IBM Cloud Pak for Applications vs. Node.js

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.

If you need a fast, robust and reliable server side framework that allows you to write JS on the backend and therefore have your project in one language - Node.js is a stand out choice. It can easily handle heavy traffic on very little resources (CPU and memory usage is very efficient). I can't recommend it enough, it is such a pleasure to work with - I feel it gave me back my career. I was so bored with the banality of .NET, I had also come to dislike it's overly convoluted and complicated class structure. Node.js was the fresh start I needed, it can be as simple or as complicated as you like - but even at it's most complicated it can still beat the pants off .NET core any day.

• Node.js using V8 engine that allows run both UI and server side using JavaScript.
• Eliminates waiting time.
• Cross-platform that can execute different platforms like android, web apps, and other IoT devices.
• Uses Non-blocking property so that can be handled multiple requests with quick response.
• Easy to install and maintained.
• Open source.

• 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.

• Performance bottlenecks need to be profiled and ameliorated.
• The Asynchronous Programming Model has a learning curve which isn't always intuitive to entry-level coders.
• Much more suited to the cloud, as opposed to bare-metal installations.

Node.js is easy and good to use, their support team is also good they always tend to help you, and solve your problem, even we know that Node is free to use and opensource but then also we get support from them but for getting much better results we need to purchase standard or enterprises support provided by them.

Our customer mission-critical core banking applications like Temenos T24 run on best of the breed IBM WebSphere Application Server which is java based-application server. IBM has kept up the promise of providing support, fixpack, and any update. As far as I know, at least by 2030, IBM is committed to continue with WHE which gives customers confidence in their current investments.
