� Business processes and the applications that support them are becoming more service oriented, modular in their construction, and integrated.

� The components of these services are implemented on a variety of architectures and hosted on heterogeneous IT infrastructures.

� Approaches to managing these infrastructures along the lines of platform architecture boundaries cannot optimize: alignment of IT with business objectives; responsiveness to change; resource utilization; business resiliency; or overall cost of ownership.

� Customers need better approach: The ability to manage the IT infrastructure and Business Application as an integrated whole.

Information technology today is limited by the technology and architecture configurations available.

Linux no Mainframe



Desenhado para fornecer um gerenciamento eficiente de memória: O z/VM só mantém as páginas de memória que realmente são utilizadas pelas VMs, economizando memória real. Além disso, consegue mover as páginas pouco usadas para o espaço de Page e voltar para a real somente se for necessário.

Maior overcommitment de recursos: o z/VM continua extremamente estável com uma alta utilização dos recursos virtuais, mesmo que a utilização demandada pelos sistemas virtualizados seja muito maior que a de recursos de CPU e memória reais disponíveis.

Prioridade (share) de recursos: no z/VM, é possível reconfigurar dinamicamente qual é a prioridade de uso de todos os recursos (CPU, memória e I/O).
