4.2.1 I/O Controls
vCloud Director offers controls to guard against the misuse of resources by consumers. These include:
*Quotas for running and stored virtual machines determine how many virtual machines each user in the organization can store and power on in the organization's virtual datacenters. The quotas specified act as the default for all new users added to the organization.
*Limits for resource-intensive operations prevent them from affecting all users in an organization and provide a defense against denial-of-service attacks.
*Select the number of simultaneous VMware Remote Console (VMRC) connections to limit the number of simultaneous connections for performance or security reasons.
