."
"I like the user-friendly system and development of the service-oriented architecture."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"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 customer service executives are very responsive."
"The installation process is easy."
"It's a consolidated product. It works and it does its job pretty well."
"WSO2's analytics capability is good, considering the ELC support they provide."
 

Cons

"The support for GraphQL needs to be improved, and the response time for global support could be faster."
"There are issues, especially if you want to create some compensation in your service bin."
"The connectivity with the solution is an area that needs to be improved. On occasion, requests are lost due to losing connectivity."
"What needs improvement in Oracle Service Bus is the connectivity between adapters such as the Salesforce adapter and database adapters. The limited number of adapters compatible with Oracle Service Bus makes you want to switch to a different solution."
"It's very complex and hard to learn. There's a steep learning curve."
"There are times when I select components in composite and they do not appear, and I cannot figure out why."
"An area for improvement in Oracle Service Bus is the roadmap for its product launch. Currently, it's unclear, so Oracle should develop a roadmap for version 12c, so people can see what's coming out of that version of Oracle Service Bus. Cloud hosting is an additional feature I'd like to see in the next release of Oracle Service Bus."
"The inconvenient part about working with this product is that it's very heavy, requiring a lot of people and a lot of resources."
"I would like to see better documentation for the open-source version."
"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."
"WSO2 libraries are not mature enough. For example, if you want to integrate with Kafka using its Kafka library, it often has many bugs."
"The server is very specific and it is very difficult to get experience with it."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"The micro integrator should be improved. There is room for enhancement considering alternative integration components."
"If I have to buy software, then it becomes expensive for me."
"The setup can be difficult for those not familiar with the solution."
 

Pricing and Cost Advice

"Oracle Service Bus is a bit expensive"
"We have an unlimited yearly license."
"I'm not aware of how much Oracle Service Bus costs."
"The pricing is on the higher side."
"The price of this solution is better than the subscription-based Mule ESB."
"This is a very expensive product and the price varies depending on factors such as the number of processors and the number of users. Our licensing fees are approximately $300,000."
"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."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
