Integration with backend systems and runtime configuration simplicity enhance operational efficiency
Apache APISIX is easy to configure. It supports coding for filters and can integrate with many languages. Its configuration at runtime is very easy. You can configure your gateway at runtime without needing to restart the gateway to apply configurations. This is a perfect feature. The service discovery feature integrates with backend systems and provides powerful load balancing. Also, its integration with Keycloak and authorization systems is a valuable feature.

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

"I recommend Apache APISIX to others because of its many useful features."
"The most valuable features of Apache APISIX include routing for upstream and frontend services, masking using proxy rewrite, and the integration of different plugins like Prometheus and Grafana."
"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."
"The product has helped our business by allowing us to become more efficient in data handling."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."
"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."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
 

Cons

"The user interface is limited and does not support all features of Apache APISIX."
"The routing algorithms in Apache APISIX, such as node-based and round-robin, could be improved. Introducing more plugins and supporting AI features can enhance the solution."
"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."
"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."
"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."
"Debugging and logging for programmers could be better."
"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."
"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."
