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

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

"IBM is a huge organization in comparison to most of the competition, it has massive development and offers very high-quality products."

"The solution is stable."

"IBM DataPower Gateway has positively impacted my organization by allowing me to implement rate limits on the different API usage, which is the benefit."

"Anybody can use it as their security device and as their multi-protocol handling device."

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

"It is a scalable solution."

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

More IBM DataPower Gateway pros

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

"One of our clients is a signature company and developed on a classic Java enterprise application using OpenESB, and in one year they saved £20,000,000 on development and maintenance."

"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."

"Millions of people were connecting every month on the system and there were no issues."

"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 core is very stable."

"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."

Cons

"New users just starting with this product find it a little complex or difficult to use, compared to other products such as AWS."

"For the workloads that are not too high, appliance is a little bit expensive, especially in the development test and UAT environment, where we can use the virtual version of the product."

"API management launched two years back and we consider it quite unstable because we still face a lot of bugs."

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

"The customization of the solution isn't as straightforward as we would like it to be."

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

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

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

More IBM DataPower Gateway cons

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

"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."

"The documentation needs to be better — maybe they could add more accurate tutorials."

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

"The documentation needs to be better."

"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."

Pricing and Cost Advice

"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."

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

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

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

"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."

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

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

"The licensing cost is very expensive."

More IBM DataPower Gateway pricing and cost advice

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

"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."

"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."
