计费功能 - vCenter Chargeback
Account, monitor, and report on costs associated with your virtual infrastructure
优点 Benefits
• Improve Resource Utilization: By associating costs to VM’s many of the
“free” VM’s will go away, freeing up resources for higher priorities
• Optimization of Budgets: Business units can understand how much they
are paying for resources and how much goes to unused, allowing them to optimize resource consumption & costs
主要功能 Key Features

6、说明异构虚 构虚拟化技 技术生成的虚拟服务器的互通和兼容程度， 的 通和兼容程度 实现 实 互通和兼容的思路是如何？
OVF std. The Open Virtual Machine Format (OVF) specification is a hypervisor-neutral, efficient, extensible, and open specification for the packaging and distribution of virtual appliances composed of one or more VMs. It aims to facilitate the automated, automated secure management not only of virtual machines but the appliance as a functional unit. For the OVF format to succeed it must be developed and endorsed by ISVs, virtual appliance vendors, operating system vendors, as well as virtual platform vendors, and must be developed within a standards-based framework.


vApp Overview
vApps are multi-tier application services that you can manage as a single inventory item. • Provides for single-step management vApp • Eliminates complex setup
and configuration

“VMware致力于开放标准，我们非常高兴将VMware vCloud API提 交至DMTF。

VMware vCloud API提供了诸如vApps、网 网络、虚 虚拟数 据中心的上传、下载、示例、部署和运行这样的功能，我们认为它将成 为开启流程标准化的重要基础。

我们的最终目标是在提供云交互性的 同时，帮助厂商 帮助厂商为自身客户提供具有显著差异性的价值。
