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

"Its initial setup was straightforward."

"It is a scalable solution."

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

"We are mostly using the IBM DataPower Gateway for security purposes and load balancing purposes."

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

"The solution is straightforward and for large organizations, it functions well."

"I like that it is very stable, and we never experience any downtime."

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

More IBM DataPower Gateway pros

"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."

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

"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."

"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."

"Opens the door to connect modern web products to an old legacy system."

"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."

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

Cons

"For the workloads that are not too high, appliance is a little bit expensive."

"My experience with the pricing of this product is that pricing is too high and should be reduced."

"The components that they include in the product that are, in fact, a WTX, really need to be removed from the product because they tend to fail."

"An area for improvement in IBM DataPower Gateway is its price point because it's a relatively expensive product. Sometimes, when the customer use case is just a very small subset of what's being offered in IBM DataPower Gateway, then the product can be expensive, making my company lose some of the opportunities because of the expensive pricing. A lower price point for IBM DataPower Gateway, even if that results in a less feature-rich version, would be appreciated. In terms of additional features that I'd like to see in the next release of IBM DataPower Gateway, nothing specific comes to mind because IBM constantly improves its standards and provides quarterly updates to the product, so it's quite fine."

"IBM DataPower Gateway is quite big for smaller organizations, looking at different types of clients who are virtually assisted in this, I would say it's not really a good product for smaller firms."

"Scripting needs improvement. It's hard for our customers."

"The solution requires a lot of training manuals in order to get to know it better and to be able to use it effectively."

"They should add features to manage API integrations."

More IBM DataPower Gateway cons

"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."

"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."

"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."

"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."

"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."

Pricing and Cost Advice

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

"The cost is very high and requires all five components in the API management solution."

"IBM DataPower Gateway is quite expensive to get resources to work on this product. If the price could be cheaper, I think that will make it a little bit better and easily accessible to smaller clients. Then it could compete with other solutions that are available in the market. There's a whole lot of other solutions available that work well and are cheaper than IBM's products."

"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."

"It is an expensive solution."

"It's expensive when you compare it with others."

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

"The total cost of IBM DataPower Gateway would depend on the configuration, but in my experience, it can amount to 60,000 Euros per box, even for the virtual version. Usually, customers need high availability and a non-production environment, so the total price for IBM DataPower Gateway can be quite a lot. It can be 200,000 Euros or a similar figure."

"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."
