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 process-oriented solution allows you to define choreography and orchestration."
"The core is very stable."
"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."
"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."
"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 learning curve for this solution is very good."
"The installation process is easy."
"The solution's customer service is good."
"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."
"Currently, I find the configuration part quite valuable, where you can easily configure things."
"The stability is excellent."
"It's a consolidated product. It works and it does its job pretty well."
 

Cons

"The documentation needs to be better."
"Cloud deployment is weak and needs to be improved."
"The documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"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."
"I would like to see them bring back a feature, from earlier versions, that was very useful in debugging and finding issues."
"I would like to see better documentation for the open-source version."
"The setup can be difficult for those not familiar with the solution."
"The administration side is complex and could use significant improvements to enhance the solution's functionality."
"The integration capabilities need to be improved."
"They should introduce better pricing for small companies."
 

Pricing and Cost Advice

"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."
"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."
"The solution costs about 20,000 or 30,000 euros per year, per instance."
"It is a low-cost solution."
"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."
"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 cost is better than IBM Cloud Pak."
