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.

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

"Our version supports containerized integration. I can write APIs, which can be moved into a testing environment without needing a forklift. It can check if APIs are compliant before moving them into production."

"IBM API Connect has a designer and CLI features which can be used to completely automate the API, so if a business analyst has a basic understanding of what the input and output payload is, they can directly create the API."

"The solution offers a pretty good SLA."

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

"The functionalities on offer are very good."

"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 solution is ready to scale and already supports our agile CICD."

"Easy to configure security and generate API keys."

More IBM API Connect pros

"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."

"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."

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

Cons

"The implementation process could benefit from improvements, as it may take some time to become accustomed to the deployment."

"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."

"API Connect's analytics subsystem could be improved to make it easier to render content from the analytics system and offload it to an external database."

"The design time setup has a lot of customizable fields, but we need certain standard fields to be added, such as what all of the consuming systems are. This needs to be very clearly articulated during the design time."

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

"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 integration of an API gateway that implements the sidecar pattern, which can be deployed in cloud applications, and expose the microservices directly in each pod, this can be more decentralized components."

"There are some performance issues and issues related to asynchronous APIs."

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."

"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."

"Debugging and logging for programmers could be better."

Pricing and Cost Advice

"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."

"API Connect was highly expensive for us, but the decision to switch was made before I joined the company. It seems like the company bought it, but they didn't know how to use it. After two years, they decided to reevaluate and conduct some cost estimates."

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

"It is quite an expensive product."

"IBM API Connect could be cheaper."

"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 an expensive solution. The licensing model is based on a per-subscription and per-subscriber end-user basis, meaning the price is determined by the end-users of the platform."

"It is a pretty expensive tool."
