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

"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."

"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."

"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."

"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 process-oriented solution allows you to define choreography and orchestration."

"Millions of people were connecting every month on the system and there were no issues."

"The core is very stable."

"A product with good API and EDI components."

"This is a middleware tool from Software AG, so when there is a need for EAI/ESB, or B2B; the use cases and implementations are plenty and can vary according to business and enterprise architecture."

"The stability is good."

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

"One of the most important features is that it gives you the possibility to do low-level integration, provides a lot of features out of the box, and over the years, it has matured so much that any problem that is there in the market can be solved with this product."

"The solution has a very comprehensive and versatile set of connectors. I've been able to utilize it for multiple, different mechanisms. We do a lot of SaaS and we do have IoT devices and the solution is comprehensive in those areas."

"The MFT component of webMethods, for example, is easy to set up and convenient to use. It handles files very efficiently and it is easy to automate tasks with complex schedules. Monitoring is centralized to MWS which can be used to monitor other products as well (Trading Networks, BPM, MFT, etc.)"

"Best feature is Insight for monitoring, and as a debugging tool. It has saved us a lot of time during crisis situations."

Cons

"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."

"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."

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

"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 needs to be better."

"The documentation needs to be better — maybe they could add more accurate tutorials."

"I would like the solution to provide bi-weekly updates."

"The interface needs some work. It is not very user-friendly."

"The Software AG Designer could be more memory-efficient or CPU-efficient so that we can use it with middle-spec hardware."

"Documentation needs tuning. There is a lot of dependency with SoftwareAG. Even with the documentation at hand, you can struggle to implement scenarios without SAG’s help. By contrast, IBM’s documentation is self-explanatory, in my opinion."

"Pricing is the number-one downfall. It's too expensive."

"In 2008, the technical support's response time was much longer than expected."

"webMethods Integration Server could improve on the version control. I'm not sure if Web Method has some kind of inbuilt integration with Bitbucket or GitHub or some kind of version control system."

"Understanding the overall architecture is difficult."

Pricing and Cost Advice

"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."

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

"With our current licensing, it's very easy for us to scale. With our older licensing model, it was very hard. This is definitely something that I would highlight."

"Its cost depends on the use cases."

"The pricing is a yearly license."

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

"The solution’s pricing is too high."

"webMethods Integration Server is expensive, and there's no fixed price on it because it has a point pricing model. You can negotiate, which makes it interesting."

"The price is a little bit high, especially regarding their support."
