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."

"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."

"The core is very stable."

"The messaging part is the most valuable feature."

"The most valuable feature of webMethods Integration Server is all the capabilities it provides. We leverage most of the features, that they have offered to us. Our vendor has made some additional features on top of the webMethods Integration Server and we use all the features together."

"High throughput and excellent scalability."

"We have a reusable code that we can replicate for any new interfaces."

"The tool is very powerful and user-friendly."

"Given that you have one integration API in place, it takes very minimal effort to scale it to any other application that might want to use the same. Its flow-based development environment is a breeze and makes it really easy to re-use most of the existing components and build up a new API."

"The product supports various types of digital documents, including XMLs and EDI."

"The developer portal is a valuable feature."

Cons

"The documentation needs to be better."

"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."

"Cloud deployment is weak and needs to be improved."

"Support is expensive."

"On the monitoring side of things, the UI for monitoring could be improved. It's a bit cumbersome to work with."

"Some of the things that we use cannot be done in this solution. For these things, we have to either use a Java service or a util service. There is no predefined or existing service that we can use. So, we have to work on the util service and write on top of it. Its price can also be better. It is pretty costly because they charge us for each transmission."

"The certifications and learning resources are not exposed openly enough. For instance, they have a trial version which comes with only a few basic features, and I think that community-wise they need to offer more free or open spaces where developers can feel encouraged to experiment."

"I'd like to see the admin portal for managing the integration server go up a level, to have more capabilities and to be given a more modern web interface."

"This solution could be improved by offering subscription based licensing."

"The patching of infrastructure is not very smooth and improved authentication should be added in the next feature."

"Understanding the overall architecture is difficult."

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."

"Most of my clients would like the price of the solution to be reduced."

"Its cost depends on the use cases."

"Sometimes we don't have a very clear idea what the licensing will entail at first, because it can be very customizable. On one hand, this can be a good thing, because it can be tailored to a specific customer's needs. But on the other hand it can also be an issue when some customer asks, "What's the cost?" and we can't yet give them an accurate answer."

"It is an expensive tool. I rate the product price a nine out of ten, where ten means it is very expensive."

"The product is expensive."

"webMethods.io is expensive. We have multiple components, and you need to pay for each of them."

"I am not involved in the licensing side of things."

"The pricing is a yearly license."
