What do you like best about IBM WebSphere?
WebSphere Hybrid Edition is helping us modernize our WebSphere runtime from 'traditional' WebSphere Application Server (tWAS) to a much simpler, lightweight, fast and easy-to-use runtime in WebSphere Liberty. While tWAS is a great product and has served us well over many years, WebSphere Liberty is better.
WebSphere Liberty is suitable for not only traditional VM environments - where most of our workload is today - but WebSphere Liberty has been purpose-built for the cloud, with super fast startup times and low memory requirements.
And once your transition from tWAS to WebSphere Liberty is complete, should you wish, the next step to containerize your apps is effortless.
Of course, not all apps in their present form are suitable candidates for the cloud. That’s where Mono2Micro comes to the rescue. Mono2Micro helps you refactor your apps to microservices. I will admit that while I have tried the product, and it is pretty impressive with what it did, coming from an admin rather than a development background, I did find it somewhat challenging. Placed in the right hands, though, I could see it considerably simplifying and reducing the risk and effort in this refactoring process. I’m not sure how you could refactor a monolithic app any other way.
Much, if not all, of the complexities of creating and managing tWAS environments are eliminated when using WebSphere Liberty. I cannot stress this enough; you should start using and moving (from tWAS) to WebSphere Liberty today. You won’t look back! If you’re an admin, your app teams will thank you for it. As an admin, creating a WebSphere Liberty server in one second sure beats the manageProfile and addNode commands. Even the ability to rename a WebSphere Liberty server with a Unix ‘mv’ command is a win for me. Or being able to clone an existing server with a Unix copy command saves too much time and effort. Many years back, I had difficulties convincing teams to use WebSphere Liberty rather than tWAS, but now they are asking me for it!
And to help you on your journey, WebSphere Hybrid Edition provides Transformation Advisor (TA), which scans your code to identify the suitability of using WebSphere Liberty, identifies what needs to change, provides an estimate on the effort required and helps generate your server.xml file. TA can also help identify apps using WAS-ND that could run in WAS-base, thereby saving considerably on licensing charges - this is helping us in such an exercise.
Then there’s the complex world of managing licenses. Using WebSphere Hybrid Edition has simplified our licensing model and is helping alleviate our concerns about exceeding our rights. Now we can have one pool, not a WAS-ND pool, a WAS-base pool, and a Liberty core pool. Just one license pool to manage them all.
WebSphere Hybrid Edition has allowed us to convert our expensive WAS-ND licenses to WebSphere Hybrid Edition licenses for a small cost without discarding our WAS-ND licenses entirely. Now we can transition appropriate apps from WAS-ND to WAS-base, Liberty-base or Liberty-core without wasting our WAS-ND licenses and purchasing new WAS-base or Liberty-core licenses. Strange as it sounds, we have several apps using WAS-ND without using any of the WAS-ND features.
And lastly - this is not a sales pitch, just my opinion - I do like IBM’s commitment and investment to making WebSphere Liberty the best product possible, with a particular focus on the cloud. This investment can be seen with what appears to be a fantastic feature in Liberty InstantOn. Review collected by and hosted on G2.com.
What do you dislike about IBM WebSphere?
My least-liked feature isn't easy to answer as there is so much to like about WebSphere Hybrid Edition, particularly WebSphere Liberty. Of all the features of WebSphere Hybrid Edition, while I like Mono2Micro, it was somewhat overwhelming. It should be noted that this is not a reflection on the product - which is quite impressive - it’s more a reflection of the difficulties an admin like me has with the product. As mentioned earlier, I’m sure the feeling would be different in the hands of a developer.
Similarly, nothing to do with Mono2Micro, but I feel WebSphere Hybrid Edition truly shines when moving from tWAS to WebSphere Liberty - this is where the mix-and-match licensing helps - rather than Mono2Micro. Review collected by and hosted on G2.com.
