Distributed virtualization management from big iron
This paper explores how virtualization muddies the waters for systems administrators. It outlines why systems administrators are wrestling with the issues of heterogeneous virtualization administration, virtual image sprawl, and connecting virtual image deployment to business service management workflows with disconnected tools that are ill-suited for these challenges. It also discusses how IBM is evolving its management solutions to enable heterogeneous virtual server management in a consistent manner (regardless of the virtualization or physical platforms) and the benefits of leveraging Linux on System z as the management platform.
"Enterprises are aggressively using virtualization to consolidate their Windows, Linux and Unix infrastructure and develop new composite SOA-based applications. This consolidation however does not mean the end of enterprise infrastructure heterogeneity since enterprises are also showing a propensity for acquiring different hypervisors. While VMware remains dominant in the datacenter, adoption of other forms of virtualization, such as Microsoft's HyperV, Linux's Xen and Linux on System z, is growing. As a result, several different forms of virtualization are now in use in the datacenter." "These different forms of virtualization provide enterprises with much more flexibility on how to allocate physical resources to applications and workloads, and with much faster speeds for deploying new virtual machines and images. However, these multiple forms of virtualization have introduced more complexity to an already difficult datacenter environment." Virtual image sprawl is problematic due to disconnected tools that are ill-suited for these challenges. So what is IBM doing about it on its platforms?
