Offers strong integration capabilities and reliable features but needs pricing and scaling improvements
Many things are evolving with the AI buzz in the market. What I would like to see improved or enhanced in webMethods.io in the future is that since webMethods.io is already under IBM, I think IBM will introduce and integrate AI into it. Additionally, regarding what webMethods.io can improve is the license cost. Other cloud players are also providing the same kind of functionality, such as AWS and Azure. webMethods.io is being installed on-premises, but AWS is providing it directly in the cloud. When comparing the license cost and request per minute cost, webMethods.io needs to address that. There are many competitors in the market for this.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"There is no limitation when it comes to integrating multiple applications, which is a reason I appreciate it."
"The most valuable feature of the webMethods Integration Server is its reliability. It has a lot of great documentation from the service providers. Additionally, it is easy to use."
"The time to market is relatively less, it's simple to learn for Java users, its administration is easier, and it has an extensive toolset with out-of-the-box libraries support."
"This solution is flexible and can be used across a number of projects."
"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."
"webMethods API Portal is overall very valuable. It is now a comprehensive API catalogue that serves various purposes, including API assessment and evaluation."
"Best feature is Insight for monitoring, and as a debugging tool. It has saved us a lot of time during crisis situations."
"Overall, this is a pretty good product."
"Millions of people were connecting every month on the system and there were no issues."
"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 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 our clients is a signature company and developed on a classic Java enterprise application using OpenESB, and in one year they saved £20,000,000 on development and maintenance."
"The core is very stable."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
 

Cons

"I am not satisfied with the solution because it takes too much effort to migrate and add new information. The migration could be easier."
"Programming model with flow is hopelessly outdated."
"webMethods.io does not currently have certain features, and we have to do coding as well."
"They keep producing new versions at a rate that we cannot keep up with. That is a problem for us because they have a very small set of supported versions."
"I would like the solution to provide bi-weekly updates."
"We'd like for them to open up to a more cloud-based solution that could offer more flexibility and maybe a better rules engine or more integration with rules engines."
"The learning curve is a little steep at first."
"The product must add more compatible connectors."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"Regarding its management, a web console being able to synchronize distributed instances would be great."
"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."
 

Pricing and Cost Advice

"The price is a little bit high, especially regarding their support."
"The product is very expensive."
"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 worth the cost."
"It is a cost-effective solution."
"The product is expensive."
"I signed a three-year deal with them. It is a yearly locked-in price for the next three years."
"There is a license needed to use the webMethods Integration Server."
"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."
"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."
