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 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

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 networks, servers, storage, applications, and

services) that can be rapidly provisioned and

released with minimal management effort or service

provider interaction.

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 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).
