  1. 1. Cloud Computing ReferenceArchitecture from NIST & IBM General Discussion Richard Kuo, Professional-Technical Architect, Cloud Realization, New Technology Product Development Engineering
  2. 2. Why Reference Architecture Articulate the domain and concepts Provide a common vision, understanding, taxonomyamong organizations Effectively reduce complexity and speed up thedevelopment of new products, product lines andportfolio Provide a guideline for inter-operability and standards Model the functions and services of implementationsystems Capture and share patterns and best practices4/17/2012 Creative Common BY-NC-SA2

  5. 5. Cloud Computingfrom NIST SP800-145, September 2011 Cloud computing is a model for enabling ubiquitous,convenient, on-demand network access to a sharedpool of configurable computing resources (e.g.,networks, servers, storage, applications, andservices) that can be rapidly provisioned andreleased with minimal management effort or serviceprovider interaction.4/17/2012 Creative Common BY-NC-SA 5

  19. 19. Business-Process as a Service (BPaaS) Business process services are any business process(horizontal or vertical) delivered through the Cloudservice model (Multi-tenant, self-serviceprovisioning, elastic scaling and usage metering orpricing) via the Internet with access via Web-centricinterfaces and exploiting Web-oriented cloudarchitecture. The BPaaS provider is responsible forthe related business function(s).4/17/2012 Creative Common BY-NC-SA19
