What Is CloudStack?

CloudStack™ is a software platform that pools computing resources to build

public, private, and hybrid Infrastructure as a Service (IaaS) clouds.

Use to :

Deployment

Management

Configuration

Manage :

Network

Storage

Computer Nodes

Make up a

Cloud Infrastructure

What Can CloudStack Do?

Multiple Hypervisor Support

Massively Scalable Infrastructure Management

Automatic Configuration Management

Graphical User Interface

API and Extensibility

High Availability

Cloud Concepts

Management Server Overview :

Provides the web user interface for the administrator and a

reference user interface for end users

Provides the APIs for CloudStack Platform

Manages the assignment of guest VMs to particular Hosts

Manages the assignment of public and private IP addresses

to particular accounts

Manages the allocation of storage to guests as virtual disks

Manages snapshots, templates, and ISO images, possibly

replicating them across data centers

Zones

A zone is the largest organizational unit within a CloudStack deployment. A

zone typically corresponds to a single datacenter, although it is permissible

to have multiple zones in a datacenter.

Pods

A pod often represents a single rack. A pod is the second-largest

organizational unit within a CloudStack deployment.

Clusters

A cluster provides a way to group hosts. The hosts in a cluster all have

identical hardware, run the same hypervisor, are on the same subnet, and

access the same shared primary storage.

Hosts

A host is a single computer. Hosts provide the computing resources that run the guest

virtual machines.

Primary Storage

Primary storage is associated with a cluster, and it stores the disk volumes for all the

VMs running on hosts in that cluster.

Secondary Storage

Secondary storage is associated with a zone, and it stores the following:

Templates - ISO images - Disk volume snapshots

Physical Networks

Part of adding a zone is setting up the physical network. Each physical

network can carry one or more types of network traffic.


Part 2

How to Build a Cloud ?

1) Supply and installation of the required hardware

2) Connect to Free Internet

3) Install the required software

4) Testing and Use

Start Installing the Cloudstack

Operating System :

• CentOS/RHEL 6.3+ 64-bit

• Ubuntu 12.04 (.1) 64-bit

Cloudstack :

• Apache Cloudstack 4.0.1

• Citrix Cloudstack 3.0.2

Hypervisor Hosts

VM App :

Getting the Release

Download the latest CloudStack release from the

Apache CloudStack

Verifying the downloaded release

Getting the KEYS

# gpg –-import KEYS


Prerequisites for building Apache CloudStack

Ant 1.8.4

Tomcat 6.0

Maven 3.0.4

Java (Java 7/OpenJDK 1.7)

Rpmbuild or dpkg-dev


Building RPM

We can resolve the buildtime depdencies for

CloudStack by running the following command:

# mvn -P deps

we can move on to building CloudStack and packaging

them into RPMs by issuing the following command:

# ./waf rpm


Configuring your systems to use your new yum repository

We will create yum repository a file at /etc/yum.repos.d/

cloudstack.repo

[apache-cloudstack]name=Apache CloudStackbaseurl=http://cloudstack.apt-get.eu/rhel/4.0/enabled=1gpgcheck=0


The procedure for installing the Management Server is:

Prepare the Operating System

Install Management Server

Install and Configure the MySQL database

Prepare NFS Shares

Prepare the System VM Template


Before Starting with Cloudstack

Service mysqld start

Service ntpd start

Service iptables start

Service nfs start

Service rpcbind start

Service cloud-management start

Cloud-setup-management

Installation Complete!

MySQL

cloud_db

Management

ServerUser Interface


Citrix XenServer Installation for CloudStack

Configure XenServer dom0 Memory from 726MB to 2940MB

Set username and password

All XenServers in a cluster must have the same username and password as

configured in CloudStack.

Time Synchronization

Getting and Deploying a License


Citrix XenServer Installation for CloudStack

From https://www.citrix.com/English/ss/downloads/,

download the appropriate version of XenServer for your

CloudStack version

Install XEN Server as Operating System Base on VM Host

Installation Complete!

MySQL

User Interface

Log In to the UI

CloudStack provides a web-based UI that can be used by

both administrators and end users.

The UI is available in popular browsers including IE7, IE8,

IE9, Firefox 3.5+, Firefox 4, Safari 4, and Safari 5.

The URL is:

http://192.168.50.1:8080/client

User Interface

Citrix XenServer

Citrix XenCenter

Multi-Node Management Server

The CloudStack Management Server is deployed on one or

more front-end servers connected to a single MySQL database.

Multi-Site Deployment

The CloudStack platform scales well into multiple sites

through the use of zones.

Managing Networks and Traffic

In a CloudStack, guest

VMs can communicate

with each other using

shared infrastructure

with the security and

user perception that

the guests have a

private LAN.
