as a local repository for content published by another cloud or any Web
site that hosts a VMware Content Subscription Protocol (VCSP)
endpoint.
An organization administrator or catalog owner controls catalog sharing.
Organization administrators in organizations that have permission to
publish catalogs control publication and subscription options for catalogs in
their organization. A system administrator can enable background
synchronization of catalogs with external sources and set background
synchronization schedules to regulate consumption of network bandwidth
by this activity.
Organization VDCs
An organization virtual datacenter (organization VDC) is a deployment
environment for virtual systems owned by the containing organization, and
an allocation mechanism for resources such as networks, storage, CPU, and
memory. In an organization VDC, computing resources are fully virtualized,
and can be allocated based on demand, service level requirements, or a
combination of the two.
Organization VDC
Networks
An organization VDC can be provisioned with one or more networks. These
organization VDC networks can be configured to provide direct or routed
connections to external networks, or can be isolated from external networks
and other organization VDC networks. Routed connections require an Edge
Gateway and network pool in the VDC. The Edge Gateway provides
firewall, network address translation, static routing, VPN, and load
balancing services.
Virtual Systems and
Media Images
Virtual systems and ISO-format media images are stored in a catalog and
represented as catalog item objects. Virtual systems are stored as templates,
using an open standard format (OVF 1.0). These templates can be retrieved
from catalogs and transformed into virtual systems, called vApps, through a
process called instantiation, which binds a template’s abstract resource
requirements to resources available in a VDC. A vApp contains one or more
individual virtual machines (Vm elements), along with parameters that define
operational details, including:
n
How the contained virtual machines are connected to each other and to
external networks.
n
The order in which individual virtual machines are powered on or off.
n
End-user license agreement terms for each virtual machine.
n
Deployment lease terms, typically inherited from the containing
organization, that constrain the consumption of VDC resources by the
vApp.
n
Access control information specifying which users and groups can
perform operations such as deploy, power on, modify, and suspend on
the vApp and the virtual machines that it contains.
Tasks
Asynchronous operations are tracked by task objects. Running and recently
completed tasks initiated by members of an organization are kept on the
organization’s tasks list.
