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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"Since it is a gateway, it provides a lot of security features."

"It is a scalable solution."

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

"Its initial setup was straightforward."

"I like the API Gateway feature."

"The solution is robust."

"The product is stable...The product is scalable."

More IBM DataPower Gateway pros

"The core is very stable."

"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."

"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."

"The process-oriented solution allows you to define choreography and orchestration."

Cons

"DataPower isn't the most user-friendly tool. It is not an easy tool to use. Some things could use better wizards to guide you through processes."

"In terms of OEM support, it is poor. If I raise a CBRT one, as per the SLA, they should respond in one hour, however, sometimes it takes four or five hours to respond."

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

"Small and medium-sized companies might look for cloud-hosted applications due to the cost."

"In the next release, I would like to see the product price reduced. It should be cheaper."

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

"The initial setup isn't so easy, you need who has experience working with the solution to help."

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

More IBM DataPower Gateway cons

"Cloud deployment is weak and needs to be improved."

"Regarding its management, a web console being able to synchronize distributed instances would be great."

"The documentation needs to be better."

"The documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."

Pricing and Cost Advice

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

"This product is a bit expensive as IBM products are costly assets. However, for enterprise customers it is a worthwhile investment."

"The licensing cost is very expensive."

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

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

"The solution is expensive in comparison to other products."

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

More IBM DataPower Gateway pricing and cost advice

"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."

"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."

"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."
