Agenda
■ Introduction to Cloud ComputingDeployment and service modelsIn which scenario OpenStack can be used?
■ OpenStack and the open source communityA brief historyThe OpenStack Ecosystem
■ OpenStack ArchitectureOverview of the main OpenStack Projects
Keystone, Nova, Neutron, Glance, Cinder and Swift
■ Live Demo
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
Essential Characteristics of Cloud Computing
■ On-demand self-servicea consumer can unilaterally provision computing capabilities
■ Broad network accesscapabilities are available over the network and accessed through standard
mechanisms
■ Resource poolingthe 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 servicecloud systems automatically control and optimize resource use by leveraging a
metering capability
Service Models
Deployment Models
■ Public cloudThe cloud infrastructure is provisioned for open use by the general public
■ Private cloudThe cloud infrastructure is provisioned for exclusive use by a single
organization
■ Community cloudThe 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)
Public Clouds
In which scenario OpenStack can be used?
Hosted Private Clouds

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

The Four Opens
■ Open SourceApache License 2.0
■ Open DesignEvery six months the development community holds a design summit to gather
requirements and write specifications for the upcoming releaseOpen to the public, include users, developers, and upstream projects
■ Open DevelopmentPublicly available source code repository through the entire development
processPublic code reviews and roadmaps
■ Open CommunityAll processes are documented, open and transparentAll project meetings are held in public IRC channels and recorded

All Releases Liberty Release
OpenStack Releases
OpenStack is developed and released around 6-month cycles

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

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)…

OpenStack BootcampIn 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.
OpenStack Fundamentals (OS50)
OpenStack ConsultingCREATE-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
