This document provides an introduction and overview of OpenStack, an open-source cloud computing platform. It defines cloud computing and describes the main components of OpenStack, including Nova for compute resources, Keystone for identity management, Horizon for the dashboard interface, Cinder for block storage, Swift for object storage, Glance for images, and Neutron for networking. It lists many large companies that use OpenStack and provides examples of how OpenStack can be used for applications such as web hosting, big data, and content delivery. The document concludes with instructions for accessing local and online demonstrations of OpenStack.

4. Cloud computing
•Definition (NIST):
–Cloud computing is a model for enabling ubiquitous, convenient, on-
demand network access to a shared pool of configurable computing
resources
•Types
–Private/public/hybrid
•Service models
–IaaS
–PaaS
–SaaS
Example of cloud.

5. What is OpenStack?
“OpenStack is a cloud operating system that controls large
pools of compute, storage, and networking resources”.
– OpenStack website.

6. Who is using OpenStack?
• Paypal, eBay, AT&T, Telefonica, Dell, HP, IBM, RedHat, Canonical,
Rackspace, VMWare, …

7. Compute (Nova)
• Manage machines at scale
• Supports (ordered by maturity)
– QEMU/KVM
– Hyper-V
– VMWare
– Xen
– Bare metal
– Docker containers
– LXC
• Alternatives out there: Amazon EC2, Docker

8. Identity Management (Keystone)
• Defines projects, users, groups, roles and their permissions
• Authentication
– Name and password
– LDAP
– Other external methods (ie: Kerberos)
• Authorization
• Token generation
• Domains (higher level tan projects), Federation

9. Dashboard (Horizon)
• Self-service web portal
• Provides catalogue of services

10. Storage
• Block storage (Cinder)
– Persisten block-level storage device, aka virtual hard drive
• Shared file system (Manila)
– Shared block storage
– NFS, HDFS
• Object storage (Swift)
– Store and retrieve through HTTP via RESTful API
• Image service (Glance)
– Manage VM disk images

11. Networking (Neutron)
• User defined networks
• DHCP
• NAT
• SDN

12. More services
• Ceilometer – Telemetry
– Statistics and monitors for billing, benchmarking, …
• Heat – Orchestration
– Composite cloud applications
– Kind of like docker-compose
• Sahara – Elastic Map Reduce
– Hadoop cluster provisioning
• Magnum – Containers
– Expose Docker and Kubernetes

13. Example applications
• High throughput computing
• Web hosting
• Public cloud
• Web service
• eCommerce
• Big Data
• DBaaS
• Video Processing and Content Delivery
• From the sample configurations in the OpenStack website:
