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.

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

"The most valuable feature is it has lots of integration."

"API Gateway is easy to set up, allows for custom domain assignment and rate limiting based on customer tiers, and works well for defining different states for different customers based on their purchase plans."

"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 initial setup is straightforward."

"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."

"Amazon API Gateway facilitates our serverless architecture, particularly with Lambda, by allowing us to perform various tasks. For instance, Lambda functions authorize API calls, execute multiple workloads, and integrate with other services like Azure and Kubernetes. Additionally, we leverage Lambda functions behind the Amazon API Gateway to query databases, process data, and interact with different systems."

"Amazon API Gateway is a very fast solution."

"The solution is stable."

More Amazon API Gateway pros

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

"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 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."

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

"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 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."

More OpenLegacy pros

Cons

"Amazon API Gateway will wait for only 30 seconds to get a response from other services, such as the Lambda function."

"The integration could be improved."

"The only real problem is that you have to know a lot about what is outside of the API gateway in order to make the best use of it."

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

"I am not completely satisfied with Technical Support. They were finding it difficult to get to the AWS API gateway."

"The product's high price is an area of concern where improvements are required."

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

"Its performance and scalability could be better compared to one of its competitors."

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."

"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."

"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."

"Debugging and logging for programmers could be better."

Pricing and Cost Advice

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

"The pricing model for API Gateway is advantageous due to its serverless nature, as it depends on traffic volume."

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

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

"It is somewhat costly, particularly when it introduces server-related features, which are often scheduled on our end."

"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."

"There are no licensing fees."

"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 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."
