Private Clouds – What are they?

It is a Cloud which resides within your own datacenter, company or systems in which all the data is stored within your location, plus it is managed by you. In other words you are the King of the Cloud.

In the private cloud the resource capacity is limited by the physical infrastructure which you rely on.

And can I use them for?

Private clouds can be use for many use cases• Research• Data Analysis• Development and Testing• Web applications

But its mostly used by industries which are governed by security audits (PCI, SOX) or stored sensitive data which can not be hosted in a public cloud due to security reasons.

How do they work?Based on virtualization.

A controller usually coordinates the provision and keeps track of all the resources (network, storage, virtual machines).

If more capacity is needed, more physical servers or nertworks are added.

How do they work?

Eucalyptus• First cloud platform released to the public (2008)• Development cycle is every 2 years• 100% compatible with Amazon web services API• Mostly used by universities and business which

use AWS services.• Uses as simple design architecture (controller –

node)• Supports KVM, Xen and Vmware provisioning• Interaction with Vmware and enterprise storage

require paid licenses.• Written in Java and C++

OpenStack• Released by rackspace and NASA in 2010.• Faster development cycle (2 relases per year) but it

makes it really difficult to keep up with updates once you install it.

• Has some compatibility with Amazon API.• KVM is the hypervisor of choice.• In theory supports Vmware, Xen.• Complex design and architecture (multiple components

with interdependencies). • Becoming more popular in last year. • Originally used by rackspace to promote their “Alternative

to AWS”. • Written in Python

CloudStack• Released also in 2010 by Cloud.com, formerly

known as VMOps which now is part of Citrix.• Citrix released the code to the Apache fundation in

2012 and as for now CloudStack is an Apache project.

• Has it’s own API and its compatible with some of the Amazon AWS api.

• Provides built-in virtual routers, firewalls and load balancers.

• Has the best User interface of all the 3 projects.• Hypervisor agnostic.• Written in Java

DEMO

Which one is better?It really depends on your needs.

Are you going to use AWS for production? – Go Eucalyptus

You wont be using AWS? – Openstack or Cloudstack

Do you need built in features now instead of waiting for the community to build them? – Go Cloudstack

Have a large infrastructure and free hands? - Go openstack
