User-friendly platform simplifies traffic management and boosts API management through integrated plugins

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. These plugins are self-integrated, allowing features like JWT authentication, rate limiting, and diverse authentication methods without extra integration. The tool is beneficial for its plugin orchestration which enhances API management with redirection, response rewrite, key authentication, and observability with Grafana and Prometheus.

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.

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."

"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 connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."

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

"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."

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

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

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

"Opens the door to connect modern web products to an old legacy system."

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."

"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."

"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."

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