The IBM DataPower Gateway is a security and integration platform.
IBM Cloud Pak for Applications is clearly suitable for modernizing the WebSphere runtime from the heavy, complex and expensive WAS-ND, and to a lesser extent WAS-base, to the super simple, fast and lightweight WebSphere Liberty runtime. I guarantee, once you start using Liberty you'll never look back. Enough cannot be said about how awesome Transformation Advisor is. The output analysis it produces, along with the migration plan and associated artifacts, considerably simplifies both the decision-making process surrounding modernization and subsequent implementation. Without TA we would've made bad decisions by blindly picking unsuitable apps for moving from WAS to Liberty. Using the results from TA we've excluded multiple WAS apps from our immediate plans to migrate to Liberty, saving time and effort that probably would have resulted in a failed migration. We recently used Transformation Advisor to help us successfully migrate an app from Tomcat to WebSphere Liberty. We needed to make some changes to the Tomcat app, but TA helped highlight these required changes. Without TA I'm not sure we would have succeeded.
WebSphere DataPower Gateway is really beneficial if you are trying to integrate two or more systems. It provides you with comfort and peace of mind by creating a DMZ zone for the services which are going out of the intranet to hit external clients APIs. It is greatly recommended if you have a very high volume service or API which is being used by a majority of clients because it has a dedicated physical box present which takes care of memory, CPU and all such stuff. So, all your transactions happen at wire-speed.
The most obvious thing that DataPower does exceptionally well is security. All the built-in supported security capabilities allow us to isolate most security tasks to DataPower and as a result "protect" down steam services/systems to have to deal with security.
DataPower is very good at protocol conversion and as it is usually used on the edge allows you to narrow down the protocols used between the companies public and private networks.
The appliance concept makes maintenance, recovery and, management so much simpler.
While the licensing is considerably simplified than it used to be, I still find it somewhat confusing. For example, WebSphere Liberty Core has an 8:1 VPC ratio. This is clear when dealing with VMs but it is still not clear to me as to whether we get an 8:1 ratio when running on OpenShift or whether we need to purchase additional OpenShift licenses to support running WebSphere Liberty Core in OpenShift.
Not so much related to IBM Cloud Pak for Applications, but while Transformation Advisor is an indispensable tool to help modernize to the WebSphere Liberty runtime, I wish we could run it against WebSphere Liberty itself. The reason being, we are now using TA as a single repository for our configurations. TA also highlights many potential issues when migrating to Liberty; these issues may also be applicable for apps already running in Liberty, we just don't know it yet.
The old interface is being really missed by our team as the new WebUI interface is not that intuitive or easy to work with. It takes a lot of time to load. There should be an inbuilt wizard for creating a Rest service as well like there is for an XML based service.
IBM support is very knowledgeable but it's not that easy to reach them. They don't release the fix patches very soon which also becomes a big issue in certain situations where critical projects are involved.
Lastly, DataPower has its steep learning curve and it requires time and effort on your end to gain full control and make the most of the advanced features which it offers. Finding the right resource in the market is not that easy.
Comparing IBM Cloud PAK for Applications against alternatives highlights its distinct advantages. Its robust support for hybrid and multi-cloud environments enables unmatched flexibility in application deployment, crucial for businesses seeking to leverage various cloud services. This contrasts with platforms that may limit their focus to a single-cloud approach or offer restricted multi-cloud capabilities.IBM Cloud PAK's seamless integration with AI and data analytics, particularly through IBM Watson, provides powerful tools for developing AI-driven applications. This integration is a key differentiator from competitors that might not offer as comprehensive AI and analytics tools, allowing businesses to easily incorporate advanced technologies into their applications.Furthermore, IBM Cloud PAK for Applications prioritizes ethical AI development and compliance with regulatory standards, aligning with OpenAI’s guidelines. This commitment is essential for organizations that value responsible AI practices and need to adhere to strict privacy and security regulations.The selection of IBM Cloud PAK for Applications was driven by its holistic approach to application development, offering a blend of flexibility, advanced technological integration, and a commitment to ethical standards, making it a superior choice for businesses focused on innovation while adhering to ethical and legal standards.
We have been able to migrate apps away from the expensive WAS-ND to the more cost-effective WAS-base without throwing away our WAS-ND licenses. With a 1:4 ratio of WAS-ND to WAS-base we've been able to we've been able to save in excess of 75% on licensing charges for these apps.
By having a license model based on VPC ratios (1:4:8 - WAS-ND:WAS-base:Liberty core) we've been able to move away from using license pooling resulting in over-allocating (i.e. wasting) CPU cores for each license pool, to using consolidated license pools hosting a combination of WAS-ND, WAS-base and Liberty-core. This has allowed us to reduce our licensing costs accordingly.
It has really taken our business to the next level. We have expanded and integrated with so many new vendors and for all those integrations DataPower is serving as our security gateway.
We don't have to depend on any other tool for doing the load balancing of the incoming requests as that is also taken care inside the WebSphere DataPower Gateway box itself, thereby distributing the load equally.
It has made our platform much more secure, uniform and robust to deal with any kind of incoming message format or threat as well due to its latest security mechanisms and huge processing power.
