Originally from the UK, I go back frequently to visit family. During this Christmas visit the Open Group published their standard for a Cloud Ecosystem Reference Model. I was the co-chair for the project that produced this material and I know how much work went into producing this.
This standard defines the Cloud Ecosystem Reference Model.
It provides guidance on applying the Cloud Ecosystem Reference Model with the TOGAF® and ArchiMate® standards to develop, maintain, and govern an Enterprise Architecture for the Cloud Ecosystem.
The approach described in the standard enables practitioners to effectively align business and technical capabilities in creating architectural components, their inter-relationships, and to effectively manage interactions and relationships between the participants of the Cloud Ecosystem in order to minimize the impact of changes in Cloud Services (either developed by the enterprise itself or by participating entities of the Cloud Ecosystem).
The standard uses Archimate to illustrate the relevant diagrams and models required to apply the Cloud Ecosystem Reference Model. The Cloud Ecosystem Reference Model defines the major actors and their relationships and a minimum set of Architecture Building Blocks (ABBs). The model describes the architectural capabilities to be realized and facilitated by at least one of the new or existing participants of an enterprise Cloud Ecosystem. The model establishes a common language for the various participants of an enterprise Cloud Ecosystem that supports the validations of Cloud Service Providers’ solutions to achieve architectural integrity of business solutions of an enterprise.
