Why Not Just Virtualization?
Challenges in a Virtualized Environment Multitenancy support How to securely segment resources by user
organization Controlling VM sprawl Pricing resources to shape user behavior Self-service provisioning Avoiding the IT provisioning bottleneck
How do you accurately charge users for their resources todiscourage the notion that VMs are free resources?
Can different organizations compete for the same resources?
Can VMs from different organizations see each other?

Users
Can we have a defined catalog of VMsfor user self-provisioning while ensuringsome level of control?

Change in the way we Manage things
vSphere was traditionally the management layer Did not matter if vCenter was down for maintenance before
With vCloud Director vCenter is more Application Layer Much of the eco-system interfaces with vCenter
vSphere administrators may not be vCloud Administrators vSphere lockdowns (Dos and Donts)
Orchestration and customization may be important Approvals and other workflows
High availability of all components involved vCenter Heartbeat Database Log Shipping FT on vShield Manager

What are Allocation Models?
Definition Allocation Models define how resources are allocated to an
organization Allocation is actually the creation of a resource pool subordinate to the
provider vDC object (cluster or resource) in vSphere
Usage Allocation Models are chosen and set on a per Org vDC basis Type and settings dictate how resources are taken out of the Provider
vDC backing the Org vDC All reservation settings, such as guarantee percentage, will commit
them and take from the available pool Not understanding how these are configured can cause some
challenges

What are the different Allocation Models?
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
Pay As You Go
No upfront resource allocation in the org vDC Resources are reserved as users create vApps
Can set a percentage of resources to be reserved vCPU rating can be adjusted
Allocation Pool
(Virtual container)
Allocated pool of resources with a percentage reserved Cloud admin controls ability to overcommit resources Users cannot modify VM reservations and limits Resources can be shared between org VDCs
Reservation Pool
(Physical container)
Allocated pool of resources with 100% reserved Users can adjust VM reservations and limits No sharing of resources with other org VDCs Similar to allocation pool, with reservation = 100%

Design Considerations (vCAT 2.0)
Provider vDC Should Map to Cluster Level
Minimizes Resource Pool Nesting Prevents Sibling Rivalry
Models affect Resource Pools and VMs differently Pay as you Go: Sets limit on all Virtual Machines Reservation Pool: Sets limit=reservation on Resource Pool Allocation Pool: Sets Limits and % Reservation on Resource Pool
as well as on all Virtual Machines MEMORY only
Allocation Model = Organization vDC When defining an Org vDC you are selecting the allocation model

Networking Layers
3 Different Layers of Networking External Organization vApp
Managed at two layers: Consumers & Providers
An External Network is a network that is outside of VMware vCloudDirector.
This is set up by the Cloud Admin/Provider
An Organization Network is contained within an organization.
This is also set up by the Provider
vApp Network is a contained within a vApp. This is set up by Consumers
Note: Both organization networks and vApp networks are entirely within VMware vCloud Director-managed infrastructure.

Network Pools: Overview
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
Do not have to be VLAN isolated (but recommended for L2 isolation) 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

Network Pools: Portgroup-backed
Requires
Preconfigured portgroups at the vSphere layer Assign meaningful names so its obvious what is being mapped If using vSS portgroups, they must exist on all ESX/ESXi hosts in the cluster
How it works System administrator manually creates the portgroups
When creating the network pool, you are given a list of unused portgroups thatexist in the cluster Advantages
Works with all types of vSwitchesDisadvantages
Requires manual work or orchestration to create all of the portgroups Portgroups needs to be keep in sync on a vSS To ensure isolation portgroups rely on VLANs for L2 isolation

Network Pools: VLAN-backed
Confidential32
Requires A vDS thats connected to all ESX/ESXi hosts in your cluster A range of unused VLANs
How it works vCD admin creates the network pool and chooses an Organization vDS to attach it to,
then provides a range of valid VLANs, for example, 10 15 When an isolated network is needed, vCD will automatically create a portgroup on the
vDS and assign it one of the unused VLAN numbers Many isolated portgroups can coexist on the same vDS because they are isolated by the
VLAN tag
Advantages Isolated networks Best network performance
Disadvantages Requires VLANs to exist in the physical network hardware (physical switches) VLANs are limited and may not be available at all Not compatible with Cisco Nexus 1000V
Use portgroup-backed network pool of portgroups that happen to have VLAN tags

Network Pools: vCloud Network Isolation-backed
Confidential33
Requires A vDS thats connected to all ESX/ESXi hosts in your cluster
How it works: vCD creates an overlay transport network for each isolated network to carry encapsulated
traffic Each overlay network is assigned a Network ID number Encapsulation contains source and destination MAC addresses of ESX/ESXi hosts where VM
endpoints reside as well as the Network ID ESX/ESXi host strips the vCD-NI packet to expose the VM source and destination MAC
addressed packet that is delivered to the destination VM
Advantages: Does not have to use VLANs (can optionally set a VLAN ID for the transport network; leaving
blank defaults to 0)
Disadvantages: Small performance overhead due to encapsulation (dvFilter) runs at around 1% CPU utilization Added MAC header require an increase in MTU same as in MPLS networks vCD-NI is for layer 2 adjacency and not for routed networks vCD-NI is only for VMs and cannot be accessed by physical hosts

Customer Networking Use Case Requirements
Catalog Items need to have static IPs that cannot be changed
(Static IP Pools will NOT be Used) Multiple levels of Testing are required (Org Isolation) Developers need their own isolated space
Ideal for vApp Networking
1:1 NATs will be required for external systems to access VMs Web Services HP-UX Databases Code Repository
Multiple External VLANs will be needed per Org At least 4 Organizations initially will be needed
