Eucalyptus is open source software that implements cloud computing within a datacenter. It provides an Infrastructure as a Service (IaaS) solution for enterprises and service providers to build their own on-premise private clouds. Eucalyptus architecture consists of 5 components - the Cloud Controller (CLC) for high-level scheduling, Cluster Controllers (CC) to manage virtual machines, Node Controllers (NC) that execute VMs on host machines, Storage Controller (SC) for block storage, and Walrus for persistent object storage. Together these components allow users to deploy and manage virtual computing environments in a cloud-like manner.

4. Virtualizzazion and Cloud infrastructure
 Pay only for the resources being used
from moment to moment.
 Users can acquire and release resources
dynamically in response to customer
demand or offered load;

5. Who is already with the
head to the clouds?

6. Cloud vs Grid
 Small number of users
(they must know what
they doing…);
 Priority queues for
resource access;
 Other users must wait!
 Complex policy
mediation;
 Large number of users
(illusion of “infinite scale”
it is not necessary that they
know how it works);
 Single user cannot cause a
resource shortage;
 resource allocations are
“on-demand”
 Multiple clouds
simultaneously;
The CLOUD The GRID

7. Some words about Amazon.com

8. http://aws.amazon.com
 AWS is a platform to access a suite of elastic IT
infrastructure services as your business demand;
 Acquire and release resources dynamically;
 Deployment a computing environment make the
most sense for the problems you’re trying to solve:
 Compute power;
 Storage;
 services “on-demand”.
 You pay only for what you use.

9. AWS: Principal Components
 http://aws.amazon.com/EC2
 Virtual computing environment;
 Interfaces to launch instances of OS;
 Load OS with your custom application environment;
 http://aws.amazon.com/S3
 Your data “any time, any where” ;
 Write, read, and delete objects;
 The number of objects you can store is unlimited (what?!).
 http://aws.amazon.com/EBS
 Storage that persists independently from the life of an instance.
 can be mounted as devices by Amazon EC2 instances.
 Multiple volumes can be mounted to the same instance.

10. AWS is a infrastructure IT web service based that allow you to deploy the must
compute enviroment “on-demand” that can solve your problem to pay just the time
neccessary to solve the problem.

18. Eucalyptus: Architecture

19. Eucalyptus: Features
 Eucalyptus is compatible with many Linux distributions:
Ubuntu , RHEL , OpenSuse, Debian, Fedora, and
CentOS.
 Easy to install and highly modular;
 Standard communication protocols;
 The framework implements virtualized machine and
storage resources that are interconnected by an isolated
layer-2 network;
 The API are compatible with Amazon!
 The machines are available to a user community that
accesses them via logins.
 Software supported: XEN, KVM

20. Eucalyptus: The 5 Componets
 A full Eucalyptus platform is build from 5 high-level
components, each with its own Web-service interface;
 3of5 components (CLC/CC/NCs) are involved for
manage, schedule and execute the VMs instance.
 2of5 components (SC/Walrus) are involved for manage
and storage the user’s data.

21. Eucalyptus: The 5 Componets / 3of5
 CLC, (Cloud Ctler) high level scheduling decisions;
 CC, (Cluster Ctler) gather information about a set of
VMs and schedules VM execution on specific NCs;
 NC (Node Ctler) control the:
 Execution, inspection, termination of VM instances on
the host where it runs;
 queries and controls the OS and Hypervisor;
 response to queries and control requests from the cluster
controller.

22. Eucalyptus: CLC

23. Eucalyptus: The 5 Componets / 2of5
 SC (Storage Ctrler):
 block-accessed network storage ;
 interfacing with various storage systems (NFS, iSCSI, etc.);
 sends disk traffic across the locally attached network to a remote
storage location (e.g. Amazon EBS ).
 Walrus (put/get storage) allows users to:
 Store persistent data;
 Organized as eventually-consistent buckets and objects;
 Create, delete, list buckets, put, get, delete objects, and set access
control policies;
 Compatible with Amazon’s S3, and supports the Amazon Machine
Image (AMI ).
