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. OpenLegacy involves higher initial setup costs due to its tailored solutions but yields high ROI in legacy modernization projects, making it invaluable for transforming outdated systems.

Architect at Birlasoft IndiaLtd.

Strong technical support and effective toolset improve workflow but setup process requires refinement

I have experience with Nintex and K2, but I do not have experience with Unqork. I am specialized in Microsoft products such as Power Automate and Power Apps. I have knowledge of Microsoft Intune and Defender, along with certain Azure components. I work for an organization as a presales architect, proposing solutions to customers. I am familiar with Microsoft Defender for Identity, for Business, and for IoT, though I haven't worked extensively on that. I have a conceptually good understanding of it. I'm mostly working on Microsoft collaboration tools, which include SharePoint and Power Platform tools. I have been dealing mostly with Microsoft, but also with other vendors. Regarding database services, we typically use SQL server services. We have not used Amazon RDS; typically, we use PostgreSQL or MySQL. On the Azure side, I work with Azure Database services including PostgreSQL, MySQL, and SQL Cosmos. I was previously working as an architect for U3Soft and am currently working with Birlasoft (B I R L A S O F T). My overall rating for Amazon API Gateway is 8 out of 10.

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 is stable."

"API Gateway is out of the box and works well with Amazon products."

"The Cognito authorization integration is very useful, along with the easy multi-region integration and connectivity with various AWS services like SQS, SNS, and Lambda functions."

"Amazon API Gateway can integrate with ECS and Lambda."

"All information and data needs to be sanitized before it enters a private domain and we use this solution to do this."

"The product is really good when it comes to API lifecycle management, and it is not just something that includes the balancing part or the security aspect but also the routing and the fallback mechanism."

"The best features of Amazon API Gateway include security and metering, which involves the analytical part of how the APIs are being consumed since it's for consumer APIs built for use by other applications."

"In terms of most valuable features, it would say that it is really easy to start working with it."

More Amazon API Gateway 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."

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

"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 solve larger legacy API issues on an enterprise level with this product."

"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."

"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."

Cons

"Amazon API Gateway needs to focus on minimizing latency."

"When using APIs, the manual bit for intermediate confirmation with VTL can be a challenge."

"API Gateway could improve by allowing debugging capabilities, particularly when dealing with high volumes."

"Like most Amazon services, and this one's the same, you're expected to effectively do your own support, and any other support is by emails, so it's quite limited."

"The pricing could be improved. In cases where customers require real-time sync or real-time calling groups with IoT, the volume of data and time lag become a concern."

"A lower price would definitely be an improvement."

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

"Their support services come at a considerable cost, leaving room for improvement."

More Amazon API Gateway cons

"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."

"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."

"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

"AWS charges for data ingress and egress, which could be further reduced. This would be helpful for customers dealing with large amounts of data coming in or going out from their systems."

"The solution's pricing is cheap and based on the number of requests coming to Amazon API Gateway."

"It's cost-effective, even as our workload and the number of APIs we manage have increased."

"The product is a little expensive."

"I am satisfied with the price."

"The solution's price is reasonable."

"I rate the platform's pricing a five out of ten."

"The product can be described as a medium-priced solution, but its cost is higher than Azure."

"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."
