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

"Easy to configure security and generate API keys."

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

"The fact that the product can provide both security and scale to quite a large number of products, is basically the reason why we chose it, and that's what we like about it."

"IBM API Connect made this control quite easily, and we could see in the dashboard when someone made too many requests."

"Since it runs on top of Datapower, all Datapower based custom policies can be utilized and exported to API connect but its not straightforward/simple process."

"It gives a holistic environment for us to set up the APIs and that's the main value that it adds. It gives end to end for us."

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

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

More IBM API Connect pros

"OpenLegacy opens the door to connect modern web products to our 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."

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

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

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

"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."

More OpenLegacy pros

Cons

"Firstly, the pricing model, when compared to other open sources, is high. Secondly, the availability of resources in the market, specifically the developers available in the market, is not so much."

"Custom code needs to be written in order to connect to MQ and exchange messages. This can be achieved, but it is a tedious task."

"Extracting the data could be improved."

"Understanding the architecture, deployment criteria, and communication methods of the installation can be time-consuming."

"Integration with Exchange Server. Also if it could be easier to configure or direct the DataPower policies that would help."

"Possible improvement is mainly around having more of the cloud oriented architecture bringing stability in adding new capabilities around security."

"I rated it an 8/10 because it's not fully mature yet."

"Our main pain points are in these two areas: creating a better developer portal and improving stability in terms of synchronization and monetization."

More IBM API Connect cons

"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."

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

"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."

Pricing and Cost Advice

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

"There was a need to purchase an upfront license or a one-time license or upfront license, but I cannot remember the details about it clearly."

"The pricing is significantly high."

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

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

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

"It is a pretty expensive tool."

"API Connect is quite pricey."
