Gartner’s Hype Cycle on Clouds 6Wednesday, May 25, 2011

Clouds According to NIST “Cloud computing is a model for enabling 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. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.” National Institute of Standards and Technology http://csrc.nist.gov/groups/SNS/cloud-computing/ 7Wednesday, May 25, 2011

NIST: Five Characteristics Things that are considered cloud: ‣ On-demand, self-service ‣ Broad network access ‣ Resource pooling ‣ Rapid elasticity ‣ Measured service 8Wednesday, May 25, 2011

NIST: Three Service Models Cloud applications are: ‣ Software as a Service ‣ Platform as a Service ‣ Infrastructure as a Service 9Wednesday, May 25, 2011

NIST: Four Deployment Models ‣ Private cloud ‣ Community cloud ‣ Public cloud ‣ Hybrid cloud 10Wednesday, May 25, 2011

Infrastructure as a Service 11Wednesday, May 25, 2011

Application Layers Standard layers in a typical application: Application System Software Storage Operating System Hardware Network 12Wednesday, May 25, 2011

Infrastructure as a Service Parts of the infrastructure offered as service to your app: Application System Software Storage Operating System Hardware Network 13Wednesday, May 25, 2011

Infrastructure as a Service ‣ Advantages: • Easily scalable • Move from capital expense to operational expense • Metered use • Don’t worry about hardware 14Wednesday, May 25, 2011

Example: The Rackspace Cloud ‣ The RackspaceCloud is what used to be called Mosso ‣ Powerful API for managing your cloud ‣ Easy access in PHP through Aleksey Korzun’s PHP API: • http://github.com/AlekseyKorzun/php-cloudservers ‣ Concepts • Images (various operating systems) • Flavors (configuration: mem, cpu, disk) 15Wednesday, May 25, 2011
