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.

23. 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).
Algumas vantagens do z/VM
