This week sees the releases of Cloud ISO standards, another sign that Cloud is maturing rapidly. Being able to measures Cloud services against an ISO lends credibility and demystifies some of the fluffy bits of Cloud that we have seen in the last two years. Heavily built on NIST, the standards extend vocabulary and architecture to provide a comprehensive view.
So for the geeks, architects, planners, and other builders out there the two documents can be found here.
The first document provides an overview of Cloud computing and general vocabulary.
“Cloud computing is a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand. The cloud computing paradigm is composed of key characteristics, cloud computing roles and activities, cloud capabilities types and cloud service categories, cloud deployment models and cloud computing cross cutting aspects that are briefly described in this clause 6.”
ISO notes that Cloud computing “is an evolving paradigm.”
The second document provides a reference architecture for Cloud computing, which will be of great help to Enterprise Architects everywhere.
“The CCRA focuses on the requirements of “what” cloud services provide and not on “how to” design cloud-based solutions and implementations. The CCRA does not represent the system architecture of a specific cloud computing system, although it could put constraints on a specific system. The CCRA is not tied to any specific vendor products, services or reference implementation; nor does it define prescriptive solutions that inhibit innovation.”
These standards coupled with NIST provide a mechanise to evaluate whether a service is true Cloud, or not. This will go a long way to removing Cloud washing from the market. It will also drive Cloud providers to seek ISO accreditation, which is likely to replace Cloud Codes that have been developed, such as in New Zealand and Australia, over time with a definitive stamp of approval.
