Agenda

• Overview (30 min)

• Lab (120 min)

• Q/A

What is Cloud Computing

#CitrixSummit

What is Cloud Computing?

• IaaS○ Software, Firewalls, Load Balancers, Servers,

Hypervisors, Storage, Network

• Sold on demand ○ Like a utility (electricity)

○ Paid for by the minute or the hour

#CitrixSummit

What is Cloud Computing?

• Private or Public

○ A private cloud is a proprietary network for a limited number of people

○ A public cloud sells services to anyone on the Internet

○ A hybrid cloud is a composition of the two

Private Cloud Public CloudHybrid Cloud

#CitrixSummit

Challenges with IaaS

• Scalability

• Multiple virtualization platforms

• Storage configuration

• Network requirements

• Complexity

#CitrixSummit

What is CloudStack?

• CloudStack is a Cloud

Orchestration Platform

#CitrixSummit

CloudStack Features

•Multiple hypervisor support

•Scalable infrastructure management

•Automatic configuration management

•Graphical user interface

•Standard API support

Who uses CloudStack?

#CitrixSummit

Who uses CloudStack?

CloudStack Architecture

#CitrixSummit

Architecture is highly scalable CloudStack hierarchical structure can scale to manage tens of thousands of physical servers

#CitrixSummit

• A CloudStack installation consists of two parts:

○ The Management Server

○ The cloud infrastructure that it manages

CloudStack Architecture

ManagementServer

#CitrixSummit

Management Server

Management Server

• Servers, network & storage

• Attached to CloudStack controllers

• Add Orchestration Engine

• Add Business Logic

• Add UI and API

• Add MySQL Database

#CitrixSummit

Cloud Infrastructure - Host

• A host is a single computer

• Hosts provide the computing resources

that run the guest virtual machines

• Each host has hypervisor software

installed to manage guest VMs (x Bare

metal)

• The host is the smallest organizational

unit within a CloudStack deployment

#CitrixSummit

Cloud Infrastructure - Cluster

• A cluster is a group of identical hosts

running a common hypervisor

• Each cluster has a dedicated primary

storage server

• A cluster could be a XenServer pool

• Virtual machine instances can be live-

migrated from one host to another within

the same cluster

PrimaryStorage

VM

#CitrixSummit

Pod

Cloud Infrastructure - Pod

• Typically a pod is a rack

containing one or more

clusters, and a Layer 2 switch

• Architecture is shared by all

clusters in that pod

#CitrixSummit

Cloud Infrastructure - Zone

• A zone consists of one or more pods

• Plus secondary storage

• Often corresponds to a single

datacenter

• Organizing infrastructure into zones

provides physical isolation and

redundancy

SecondaryStorage

#CitrixSummit

Cloud Infrastructure – Primary Storage

• Unique to each cluster

• Stores the disk volumes for all the cluster’s

VMs

• A critical componentoShould be built on high performance hardware

• Shared storage is normally recommended○NFS

○iSCSI

○Fibre Channel

• However, some situations use local storage

#CitrixSummit

Cloud Infrastructure – Secondary Storage

• Stores:oTemplates - OS images used to create VMs

oISO Images

oDisk volume snapshots (saved copies of VM data)

• Available to all hosts in the zone

• Can be replicated to other zones to provide

cloud wide common storage

• Must be NFS○Or NFS + Swift

○Assures availability to all hosts in the datacenter

The Lab Environment

#CitrixSummit

• Our lab uses just one XenServer• The XenServer runs:

○A student desktop server ○A CloudStack Management Server○NFS Server○Two virtual XenServers○Advanced networking
