Rahul Kundu - PeerSpot reviewer
Cost-effective serverless routing with room for extended timeout settings
We are using API Gateway to route the traffic to our Lambdas. Every API pass is linked to some of the Lambdas. When traffic hits CloudFront, it redirects it to API Gateway, which then redirects it to the respective Lambda server. We have different kinds of services invoked through these Lambdas…

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

"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."
"API Gateway is out of the box and works well with Amazon products."
"t is easy for integrations if it is deployed in AWS Services."
"The solution is a managed service and requires minimal configuration, which makes it easy to launch an API."
"All information and data needs to be sanitized before it enters a private domain and we use this solution to do this."
"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."
"It is easy to set up. It is also quick to deploy."
"The initial setup is pretty easy. Deployment only takes five minutes."
"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."
"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."
"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."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"Opens the door to connect modern web products to an old legacy system."
"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
 

Cons

"Amazon API Gateway can improve the user interface in some areas it could be more polished."
"I am not completely satisfied with Technical Support."
"I would say Amazon API Gateway is a bit costly, but considering the feature level, it is very good."
"From a use cases perspective, you need to have an internal and external gateway. AWS can only handle external traffic so has to be used together with another solution."
"A lower price would definitely be an improvement."
"The tool's UI requires time to understand."
"We faced a few issues with the documentation."
"API Gateway lacks some governance features that MuleSoft offers, and there are additional features that could make it even better."
"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."
"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'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."
 

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."
"There are no licensing fees."
"The product is a little expensive."
"Amazon API Gateway is a very cheaply priced product."
"Azure products are more cost-effective than AWS solutions"
"I rate the platform's pricing a five out of ten."
"The product is expensive."
"Fees are volume-based."
"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."
