The document describes Eucalyptus, an open-source software for building private and hybrid clouds. It discusses Eucalyptus architecture including the Cloud Controller (CLC), Cluster Controller (CC), Node Controller (NC), and Walrus storage controller. It provides details on Infrastructure as a Service (IaaS) and compares features between the open source and enterprise editions of Eucalyptus. Commonly used Eucalyptus commands are also listed.

4. IAAS
• Infrastructure as a Service is a provision model
in which an organization outsources the
equipment used to support operations, including
storage, hardware, servers and networking
components.

5. Characteristics and components of IAAS
• Automation of administrative tasks
• Virtualization
• Dynamic scaling
• Desktop virtualization
• Policy-based services
• Internet connectivity

8. Eucalyptus Introduction
• A software platform for the implementation of
private cloud computing on computer clusters.
• There is an open-core enterprise edition and an
open-source edition.
• Began as a research project in the field of high
performance computing (HPC) under the
direction of Professor Rich Wolski in the
Computer Science Department at the University
of California, Santa Barbara.

9. Eucalyptus Architecture
• Distributed System
– Components implemented as webservice
• Components run on top of existing resources
– Linux distribution agnostic
• Ubuntu, RHEL, CentOS, Debian, opens USE
– Hypervisor agnostic
• Xen, KVM, VMware

10. Eucalyptus Architecture

11. Eucalyptus Architecture
• CLC(Cloud Controller)
– User interface to interact with the cloud
• Standard SOAP API matching the Amazon EC2 API
• Query Interface
– Euca2ools and ElasticFox
– Talks with the Cluster Controllers(CC)
• Holds all information linking users to running instances
• Collection of available machines to be run
• View of the load of the entire system

12. Eucalyptus Architecture
• WS3(Walrus Storage Controller)
– Storing the machine images (MI) that can be
instantiated on the cloud
– Accessing and storing data (either from a running
instance or from anywhere on the web)
Note: Currently the machine on which the Cloud
Controller runs also hosts the Walrus Storage Controller
(WS3), this limitation will be removed in a forthcoming
version

13. Eucalyptus Architecture
• CC(Cluster Controller)
– Receive requests to allocate MI (machine images)
from the Cloud Controller
– Decides which Node Controller will run the Minst
(machine instance)
– Manage any virtual networks that the MInst run in
and routing traffic to and from them
– Runs the EBS Controller
• EBS(Elastic Block Storage Controller)
– Provides block-level network storage that can be
dynamically attached by VMs

14. Eucalyptus Architecture
• NC(Node Controller)
– Runs on the physical machines on which the
MI(machine image) will be instantiated
– When request to start a it will:
• 1. Verify the authenticity of the user request
• 2. Download the image from WS3
• 3. Create the requested virtual network interface
• 4. Start the instance of the machine image running as a
virtual machine (VM)
– Stopping a virtual machine corresponds to performing
the opposite operations

15. Deploy of Eucalyptus
Three typical types of deployment

16. Deploy of Eucalyptus
Different eucalyptus packages should be install into
different controllers(CLC, CC, NC). Below is a typical
structure of a NC.

17. Our Eucalyptus Cloud
We have two machines to deploy the Cloud. One is an IBM
Server with 16G memory, we use it as a Node Controller.
The other is a ordinary PC with 3G memory .

18. Our Eucalyptus Cloud
The Command

running
instances
EMI
EKI
ERI
Instance
Id
Internal External VM Type
IP IP

19. • EMI(Eucalyptus Machine Image), EKI(Eucalyptus
Kernel Image), ERI(Eucalyptus Ramdisk Image)
– To run an instance of a VM image, the image must be
associated with a qualified kernel and ramdisk image.
• Internal IP
– Private IP used to communicate between instances in the
same security group
• External IP
– Public IP connects to the instance and is subjected to the
security group rules
• VM Types
– The type of the running instances

20. Our Eucalyptus Cloud
We can manage and control
the cloud by provided web
interface.
URL:
http://10.214.10.196:8843.
From the web interface we
can configure many
attributes for the cloud.
e.g. There are five VM types
provided by eucalyptus. We
can manually configure the
size for them.
