2. Hello!
I am Giuseppe Cossu
I am an enthusiastic OpenStack user.
I work at Create-Net as Cloud Engineer;
I am mainly involved on Cloud Computing
and Network Virtualization.

3. Agenda
■ Introduction to Cloud Computing
Deployment and service models
In which scenario OpenStack can be used?
■ OpenStack and the open source community
A brief history
The OpenStack Ecosystem
■ OpenStack Architecture
Overview of the main OpenStack Projects
Keystone, Nova, Neutron, Glance, Cinder and Swift
■ Live Demo

4. Introduction to
Cloud Computing
"Cloud Computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool of
configurable computing resources that can be rapidly
provisioned and released with minimal management effort
or service provider interaction." NIST Definition

5. Essential Characteristics of Cloud Computing
■ On-demand self-service
a consumer can unilaterally provision computing capabilities
■ Broad network access
capabilities are available over the network and accessed through standard
mechanisms
■ Resource pooling
the provider’s computing resources are pooled to serve multiple consumers
using a multi-tenant mode
■ Rapid elasticity or expansion
capabilities can be elastically provisioned and released
■ Measured service
cloud systems automatically control and optimize resource use by leveraging a
metering capability

6. Service Models

7. Deployment Models
■ Public cloud
The cloud infrastructure is provisioned for open use by the general public
■ Private cloud
The cloud infrastructure is provisioned for exclusive use by a single
organization
■ Community cloud
The cloud infrastructure is provisioned for
exclusive use by a specific community of
consumers from organizations that have
shared concerns
■ Hybrid cloud
The cloud infrastructure is a composition of two
or more distinct cloud infrastructures
(private, community, or public)

8. Public Clouds
In which scenario OpenStack can be used?
Hosted Private Clouds

clouds/

9. OpenStack and the open-
source community
In July 2010 Rackspace Hosting and NASA jointly launched
an open-source cloud-software initiative known as
OpenStack.

10. OpenStack History
■ The OpenStack mission:
“produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of
public and private clouds regardless of size, by being simple to implement and massively
scalable”
■ The OpenStack Foundation
launched in September 2012 as a non-profit corporate entity providing shared resources to
promote OpenStack software and the community around it
■ More than 500 companies have joined the project!

11. Google Trends: open source cloud platforms
http://www.google.com/trends

12. The Four Opens
■ Open Source
Apache License 2.0
■ Open Design
Every six months the development community holds a design summit to gather
requirements and write specifications for the upcoming release
Open to the public, include users, developers, and upstream projects
■ Open Development
Publicly available source code repository through the entire development
process
Public code reviews and roadmaps
■ Open Community
All processes are documented, open and transparent
All project meetings are held in public IRC channels and recorded

13. Contribution by companies
http://stackalytics.com/
All Releases Liberty Release

14. OpenStack Releases
OpenStack is developed and released around 6-month cycles
http://releases.openstack.org/

15. What is OpenStack?
“OpenStack is an open source software for building
private and public clouds which delivers a massively
scalable cloud operating system.”

16. OpenStack Software Diagram
● OpenStack controls large pools of compute, storage, and networking resources
● It is all managed through a dashboard called Horizon, that gives administrators control
while empowering their users to provision resources through a web interface.

17. OpenStack Logical Architecture

18. Core OpenStack Services

19. Additional Services
■ The Evolution of OpenStack continues with new projects:
Orchestration (Heat)
Telemetry (Ceilometer)
Database (Trove)
Elastic Map Reduce (Sahara)
Bare Metal Provisioning (Ironic)
Multiple Tenant Cloud Messaging (Zaqar)
Shared File System Service (Manila)
DNSaaS (Designate)
Security API (Barbican)
…

20. Live Demo
■ Live Demo using the
OpenStack Dashboard
graphical interface to access,
provision and automate cloud-
based resources

21. OpenStack Bootcamp
In partnership with Mirantis
CREATE-NET, the only Italian partner of Mirantis, offers two different levels of courses:
OpenStack Fundamentals is a single-day, fast-paced introduction to OpenStack basics and is intended for OpenStack end-users such as:
- project managers,
- IT professionals, business developers,
- or sales engineers
who require cloud platform operational skills and a high level understanding of cloud computing internals, using OpenStack.
OpenStack Bootcamp I
(OS100)
This three day course is for
- IT operations,
- Network Admins,
- Security or Storage architects
responsible for design, and/or indirect support and operation of an OpenStack installation.
The course provides participants with a detailed understanding of steps necessary to operate an OpenStack environment.
The lecture covers architecture, best practices, provisioning workflow, component interaction, and is the best preparation for the
real-world challenges faced by OpenStack experts.

22. OpenStack Consulting
CREATE-NET offers consulting for IaaS and PaaS Cloud solutions.
Our offer is based on the analysis and definition of OpenStack cloud-based architectures.
We analyze the needs of our customers to help them define the solution best suited to their needs.
Through our experienced team we are able to create or extend IaaS platforms based on OpenStack which
include:
• High Availability (HA);
• Multi-Hypervisor;
• Support for containers (Docker/Kubernetes);
• Object Storage and Block Storage based on Ceph;
• Advanced Networking functionalities.
We also offer:
• automation tools for infrastructure deployment
• customized solutions via PoC
• integration of vendor-specific solutions in the OpenStack
platform (via plugins , drivers , etc.)
• training and knowledge transfer
We are also active in the consultancy on the design,
development and deployment of cloud-aware
software applications
