I, too, have seen the kinds of studies you mention that point to increasing interest in Linux on System z and I'm the first to point out the unscientific nature of our poll. What do you make of the new Linux-based mainframe from IBM? I started a new thread about that over here, but I certainly won't object if you want to answer on this thread.
Thanks for speaking up! To answer your question above effectively it really depends on what the initial goals are in moving to Linux on the mainframe. Certain workloads and applications are better candidates to move to Linux. I read an interesting blog yesterday from Marcel Hartog. He argues that, while mainframers understand that the mainframe is perfectly suited for use in a cloud, the only way those outside the mainframe world will understand that is if mainframers demonstrate it to them.
Naturally, his words are better than mine--you can read the whole post here , but here's an excerpt: Everybody wants "cloud".
And at the time we are telling other mainframers how good the mainframe is, the "Blade people" are building clouds. They are demonstrating to Architects and IT Management how easy it is to run 12 images on 2 or 3 physical boxes and they demonstrate it as a mini-cloud.
More a puff of smoke, but the architects and your IT Management sees "Cloud" in action. And they like what they see. So the architects start making plans to build the next generation IT Infrastructure.
And in these plans, I do not see the "Z" word Believe me, I see it happen around me So let's stop talking. Fire up some Linux and demonstrate that you can run the same stuff as "they" can. More flexible, more efficient, more powerful and better managed. Demonstrate that you CAN get 20 year old virtualization techniques to work for your company. Demonstrate value The tools to manage the virtualized environment are available, so that should not stop you I've started a new thread where we can discuss what the adoption of cloud computing means to the future of the mainframe.
Check it out and add your thoughts here. We are looking at Linux on z as a server consolidation play. The only problem is, that commodity servers are so much less expensive than the mainframe in terms of acquisition cost. It is difficult for management to look beyond that to what the fully loaded environment costs to run and maintain. Compared to commodity servers running Linux however, not so much. The Linux on z Solution Edition seems to be setting the playing field a lot more level.
However, many challenges remain. I'd be interested to know if any companies successfully moved all or part of their commodity server infrastructure running Linux to Linux on z - and if so, whether overall cost was a factor. Hi StevenWe have a few examples of customers who have indeed moved a large portion if not all of their environments over from Linux in a distributed environment to Linux on System z.
In some customers llike Nationwide and Dundee Council customers do indeed chose to keep some workloads on x86 platforms while leveraging the benefits of Linux on System z for other workloads. While costs are often a key driver for making the move from a distributed environment to Linux on System z other factors play a role in deciding to move workloads to Linux on System z. Cloud migration projects are happening in virtually every large enterprise throughout the world, and in many small and midsize companies as well.
For most, cloud data migration is an ongoing journey, For organizations running IBM Z mainframe systems, several converging trends in recent years have made it more challenging than ever to achieve the needed organizational performance at the best Virtually everything in your business depends on IT running smoothly.
For most enterprises, service outages result in lost productivity, missed opportunities for revenue, and sometimes severe Christopher Tozzi May 10, Share on: LinkedIn Twitter Facebook. A very brief history of mainframe operating systems If you have worked in the mainframe world for decades, you know that mainframes are much older than Linux-based operating systems.

Getting the Most Out of Your Mainframe See how to offload, accelerate and lower cost of your mainframe to maximize its value Read. Linux is essentially a server OS and is supported on a wide range of platforms.
One of the primary benefits offered by Linux is the fact that so many budding developers can easily get their hands on the platform. Mainframe specific development experience can be hard to come by. The decisions between one or the other must be made on a case-by-case basis and the answer may change over time. This means you need an expert in the field that understands your situation and the technology at hand.
