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

"IBM API Connect is a reliable and scalable solution."

"One of the most valuable features is that we can seamlessly and harmoniously expose our capabilities, from a security point of view."

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

"It has all of the tools that are needed for the specific mission."

"The most valuable features are stability and security."

"The centralized management: this provides a management module that can deploy and apply security policies to all APIs, including all the gateways that are deployed on-premises and on any cloud because the gateway component can run at a VMware or in a Kubernetes cluster."

"The management of the API and API portal is good."

"It's quite flexible and easy to deploy, especially for beginners. It has almost all the features that an API gateway should have."

More IBM API Connect pros

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

"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."

"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."

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

"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."

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

Cons

"It would be helpful to have access monitoring."

"The platform’s integration with the payment gateway needs enhancement. The setup process and support services could be improved."

"The solution could improve security and performance."

"Installation is weak."

"We would have more capability to interact with the catalog and inventories, so a more DevOps-friendly solution is needed."

"The installation process could use improvement. I hope that in the next release, the installation process is easier."

"Support for this platform could still be improved. It also needs to have more levels of versatility. Its compatibility and integration with different platforms also need improvement."

"The only disadvantage I can see is that it requires heavy hardware support."

More IBM API Connect cons

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

"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."

"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 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."

"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."

Pricing and Cost Advice

"We pay for the IBM API Connect monthly. We only need to pay the standard licensing fee."

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

"IBM API Connect could be cheaper."

"It is a pretty expensive tool."

"It is quite an expensive product."

"The price for IBM API Connect is reasonable. It's $20,000 to $30,000 yearly for a subscription, and the pricing could vary around $40,000 per year, per subscription. Its price is reasonable for customers who have around sixty million API calls yearly for unlimited environments."

"It's an expensive product."

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

"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."
