3. What Is Cloud Computing? • Characteristics – On demand, self service – Access via standard network protocols / APIs – Resource pooling (multi-tenant) – Rapid scale-out – Metered service http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf
4. What Is Cloud Computing? • Characteristics • Deployment models – Public – Private – Hybrid http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf
5. What Is Cloud Computing? • Characteristics • Deployment models • Service models – IaaS – PaaS – SaaS http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf

10. OpenStack Mission “To 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”
11. OpenStack in numbers • 5 years old – October 2010 (Rackspace & NASA) • 12 releases – 6-month development & release cycle (Apr / Oct) – Labelled alphabetically: Liberty, Oct 2015 • 20M+ lines of Python code • 34,000+ people • 500+ companies • Walmart: 100,000 compute cores in production
12. OpenStack Conceptual Model • OpenStack controls large pools of compute, networking, and storage resources throughout a datacenter, managed via a dashboard that gives administrators control while allowing their users to provision resources through a web interface
13. OpenStack Compute Resources • VMs – Nova – KVM; Xen; ESXi; Hyper-V • Bare metal – Ironic • Containers – Magnum
14. OpenStack Core Components • Compute – Nova – Glance • Networking – Neutron • Storage – Cinder – Swift • Dashboard – Horizon • Identity – Keystone
15. How open is OpenStack? • Open source – Apache License 2.0 • Open design • Open development: git.openstack.org • Open community: wiki.openstack.org
16. Try OpenStack • DevStack – http://docs.openstack.org/developer/devstack/ – Self-hosted: VM (single / multi) or bare metal • TryStack – http://trystack.org/ – No cost… you have to join their Facebook group • Ravello Systems – https://www.ravellosystems.com/solutions/openstack/cloud-o penstack-lab – Pay per use, after 14 day trial period
