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

"The most valuable features for our business include the ability to monitor and log data transactions and handle multiple request at an enterprise level."

"From a technical point of view, IBM DataPower Gateway performs quite well, so my team had no concerns at all in terms of performance, reliability, and stability."

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

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

"The most valuable features for our business include the ability to monitor and log data transactions and handle multiple request at an enterprise level."

"The support for IBM DataPower Gateway has been exceptional."

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

"For me, its most valuable features include: the fact that it's high-speed, its ability to be remotely administered via an API, the fact that it can deal with multiple protocols, and it's very quick to make changes to the setup."

More IBM DataPower Gateway pros

"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."

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

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

"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 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."

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

"The core is very stable."

Cons

"One area that could be improved is the integration with Postgres and SQL databases. Currently, IBM DataPower Gateway only integrates with Oracle databases."

"Some pre-packaged connectors for integration with various applications, such as SaaS offerings, would be a useful addition."

"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."

"The DCDR process should be less complex."

"Traceability could be improved, especially for business operations."

"The product's cost for data appliances or hardware is quite high. It needs improvement."

"Traceability could be improved, especially for business operations. The traceability of the transactions could be an improvement point for DataPower to work on. It would be better if they provided JSON support. JSON protocol data has changed format. It started performing internal transformation to JSONx. This might be an additional complexity."

More IBM DataPower Gateway cons

"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."

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

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

"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."

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

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

"The documentation needs to be better."

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

Pricing and Cost Advice

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

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

"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."

"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."

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

More IBM DataPower Gateway pricing and cost advice

"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."

"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."
