VMware vCloud Director is a cloud computing platform that provides Infrastructure as a Service. It abstracts and federates VMware vSphere resources to enable highly scalable and elastic provisioning of compute, storage, and network resources as virtual machines to users on demand. Key features include self-service provisioning, resource pooling and allocation, network segmentation and isolation using vShield Edge, and automation.

4. Cloud Computing Has Many Definitions – This is VMware’s
Cloud Computing is an approach to computing that leverages the efficient pooling
of on-demand, self-managed virtual infrastructure, consumed as a service.
Efficiency thru Utilization
Agility with Control Freedom of Choice
and Automation
Pooling Self-Service Open and Interoperable
From machines to highly Easy access with policy- Application mobility between
elastic resource pools, with on- based provisioning and clouds, based on open
demand capacity deployment standards
Zero-Touch Infrastructure Control Leverage Existing
Policy-driven automation of Application-aware Investments
provisioning, deployment and infrastructure with built-in Benefits of cloud computing to
management availability, scalability, security existing applications and
and performance guarantees datacenters

10. Resource Allocation
Resource Allocation Models for Organization vDCs
• Allocated sub-resources of a provider vDC
• Allocation uses a model, each of which can set limits on number of VMs
Allocation Model Definition
Pool expands to accommodate
• No upfront resource allocation in the org vDC resources reserved on demand
• Resources are reserved as users create vApps
Pay As You Go vApp
• Can set a percentage of resources to be reserved
vApp
• vCPU rating can be adjusted
Partially reserved pool of resources
• Allocated pool of resources with a percentage reserved
Overcommit
Allocation Pool • Cloud admin controls ability to overcommit resources Range
Guarantee
(“Virtual container”) • Users cannot modify VM reservations and limits
Actual
• Resources can be shared between org VDCs
Fully reserved pool of resources
• Allocated pool of resources with 100% reserved Guarantee
Reservation Pool • Users can adjust VM reservations and limits
(“Physical container”) • No sharing of resources with other org VDCs
• Similar to allocation pool, with reservation = 100% Actual

11. Network Resource Requirements
Networking Requirements
• External Networks – Connectivity outside a cloud
• Organization – Connectivity for VMs of the same organization within a cloud
• vApp – Connectivity for VMs within a single application
Manage at two layers: Consumers & Providers
Network Segmentation and Isolation
Automated Provisioning
Note: Both organization networks and vApp networks are entirely
within VMware vCloud Director-managed infrastructure..
11

12. Network Resources (External Networks)
a.k.a ‘Provided Network’
• Network that is external to VMware vCloud Director
• Created in vSphere and consumed by VMware vCloud Director to provide
external connectivity to Organizations
• Mapped to a portgroup at the VMware vSphere layer (vSS or vDS)
• The portgroup is attached to VMware vCloud Director as an “External Network”
Use cases
• Internet access
• Provider supplied network endpoints
• IP based storage
• Backup servers Set up by Provider
• Backhauled networking to a customer datacenter
• VPN access to a private cloud
• MPLS termination
12

13. Network Resources (Organization Networks)
Contained within an organization
Allows vApps within the organization to communicate with each
other or to outside the organization
Can be connected to External Networks as:
• Public (External Org Direct)
• Bridged connection to an External Network
• Others outside the organization can see
• Private Routed (External Org NAT-Routed)
• Connected to an External Network through a vShield Edge
• Can be configured for NAT & Firewall
…or left unconnected to external Set up by Provider
• Private Internal (Internal Org)
• No External connectivity
Backed By Network Pools
13

14. Network Resource (vApp Networks)
Contained within a vApp
• Inherently Private Internal
Allows VMs in a vApp to communicate with each other
or...by connecting them to Org Networks, other vApps
Can be connected to Org Networks as
• Public (Direct)
Set up by Consumers
• Bridged connection to a organization network
• Private Routed
• Connected to a organization network through a vShield Edge
• Can be configured for NAT & Firewall
Backed by a Network Pool
14

15. Network Resource (Network Pools)
A set of pre-configured network resources that can be used for
Organization and vApp Networks
• Use to facilitate VM to VM communication
Three Types of Network Pools in VMware vCloud Director
• Portgroup-backed
• Reference pre-created portgroups
• These have to be created in vSphere manually or through orchestration
• Typically associated with different VLANs
• Attach a collection of them to VMware vCloud Director
• VLAN-backed
• Exactly like portgroup-backed…but VMware vCloud Director will automatically
create the portgroups as needed, and use a range of VLANs to isolate them.
• vCloud Network Isolation-backed (vCD-NI)
• VMware proprietary network isolation technology
