Has required significant improvements due to limited features but offers simple implementation and good support

Boomi AtomSphere API Management has very few features. If you ask me to name the top two, I would say MuleSoft and Apigee, as it depends on the customer-to-customer use cases. After those, WSO2, Kong, and whether you say Informatica API Manager or Boomi AtomSphere API Management, they stand with only three out of ten features which are essential for API management. All the features that Apigee has, they need to add. All the features that MuleSoft has, they need to add. It is not a simple task. The problem is that they lack features. It is not their performance. There are many features to mention. When you take and compare all the features that Apigee has and all the features that MuleSoft has, they need to implement those features.

The biggest advantage is how simple the technology was.

I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be. OpenLegacy handles the bread-and-butter TP monitoring stuff, but I am working for one of the six banks in the United States still using the Hogan mainframe, which has a slightly proprietary mechanism. But OpenLegacy currently doesn't have a connector for Hogan. So it would help if they could build one. That would appeal to financial institutions that still use Hogan, like US Bank, Wells Fargo, KeyBank, and Vanguard.

Quotes from Members

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

Pros

"Boomi AtomSphere API Management is a good product for integrating with Boomi as a backend service."

"The stability of the solution is good."

"Integrations take less time."

"The user interface, which we use to create the integration, basically has the data structures collected, is pretty easy to navigate, is a drag and drop style of working, and there is very little code required so the creation of the endpoints is very simple."

"We can create APIs straightforwardly and quickly and build jobs for data migration."

"AtomSphere API Management is a simple platform that's easy to use. If you're using it on-prem, there's a little learning curve."

"The product's stability is good."

"Boomi allows for more secure URLs and easy customization of HTTP and HTTPS protocols, which I find very beneficial."

More Boomi AtomSphere API Management pros

"Without OpenLegacy, it would take us several months to create the same services."

"The product has helped our business by allowing us to become more efficient in data handling."

"Using OpenLegacy, the exposure of services is far easier and quicker. In many cases, exposure of services requires just a few clicks and takes only minutes. In very complex cases, it still only takes half a day. Without OpenLegacy, it would take us several months to create the same services."

"It is possible to solve larger legacy API issues on an enterprise level with this product."

"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."

"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."

"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."

"OpenLegacy provides a way to go from the outside world to the legacy mainframe, to move the old standard application to a REST API application. New digital services can be created in a few clicks and this can be done easily by COBOL programmers."

More OpenLegacy pros

Cons

"Boomi AtomSphere API Management has very few features. If you ask me to name the top two, I would say MuleSoft and Apigee, as it depends on the customer-to-customer use cases."

"It's difficult to integrate the on-prem application with the Dell Boomi Cloud. We have to check to ensure the Dell domain engine is running. It just requires some service endpoints from our on-prem application to connect to Dell Boomi Cloud to make it available to integrate. It would be better if AtomSphere API Management were offered as a purely SaaS application, so I wouldn't need an on-prem component to make it available. We could make a test call or provide some connection parameters. That should enable it to pull the data."

"The API management has room for improvement."

"The product is really complex to manage."

"Scalability is an area where Boomi lacks."

"The solution must provide more AI services."

"Boomi AtomSphere API Management can be improved in terms of threshold management and policy management."

"Most of the basic functionality is there in Boomi, but APG is a more feature-rich solution."

More Boomi AtomSphere API Management cons

"We would also be more than happy if the product had the option to work in the opposite direction – the ability to consume REST/SOW services in the outer world from the mainframe."

"I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be."

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."

"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case. We are currently working with OpenLegacy to cross the SSL bridge and suspect that most users will want to do the same."

"Debugging and logging for programmers could be better."

"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."

Pricing and Cost Advice

"The price is reasonable."

"Boomi AtomSphere API Management gives customers a good price. Price-wise, the product is good."

"The product can get very expensive quickly if you connect to multiple databases."

"Boomi AtomSphere API Management is a cheap product."

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
