Oss and Cloud Computing

  1. 1. BY: NISHANT KEWALRAMANI A Property of BananaIP
  2. 2. AGENDA  Concept and models  Cloud Computing & OSS- Face off  OSS Licenses catering to Cloud Computing  Illustrations © 2010 BananaIP.
  3. 3. Cloud Computing  Internet based access to computer resources  On demand availability  Resources may include- software, hardware, information  Usually Charged per unit time of usage  The name inspired by the cloud symbol used to represent internet in diagrams and flow charts.
  4. 4. Cloud Computing- Business Models  PaaS (Platform as a Service)  Computing platform provided by the service provider where customers can create applications on the platform.  IaaS (Infrastructure as a Service)  Access to IT infrastructure such as storage, processing etc. Usually shared with other customers.  SaaS (Software as a Service)  Access to Software application. Remotely and usually on demand.
  5. 5. Face Off  OSS  Software accompanied with Source Code  To promote modification and redistribution of the software  Comes with a License listing down conditions  Triggers upon distribution  Cloud Computing  Hosted by a Service Provider  To maximize usage of resources in minimal costs  Usually accompanied by pay per unit time of usage conditions  No distribution at all OSS License triggers on distribution where as Cloud Computing works on a non distribution model.
  6. 6. Affero GPL v.3  FSF’s answer to cloud computing  AGPL v.3  Preamble- “The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public…The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server.”
  7. 7. AGPL v.3 contd…  Clause 13- “if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge…”
  8. 8.  Sonatype’s Nexus-  Repository management software  Dual Licensing model- Basic version under GPL while Professional version under proprietary license  People downloaded basic version, made modifications and hosted on the cloud system without providing source code.  Sonatype moved Nexus to AGPL.
