Standardized our Java estate and have reduced licensing costs while maintaining strong support
Azul Zulu's ability to allow us to standardize our Java estate on a single and well-supported platform stands out as one of its best features. This standardization simplifies our compliance audits and ensures all our applications receive timely security updates.Azul Zulu positively impacts our organization by providing a platform that allows us to standardize Java on a well-supported platform. Without the high cost associated with other proprietary vendors, Azul Zulu provides an excellent platform for running our applications.

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

"We achieved specific outcomes from using Azul Zulu by reducing our Java licensing and support costs by approximately 70% when compared to our previous Oracle contract."
"We've had no issues with stability."
"It is a scalable solution."
"DataPower Gateway is a perfect product, and I would recommend using it because it provides a lot of benefits."
"Its initial setup was straightforward."
"Anybody can use it as their security device and as their multi-protocol handling device."
"The product's most valuable features are AAA policies and security features."
"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."
"I like the API Gateway feature."
"You don't have to have a separate DMC proxy because DataPower Gateway is an appliance and will take care of a lot of security features. These include data validations, encryption, as well as XML or any type of scripting or security threats that are present."
 

Cons

"It needs a better update daemon. At this time the process is manual and could be an issue on multiple desktop deployments."
"Improvements for Azul Zulu could include more automated tools for unused code visibility integrated directly into the standard portal to help further optimize our cloud footprints."
"The two biggest issues of this solution are the complexity and the maintenance procedures."
"I noticed that the Gateway Script libraries could be improved, as they are not covering everything I need."
"The product should be more adapted to the DevOps process."
"Small and medium-sized companies might look for cloud-hosted applications due to the cost."
"My experience with the pricing of this product is that pricing is too high and should be reduced."
"Some pre-packaged connectors for integration with various applications, such as SaaS offerings, would be a useful addition."
"One area that could be improved is the integration with Postgres and SQL databases. Currently, IBM DataPower Gateway only integrates with Oracle databases."
"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."
