2. Why Reference Architecture
• Articulate the domain and concepts
• Provide a common vision, understanding, taxonomy
among organizations
• Effectively reduce complexity and speed up the
development of new products, product lines and
portfolio
• Provide a guideline for inter-operability and standards
• Model the functions and services of implementation
systems
• Capture and share patterns and best practices

5. Cloud Computing
from NIST SP800-145, September 2011
• Cloud computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared
pool of configurable computing resources (e.g.,
networks, servers, storage, applications, and
services) that can be rapidly provisioned and
released with minimal management effort or service
provider interaction.

6. Cloud Computing Model
(from NIST SP800-145, September 2011)
Essential Characteristics: Service Models:
• On-demand self-service. • Software as Service (SaaS).
• Broad network access. • Platform as a Service (PaaS).
• Resource pooling. • Infrastructure as a Service (IaaS)
• Rapid elasticity. Deployment Models:
• Measured service. • Private cloud.
• Community cloud
• Public cloud.
• Hybrid cloud.

19. Business-Process as a Service (BPaaS)
• Business process services are any business process
(horizontal or vertical) delivered through the Cloud
service model (Multi-tenant, self-service
provisioning, elastic scaling and usage metering or
pricing) via the Internet with access via Web-centric
interfaces and exploiting Web-oriented cloud
architecture. The BPaaS provider is responsible for
the related business function(s).
