Security features excel but development limitations emerge

We are using the IBM DataPower Gateway for security purposes. As per the development perspective, there are some limitations with IBM DataPower Gateway because it only supports XML and XSLT language, but it does not support the Java language. This is the only limitation of the IBM DataPower Gateway. For the authentication and authorization purpose, we can use the IBM DataPower Gateway. It's a very good product. We are mostly using the IBM DataPower Gateway for security purposes and load balancing purposes. If we are handling the load for a particular server, then we can use the IBM DataPower Gateway. The IBM DataPower Gateway is mostly used for security purposes. If we have some APIs and we are using some security for those APIs, then we can use it. It can also be used as a load balancer. It's also used for certificate management, user management purposes, authentication, and authorization. For routing, the IBM DataPower Gateway has multiple URL-based routing and content-based routing capabilities. If we have multiple URLs, then we can use an XML script. Using the XSLT language, we can configure multiple URLs and implement URL-based routing. Content-based routing means if we have multiple requests, we can route the request to a particular URL. For this, we need to use the XSLT language only. We can't use XML, Java, or other scripting languages. With IBM DataPower Gateway, we are using all the APIs. All APIs have been configured on the gateway. We have configured the particular TLS profile and some TLS client profiles as well. Using that TLS profile, we have configured the APIs and authentication. We have configured some tokens also, including JWT tokens and different types of auth tokens. There is also a rate limiting feature which we use for handling API loads.

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 very easy to work with."

"It is very easy to set up and configure, even for users with no prior experience."

"We did not experience any downtime, even if the number of transactions increased heavily."

"I like the tool's security. Also, all functionalities are integrated within on platform."

"DataPower Gateway is a perfect product, and I would recommend using it because it provides a lot of benefits."

"It can look for the various security threats, productions, payload scanning, and perform routing based on the content type."

"I like all of the features in this product and it does what it's supposed to do."

"The solution is robust, and we use the appliance version, which comes with good security features and troubleshooting tools, so we are happy with IBM DataPower."

More IBM DataPower Gateway pros

"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."

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

"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."

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

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

"It is possible to solve larger legacy API issues on an enterprise level with this product."

More OpenLegacy pros

Cons

"I noticed that the Gateway Script libraries could be improved, as they are not covering everything I need."

"From the development perspective, it has limitations because it only supports the XSLT language. It does not support multiple languages."

"The programming language is only supported in XSLT and Gateway script."

"The user interface or the application development perspective and customization of the tool could be a little better."

"It is a costly product."

"The two biggest issues of this solution are the complexity and the maintenance procedures."

"The IBM community does not have much engagement from the IT community in Saudi Arabia and developers for this solution are difficult to find."

"This solution is not scalable for our environment."

More IBM DataPower 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."

"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."

"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

"The solution has a return on investment but is a little expensive."

"Most customers' use case budgets are not inlined with the price of IBM DataPower Gateway. It is too expensive."

"It is an expensive solution."

"The tool's initial costing is expensive for small banks and financial institutions."

"The cost of this product varies from customer to customer and the relationship with IBM, including how many offerings from IBM are already being used."

"As far as I know, they have a perpetual license for this product. They are paying perpetual fees rather than an annual subscription or annual pricing."

"The licensing cost is very expensive."

"The appliance is a bit on the expensive side for the workloads that are not too high."
