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

"What I like best about Amazon API Gateway is that it's simple to use, easy to set up, and you can quickly get it up and running. It's a very user-friendly solution. I also didn't experience any issues in terms of Amazon API Gateway interface, integration, or monitoring. The solution runs smoothly."

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

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

"It is a brilliant service and very helpful with our API-based applications because, as a service provided by Amazon, you do not need to maintain it or monitor the traffic; you can simply configure it and it is ready to use."

"The solution is solid, robust, and scalable."

"The technical support is very strong, and we've had issues with the solution and configuration and we've gotten very good support."

"The scalability is very good."

"In terms of scalability, I haven't encountered any issues with API Gateway. We've significantly increased our traffic from hitting it once or twice a minute to now hitting it ten to fifteen times within a minute. In an hour, we're receiving hundreds of hits. So, it's performing excellently."

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."

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

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

"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."

"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."

"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."

More OpenLegacy pros

Cons

"If I take into consideration the past three to four years, during which I used the tool, I would say that some missing and external configurations were not possible in the product, and it was a bit difficult to manage."

"One of the problems with using this solution is that you have to know a lot about the Amazon ecosystem, in terms of services, to be able to use it."

"API Gateway lacks some governance features that MuleSoft offers, and there are additional features that could make it even better."

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

"An audit trail and audit stamps managed at the API level to control API movement would be beneficial."

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

"The integration could be improved."

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

More Amazon API Gateway 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."

"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."

"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."

"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."

Pricing and Cost Advice

"Azure products are more cost-effective than AWS solutions"

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

"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 product is expensive."

"Amazon API Gateway has various pricing plans, but I cannot give the exact cost, though I can say that it's expensive. On a scale of one to five, I'd rate the pricing for Amazon API Gateway as two, as the solution is one of the most expensive products in the market for API management."

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

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

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