ASHOK YADAV

Solutions Architect at a financial services firm with 1,001-5,000 employees

Offers OIDC, Rate Limiting, Lambda functions but lacks software upgrades

Upgrading Kong Gateway Enterprise should be more sophisticated and innovative. The main issue is with the update process. Our DevOps and admin teams need to update multiple files, which is cumbersome. For instance, in cases where Palantir countries are involved, they have to update many files, which is not ideal. However, for other tasks like configuring the message routing and services and handling all the configurations, the process is acceptable. The software version upgrade process should be improved. Additionally, the DevOps portal should be integrated more natively. There are a few other areas for improvement, such as implementing automatic load balancing. The status of the office team, whether it is up or down, should be checked at the API gateway level to facilitate load balancing.

VP, Chief Enterprise Integration Architect at a financial services firm with 10,001+ employees

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

"Good at intercepting traffic and modeling APIs around that."

"Protocol transformation is the most valuable feature of Kong Enterprise."

"It boasts remarkable speed and stability, and these qualities, particularly the gateway's resilience, are standout features for me."

"It offers a wide range of plugins that we leverage, including OIDC, Rate Limiting, Lambda functions, and more."

"The solution's technical support is good and fast in terms of responsiveness and problem-solving skills."

"In our buying companies' perspective, it was easier to use compared to other platforms. The markets were pretty familiar with the solutions."

"The features I like include ease of operation and implementation in a cloud environment, the dashboarding features for API statistics, and the user-friendly developer portal."

"We use the solution for load-balancing, caching, and rate-limiting APIs."

More Kong Gateway Enterprise pros

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

"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."

"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 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."

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

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

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

Cons

"Kong Enterprise needs to improve its pricing, which starts at hundreds of thousands of dollars. Pricing should be based on API usage rather than monthly. It should improve its documentation as well."

"They could focus more on pricing."

"The main challenge, in my opinion, is the price. It's difficult to convince our management to approve the budget to purchase it from our vendor. There are no technical problems."

"The ease of billing is lost when Kong is not available directly on the Azure marketplace. This is one area where they can improve."

"The technical support team's response time needs to be improved."

"The developer portal needs to be improved."

"Kong is meant for north-south communications, so it will be interesting to see what solutions they can come up with in the realms of east-west communications, service-to-service communications, and Zero Trust architecture. I believe that if they can provide for these areas, then they will be able to solve the overall integration and security concerns for microservices architecture in general."

"It becomes difficult if you try to scale it up to multiple clusters."

More Kong Gateway Enterprise 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."

"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."

"Debugging and logging for programmers could be better."

"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."

Pricing and Cost Advice

"The product is reasonably priced because it goes by the SaaS model."

"It's expensive in Thailand (10 million baht, in Thai currency)."

"The price is really reasonable compared to that of alternative solutions."

"The licensing is expensive."

"Basically, my company uses the tool's open-source version."

"Kong Enterprise is cheaper than Apigee. I rate its pricing as four out of ten."

"Kong Enterprise's pricing is at par compared to the other technologies."

"I don't have any information on licensing costs currently."
