Eucalyptus is an open source software that implements private and hybrid clouds within an organization's existing IT infrastructure. It includes several components - the Cloud Controller (CLC) that handles user requests and metadata, Walrus for storage, Cluster Controller (CC) for scheduling VM instances, Storage Controller (SC) for block storage, and Node Controller (NC) that executes VM instances. Eucalyptus enables organizations to create private clouds without requiring specialized hardware or retooling their existing IT systems. While flexible and scalable, early versions of Eucalyptus experienced issues with insufficient resources and stability when starting and connecting VM instances.

2. Introduction
• Eucalyptus is an open source Linux-based
software architecture that implements
scalable, efficiency-enhancing private and
hybrid clouds within an organization's IT
infrastructure.
• Eucalyptus was designed from the ground up
to be easy to install and as non-intrusive as
possible.

3. Cloud Controller (CLC)
• Each Eucalyptus installation includes a single
Cloud Controller (CLC) that is the user-visible
entry point of Eucalyptus installation.
• The CLC is responsible for processing incoming
user-initiated or administrative requests

4. Cloud Controller (CLC)
• The CLC is composed of a
collection of services that
handle user requests and
authentication, user
metadata (VM images
and ssh key pairs) and the
management and
monitoring of VM
instances.

5. Walrus
• Walrus implements scalable storage. The
current implementation of Walrus is providing
a mechanism for persistent storage and access
control of virtual machine images and user
data.
• Walrus and CLC are high level components,
which are included in all installations: So every
cloud has only one Walrus and one CLC

6. Cluster Controller (CC)
• The CC is responsible for gathering state
information from NCs.
• Scheduling incoming VM instance execution
requests to individual NCs.
• CC is also manage the configuration of public
and private instance networks.

7. Storage Controller (SC)
• The SC provides network storage that can be
dynamically attached by VMs.
• SC controls VMs snapshots.
• The SC supports the Amazon Elastic Block
Storage (EBS)

8. Node Controller (NC)
• The Node Controller (NC) is the component
that executes VM instances
• NC is responsible for instance start up,
shutdown, cleanup...

9. Eucalyptus Enterprice Edition
• Eucalyptus EE is commercial version of
Eucalyptus.
• Eucalyptus EE has many features that doesn’t
have in open source edition:
– VMware Hypervisor Support (ESXi)
– SAN
– HA
– AD integration

11. Suitable and scalable
• Eucalyptus was designed from the ground up
to be scalable and to achieve optimal
performance in diverse environments
• Eucalyptus is flexible and can be installed on a
very minimal setup. Yet it can be installed on
thousands of cores and terabytes of storage.
• Ubuntu, Red Hat, CentOS, openSUSE and
Debian

12. What can you do with it?
• Eucalyptus enables the creation of private
clouds, with no requirements for retooling the
organization's existing IT infrastructure or
need to introduce specialized hardware.
• Eucalyptus implements an IaaS (Infrastructure
as a Service) private cloud

13. At The End
• Eucalyptus can be controlled by browser and
command line tools
• HP, Sony, NASA and United States Secretary of
Defense

14. Problems
• Resources was insufficient for running
instances
• Hypervisor (Xen) -> kernel change
• Starting VM instance and connecting VM
instance -> Eucalyptus fall apart in my hands

15. • Eucalyptus web interface
• Commands inside Node Controller (NC)
