It is a very cool operating system. I had the pleasure of configuring it (in it’s ibm z/VM form) from scratch a few years ago. However due to company politics it only ran for 2 years. If you are based anywhere in the US you could probably make a career out of it. If you are in Europe I don’t know if it is a wise choice. Not much z/VM there. If you now own a modern mainframe and want to run Linux workload for example I think you are better of using kvm. However if you need to run z/OS virtualised your only option is still z/VM

Believe it or not this operating system is very much alive and kicking in the form of z/VM 7.5 and some of those ancient rituals are still considered normal in that world ;)

Awesome!! Hope to see more companies go this route. I had the pleasure to do something similar for a company(lot smaller scale though)

It was my first job out of university. I will never forget the awesome experience of walking into the datacenter and start plugging cables and stuff

Or ask my colleague who is zos sysprog to run it on our own ;)

Or just run on zlinux

Lol, big question is would it work on zOS as well.

Firstly I never knew Loc records existed… interesting to read something like this.

Secondly I think cloudflare will see an (sizable???) increase in Loc records due to this article

Shame it is running ms sql. anything Postgress, oracle or db2 and it might have been a candidate for running on a IBM Linuxone might even be a valid contender for the cost it is currently running at.

Only for Linux guests. It is also possible to run kvm

I also think most cloud providers are at least a vendor lock-in and maybe a proprietary nightmare. This way you at least got your own iron and ibm comes to fix parts when they break. (Without disabling your system)

I do agree it is debatable whether it is beter than x86 most of the time cost savings projected when using a LinuxOne it is based on licensing. In the past oracle licenses where per core and we did a project where 8 ifl’s replaced 140 x86 cores

I worked on multiple LinuxOne systems. You can run z/vm and pr/sm. it will also run kvm if you like.

Power consumption (of our box z13 based)is 3kwh regardless of configuration (give or take) but also consider you need a lot less san switches and networking switches to achieve the same goal as a large rack of individual servers

Could be interesting. Some kind of opensource zOS parallel sysplex or zVM single system image. Shame that the last update was done in 2010. Any other known alternatives?

You use it in an environment where you need an extreme level of data integrity and availability. Think banks, airports, government, etc.

Due to io offloading to co-processors and a whole range of supporting cpu types you can set up a system which can handle thousands of transaction per second. Most of the application that are used on mainframe's are databases or message que's

Recently there is an increased interest in running Linux on mainframe's something which can be done since early 2000 you get the benefits of high available and secure hardware and the relative ease of Management of Linux. Another benefit is that you don't really need to train personnel in more exotic operating systems like z/OS.

Most commonly z/OS, z/VM as a hypervisor or just native Linux(rhel, sles, Ubuntu or Debian)

Depending on what model of mainframe you got you can use up to 60 logical partitions which are firmware level virtual machines. and can extend this functionality using z/VM or just plain KVM in a Linux environment

I see dev-ops as a way a company has shaped its delivery process. This means a devops profession does not exist. In short it means that a developer has direct contact with an operator and tester or viceversa. Dev-ops focusses on short direct comunication which has nothing to do with technology or platform (like AWS Cloud, Azure or Google Cloud)

However technology can be used to enhance the devops delivery process. Tools like Puppet, Chef, Docker/Kubernetes can have a positive effect.

To give an answer to your question: no devops is not dead. It is a way to work.
