Scalable, flexible and familiar IaaS - IBM Cloud Infrastructure Center 1.1.3 on IBM Z and LinuxONE

Businesses looking to reduce costs, increase agility, and deliver innovation to their customers are turning to cloud for their future IT infrastructure. However, the need to combine this with enterprise IT qualities of service such as security, scalability and reliability is often leading these organizations to deploy private cloud for core workloads and then hybrid cloud to bring together the data center with private and public cloud.

 One approach to these challenges is to build on the well-known qualities of service delivered by IBM Z and LinuxONE – advanced security, vast scalability, and legendary reliability – with the layers of cloud software which in turn can provide the cost benefits, flexibility and business innovation.

 IBM Cloud Infrastructure Center does this on IBM Z and LinuxONE, providing the Infrastructure-as-a-Service (IaaS) layer and enabling private clouds to be built. 

IT administrators can easily provision and manage virtual machines on both IBM z/VM and Red Hat-based KVM, using a familiar OpenStack-compatible API and self-service portal. You can read more about Cloud Infrastructure Center in a blog by IBM’s Jerry Hosch – “Simplified Infrastructure-as-a-Service (IaaS) management for Linux on IBM Z and LinuxONE”

The IaaS layer provided by Cloud Infrastructure Center then provides the foundation for higher levels of cloud management tools, such as the Platform-as-a-Service (PaaS) layer provided by Red Hat OpenShift which includes support for containers and Kubernetes.


What’s new in IBM Cloud Infrastructure Center 1.1.3 

Newly available this year is the latest version of IBM Cloud Infrastructure Center – continuing the themes of scalability, flexibility and familiarity. 

  • Virtual machines can now be resized through the command line or the API – both for z/VM and for Red Hat-based KVM. This increases flexibility for operations teams to automate scalability, allowing virtual machines (VMs) to be expanded or contracted depending on application workload requirements.
  • Live VM migration is now possible for RHEL-based KVM virtual machines which can be moved from one host to another, increasing the flexibility and ability to balance workloads
  • Persistent storage support has been expanded, icluding the ability to boot from both IBM DS8000 storage and IBM FlashSystems

Cloud Infrastructure Center supports provisioning VMs running Linux distributions from Red Hat, SUSE and Canonical – including Red Hat CoreOS images used as part of Red Hat OpenShift Container Platform.


User example – IBM CIO Office

IBM’s CIO Office is using Cloud Infrastructure Center on IBM Z to help it transition from the traditional IT operations model to a cloud operations model, enabling the CIO Office to integrate IBM Z into their hybrid cloud approach.

“IBM Cloud Infrastructure Center allows us to substantially improve our infrastructure management and reduce cost & complexity to manage from simple to complex environments.” commented Eric Everson Mendes Marins, in the PCS_ZVM squad at the IBM CIO Office.


More information

IBM Cloud Infrastructure Center continues to provide an IaaS on IBM Z and LinuxONE, as well as providing a user-provisioned infrastructure (UPI) for Red Hat OpenShift on IBM Z and LinuxONE – enabling IBM Z and LinuxONE to provide an innovation platform for hybrid cloud.
