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 recommend this solution; it is a good security application and it incorporates integrations and the latest security controls that are available in the market."

"My company has a good impression of IBM DataPower Gateway. What I like about it is that because it's an appliance, it's a turnkey solution that's very fast and out of the box. Compared to other gateways, I also like that IBM DataPower Gateway is function-rich. For example, for one of the projects, there was a need for specific transformation and security features available in IBM DataPower Gateway out of the box, so my team just needed to configure the appliance. There was no need for separate development, and I found it quite neat. Another valuable feature of IBM DataPower Gateway is that it's easy to integrate with other products."

"It is a scalable solution."

"The product's most valuable features are AAA policies and security features."

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

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

"The appliance has great security and reliability."

"The solution was very stable, we had no issues with it in that sense, it didn't crash or freeze and there were no bugs or glitches."

More IBM DataPower Gateway pros

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

"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."

"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."

"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."

Cons

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

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

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

"This solution is not scalable for our environment."

"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."

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

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

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

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. 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."

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

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

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

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

Pricing and Cost Advice

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

"The licensing cost is very expensive."

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

"It is an expensive solution."

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

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

"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."

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."
