description
This presentation summarizes the architecture section of our more detailed report on Service Portfolio Planning and Service Architecture for Cloud ServicesCloud Computing is concerned with deployment, but introduction of Cloud Services cannot be a purely technical deployment matter. There are numerous considerations that may impact on all the Stakeholder Views. In the full report report, we show how the CBDI-SAE approach can be used and extended to architect for Cloud Services. We extend our current guidance with new and refined classification systems, diagrams, policy types and techniques designed to promote visibility and good governance over Service Portfolio Planning activities and Cloud Services provisioning.

Does it Matter Where the Service is Located?

What are Cloud Services? Simply put, they are Services provided where:•Their physical location is transparent to the Service consumer. •The computing infrastructure is provided on a shared basis to derive economies of scale, or to improve agility, scalability or reliability.

Service Architecture Views Modeling Considerations
View Modeling Consideration
Business For traceability, the associations between Cloud Services and objects in the Business Model should be shown, where relevant. For example in the case of Cloud Services classified as Core Business and Process Services that should have associations with Business Process, Business Type, or Business Service in the business model.
A Cloud Service may introduce an industry standard business process; or a business process and semantics that are shared across a supply chain or information ecosystem.
Specification The Cloud Service needs to be classified and placed accordingly in the Specification Architecture.
The contracts between the provider and consumer may need to be expanded to capture additional detail regarding the provision and consumption of Cloud Services, such as security classifications, charging mechanisms, and to record associations between different contract types (Service Specification, , Commercial Terms, etc). At the same time, the level of detail in some areas of the contracts such as implementation instructions may decrease.
Implementation If the Cloud Service is an implementation-only consideration, that is it is used to implement a Service in the Specification Architecture, but not visible in the Specification architecture itself, then it is only modeled as is part of the internal architecture of the Service. For example an Infrastructure or Utility Service that is used exclusively to implement a Core Business Service
Deployment In a private cloud, the nodes hosting the service endpoints and the deployment artifacts would be modeled in the normal way, though little may be known about the deployment architecture of an external, public cloud service.
However, the external behaviors are of interest – such as configuration management, operational management, (particularly where Services are provided as a mechanism to accomplish this), compliance with standards, and hence level of portability that enables a switch between providers

Mapping Cloud Services and CBDI-SAE Service Classifications
Cloud Classification CBDI-SAE Service Layers
Software as a Service (SaaS) Fairly vague term, given all cloud services are software. So useful to decompose this a little more.
Application Capability Service
Application Process Service
Core Business Service
Business ‘Process’ Process Service
Business ‘Service’ Core Business Service
Business ‘Function’ Utility Service
Infrastructure as a Service (IaaS) Infrastructure Service
Platform as a Service (PaaS) Infrastructure Service
