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.

To improve IBM API Connect, based on customer experience, you could work on latency. You can increase scalability and availability. If you're connecting with any other cloud, it connects to the infrastructure which needs to be managed with the customers and cloud providers, so if you have a setup, we can handle it easily. I have faced latency issues on the server, related to our management. If you need to stabilize your server based on peak traffic, you need to configure the scalability model. You need to know when traffic peaks, so use auto-scaling when traffic comes. If the application is not in use, the value should be zero, and it starts from zero. Based on customer experience, the value will increase, and when there is no customer servicing, the peak would be reduced, making the value remain zero. Following this approach, you should be able to optimize costs and satisfy customer experience.

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

"WSRR is a powerful component for getting the endpoints."

"We are able to share those APIs instantly within the organization; even if we want to share it outside publicly, then we can have those capabilities."

"Scalable and stable API platform for creating and managing APIs."

"It is quite stable. We've not had any problem. It has made for a good buy because we are finding that other companies that have similar set ups go down maybe once a month."

"This product is well integrated with other products. Its ability to interact with IBM Secure Gateway and other integration products is the core feature. Also, the lead time to put it into production is relatively short ."

"The solution provides a common place for all APIs, allowing for easy sharing and exchange of information between internal and external stakeholders."

"The most valuable features are stability and security."

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

More IBM API Connect pros

"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."

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

"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."

"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 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."

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

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

Cons

"The initial setup and installation could be easier."

"It needs to be less taxing on compute resources."

"Improving the documentation would be beneficial as it currently presents navigation challenges. Incorporating a step-by-step guide could facilitate the integration or migration of various systems, including databases. The existing documentation only comprises plain text, hence incorporating more interactive instructions could enhance its usefulness."

"Business applications could be exposed to users."

"The installation was difficult with the IBM toolkit."

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

"The solution is not scalable."

"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."

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."

"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."

"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."

"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

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

"I rate the product price a seven on a scale of one to ten, where one is a low price, and ten is a high price."

"It's an expensive product."

"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."

"The pricing is significantly high."

"It is quite an expensive product."

"This is a licensed product. If your company is looking to obtain a license, you have to work with IBM partners."

"The price of the solution is very expensive, it can turn many customers away."
