Executive SummaryUpdated on Dec 17, 2024

IBM API Connect and OpenLegacy are competing products in the API management category. IBM API Connect appears to have the upper hand with its extensive features and integration capabilities tailored for enterprise environments, while OpenLegacy's modern technology and quick deployment options make it an appealing choice for businesses seeking agility and cost savings.

Features: IBM API Connect offers extensive API lifecycle management, robust security, and in-depth analytics, making it suitable for large enterprises needing comprehensive control and insights. OpenLegacy excels in rapid legacy system integration and microservice generation, which is ideal for organizations focused on modernization and operational streamlining.

Room for Improvement: IBM API Connect could improve its deployment process, which tends to be complex due to its wide range of capabilities, potentially extending initial setup time. Documentation could be more user-friendly to facilitate quicker installations. It would also benefit from enhancing its microservice support further. OpenLegacy can improve upon scalability for very large enterprise demands, expand its analytics capabilities to match those of its larger competitors, and increase its cloud integration features for hybrid environments.

Ease of Deployment and Customer Service: OpenLegacy provides a straightforward deployment model, minimizing time-to-market with streamlined processes suitable for legacy systems, and it focuses on responsive customer service. IBM API Connect offers comprehensive support and documentation but tends to require more setup time due to its extensive capabilities, which can be intricate for users unfamiliar with its system.

Pricing and ROI: IBM API Connect has a perceived higher setup cost; however, it promises a strong ROI for enterprises that can fully leverage its extensive range of features over time. OpenLegacy presents a cost-effective solution with fast ROI, especially attractive to businesses aiming to reduce costs while modernizing efficiently without significant initial investments.

Offers basic API orchestration and provides robust security and governance features

While Azure API Management offers configurable scalability, IBM API Connect relies on Kubernetes clusters. This might seem manual and require defining cluster instances upfront, but it's completely customizable and not on-the-fly scaling. It's completely custom-driven, not on-the-fly scaling, which some may consider cumbersome. Overall, I would rate the scalability an eight out of ten. Almost all applications we've been exposing lately go through this middleware, so it's used extensively. There are around sixty applications directly using it, but six Kubernetes clusters serve those applications. It's heavily used for integration, including system-to-system integration and product integrations. Our usage has been increasing year-on-year based on our needs.

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

"DataPower Gateway holds significant value for us as it serves as the cornerstone of our enterprise security controls."

"The most valuable feature for me is the ability to distribute work among our API developers, so we don't have to do all the work as IBM API Connect administrators and IBM DataPower administrators."

"The ability for all of our web applications to share standard functions and documents easily is valuable."

"The solution is very stable."

"In-built policies and security functions."

"It offers enhanced security features to protect APIs, enforce access control, and secure sensitive data."

"API Connect's data gateway is one of the strongest in the market."

"The most valuable feature is the security we get from this solution. I know of a bank that uses it to ensure that everything is secure. The second feature I like is the retail environment, where we actually want to be able to provide as many suppliers and consumers with APIs as possible. If you are well-trained in the writing of RESTful API's, you can actually publish an API in a matter of minutes, test it, and publish it."

More IBM API Connect pros

"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 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."

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

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

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

"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."

Cons

"There is room for improvement regarding the connectivity of the DevOps."

"Automation for our Domino applications could be improved."

"It's based on a little bit dated architecture. A lot of evolution has happened after that. It's an evolving field. Kong is a Kubernetes-based platform. Kong runs on Kubernetes, but all the other ones are in microservices. So, there's a lot of improvement that can be done."

"I would like to see support for non-Java based services. We struggle a bit to be able to deploy and connect our .NET services because of things like data types. We had to map a couple of things. For one solution provider, we had to move them to .NET Core before we could use it properly. I would like to see more agnostic tool service platforms rather than moving it more towards Java or open source."

"The solution is overly complex."

"We've had some issues upgrading to the latest version of the solution."

"They seem to have left out a feature for microservices and also a certification module for OIDC."

"Business applications could be exposed to users."

More IBM API Connect cons

"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."

"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."

"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."

Pricing and Cost Advice

"Pricing for IBM API Connect varies, e.g. it could be subscription-based. Deploying it on private cloud also means you have to own most of the software licensing."

"It is a pretty expensive tool."

"IBM API Connect could be cheaper."

"API Connect is expensive - I'd rate their pricing five out of ten."

"It is quite an expensive product."

"The price of the solution is expensive. However, there are a lot of customization capabilities."

"The pricing is too expensive with IBM. Sometimes, we prefer to go with an open source or something more lightweight."

"API Connect is quite pricey."
