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.

API management has strengthened security and monitoring but still needs better support and tooling

There are areas of IBM API Connect that need to be improved. I want what Gravitee made, which is much better. Gravitee made many samples for different use cases. First of all, they made examples of use cases, codes, and what the module expects and what the module returns for multiple examples and use cases inside the development. I do not even have to go to the documentation website because everything is included inside the tool when I work on it. This is great, in fact. IBM API Connect should show examples. One other thing is the support. The support of IBM is in India. Every time I want to ask something, they say they need logs, they want this, they want that. Gravitee API asks me to explain the problem without asking a thousand times as if it is a request for a green card in the USA. Then they really explain quickly. IBM is a big company, so everything is standardized with the approach of "You do that, you do that, you request that. If you do not have that, you do not reply to the client." Clients want flexibility today, even if it is a huge company. A stressed client is a client that will want to change to other flexible solutions. When everything is fine, we do not care, but when there is stress and problems, that is when the customer of IBM evaluates the tool really. It is when there are problems. IBM makes a lot of efforts on sales and technical sales, and then that is it.

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

"The solution offers a pretty good SLA."

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

"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."

"Scalability is good."

"The most valuable features are: 1. 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."

"Its speed and performance are valuable."

"API Connect is an easy-to-learn, very advanced, reliable, business-to-business API management product."

"API connect is far better, faster and sleek as compared to IBM API management."

More IBM API Connect pros

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

"Without OpenLegacy, it would take us several months to create the same services."

"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."

"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 opens the door to connect modern web products to our old legacy system."

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

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

More OpenLegacy pros

Cons

"I have faced latency issues on the server, related to our management."

"The only downside where improvements are needed is probably on the licensing side."

"Documentation for the CLI is not very complete. Also, the support could be improved, and we have had several problems with backing up and restoring the product."

"IBM is also a bit pricey. On top of that, they have bugs that need to be fixed."

"My rating reflects the fact that it's not operationalized at this point, and that's not entirely the product’s fault."

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

"Automation for our Domino applications could be improved."

"The automation and the simplicity could be improved."

More IBM API Connect cons

"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."

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

"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."

"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case."

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing."

"Debugging and logging for programmers could be better."

More OpenLegacy cons

Pricing and Cost Advice

"The pricing is significantly high."

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

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

"API Connect's license cost could be a little lower. But, unfortunately, there aren't many open-source API gateways. Ideally, some new developers could come up with a minimum-functionality open-source solution."

"I haven't seen anyone go from on-premise to the cloud. In fact, I am seeing people go from the cloud to on-premise because the costs can quickly grow on the cloud."

"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."

"It should be cheaper. It has a yearly licensing."

More IBM API Connect pricing and cost advice

"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."
