  1. 1. Piattaforme open source per il cloud computing Carlo Daffara European Working Group on Libre Software CloudWeaversOpenSourceDay 2012
  2. 2. “cloud computing is a model for enablingubiquitous, convenient, on-demand networkaccess to a shared pool of configurablecomputing resources (e.g., networks, servers,storage, applications and services) that canbe rapidly provisioned and releasedwith minimal management effor t orser vice provider interac tion .” – NISTOpenSourceDay 2012
  3. 3. NIST Service/Deployment models● Service Models: ● IaaS (e.g EC2, rackspace) ● PaaS (e.g GAE, Azure) ● SaaS (e.g Gapps)● Deployment model: ● Private cloud ● Public cloud ● Hybrid cloud (Private than can use Public)OpenSourceDay 2012
  4. 4. NIST Service/Deployment models● Elasticity ● Expands and Shrinks as needed ● E.g Elastic Load Balancing, Elastic Map Reduce● Measured Service ● Utility Pricing. You pay for what you use ● E.g $0.08 for one hour of small instance● On-demand ● You get it when you ask for it ● E.g One api call and you get your machine, no queueOpenSourceDay 2012
