Executive SummaryUpdated on Dec 17, 2024

Amazon API Gateway and OpenLegacy are competing products in API management and integration. Amazon API Gateway has the upper hand in environments using AWS services due to its seamless integration and cloud-native attributes, whereas OpenLegacy is preferred for modernizing legacy systems with robust support.

Features: Amazon API Gateway offers seamless integration with AWS services, exceptional scalability, and advanced security capabilities. OpenLegacy efficiently exposes and modernizes legacy systems, provides flexibility integrating with diverse back-end systems, and effectively reduces the complexity of adapting to legacy architectures.

Room for Improvement: Amazon API Gateway could enhance support for non-AWS environments, improve monitoring tools, and offer more flexible pricing options. OpenLegacy may benefit from optimizing its documentation, strengthening security features for cloud environments, and expanding support for different legacy systems to cover a wider range of technologies.

Ease of Deployment and Customer Service: Amazon API Gateway, being cloud-based, supports streamlined deployment processes with comprehensive AWS integration and documentation. OpenLegacy offers flexible deployment with on-premise and cloud options, prioritizing tailored support for complex legacy integrations and providing practical solutions for hybrid environments.

Pricing and ROI: Amazon API Gateway's pay-as-you-go pricing model supports cost predictability for scalable AWS environments, offering significant ROI for cloud-native applications.

Faced challenges with audit trails and seek better user-level monitoring and control

Regarding built-in authorization, monitoring is quite substantial, and versioning systems is also what we are using. With Amazon API Gateway, we utilize a variety of deployment methods and services they provide, so monitoring services are the important parameter in API control from our side, allowing us to see how the APIs behave and how well they pick up the data from their respective sources. Integration with AWS Lambda has been beneficial since we have event controllers that help identify the APIs, which then call the API from the API services. We're managing this with events that are parameterized through API identification, mostly using Python in Lambda, which has inbuilt features to track API lifecycle parameters. The defined parameterized features in Amazon API Gateway help streamline API lifecycle management. Our AWS system admin team sets these configurations for us. The versioning number gets updated as we deploy revised API versions, which gets monitored on the API monitoring services. The cloud engineering team assists us as we are from a solutions development and deployment team. The importance of Amazon API Gateway's global API deployment for our application's performance is significant in terms of scalability and availability. Amazon API Gateway services have been very good, maintaining a 99.99 SLA, providing us confidence in the global deployment level as it is capable of handling various endpoint types, such as database sites and legacy systems.

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

"It is very helpful, with our API-based applications."

"The scalability is very good."

"A most valuable feature of Amazon API Gateway is how quickly we can connect to backend services and have APIs accessible from anywhere."

"The initial setup is pretty easy. Deployment only takes five minutes."

"One of the most valuable aspects of API Gateway is its native integration with AWS services."

"The initial setup is straightforward."

"The solution is a managed service and requires minimal configuration, which makes it easy to launch an API."

"The Lambda features are very cost-effective since you do not have to run your servers 24/7."

More Amazon API Gateway pros

"The product has helped our business by allowing us to become more efficient in data handling."

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

"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 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."

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

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

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

More OpenLegacy pros

Cons

"API Gateway could improve by allowing debugging capabilities, particularly when dealing with high volumes. At scale, it is expensive, and latency sometimes occurs."

"The user interface could be improved, as well as customer support and having a local customer representative in a country."

"Amazon API Gateway can improve the user interface in some areas it could be more polished."

"I'm pretty happy with what Amazon API Gateway offers, but as its pricing is on the higher side, that's one area for improvement in the solution."

"Amazon API Gateway is not as complete as Apigee and needs to be improved by adding more features to become a more robust application."

"When it comes to DDoS protection, I would like to see that become available at the API Gateway level."

"The solution should include change data capture (CDC) features that will help reduce workload"

"The solution could improve signature validation."

More Amazon API Gateway cons

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

"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."

"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."

"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."

"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."

Pricing and Cost Advice

"I am satisfied with the price."

"My understanding is that it easily goes to $14,000 or $15,000 USD each month for each account, and we have several such accounts."

"The solution is expensive. Though the product was previously available at a cheap rate, nowadays it is expensive."

"Since it's a serverless solution, Amazon API Gateway is not so expensive."

"I rate the tool's price as seven on a scale of one to ten, where one means low price and ten means high price."

"There is an annual licensing cost to use Amazon API Gateway."

"This is a pay-per-use service, where you only pay for what you use."

"Fees are volume-based."
