Yourown cloud?

摘要

Rather than going to Multiple software-as-a-service (SaaS) providers to host your applications, VMware Inc. wants you to build a private, cloud-like infrastructure in your own data centre. But with the in-house skills and costs required to make it happen, virtualization experts argue that VMware's vision is far away from becoming a reality. Last September, the virtualization giant unveiled Virtual Datacenter OS, a set of services that allows IT managers to "pool all types of hardware resources - servers, storage and network - into an aggregated on-premise cloud," according to the company. This will enable users to abstract the underlying physical infrastructure from the applications and give VMware customers the ability to offer SaaS on their own premise.
