The question I am trying to answer at the moment is “what makes an ICT service Cloud ready?”

The reason for the question is that the answer is needed to further clarify what a Cloud service is actually is, in order to avoid buying a Cloud washed service. After some research, I have collated two lists. The first is a set of “Cloud Characteristics”; things that make Cloud really cloud. The second list is a set of “High Level Principles”; things that surround the Cloud characteristics in more detail to give better context.

As always, the caveat, this is my own thinking supported by a good measure of research and conversation.

Cloud Characteristics

Characteristic Notes
On-demand self-service Consumer can manage their own services, via a portal, without needing intervention from the supplier.
Broad network access Services are available over the internet and on standard devices such as smartphones, tablets, laptops, and workstations.
Resource pooling The service is built on shared architecture (multi-tenanted) over which the consumer has no control.
Rapid elasticity Services can be speedily taken up and decommissioned.

Cloud Principles

Characteristic Notes
Commoditised Services could be delivered by multiple suppliers and are considered commoditised.
Configurable not Customisable Services are configurable but not customisable as opposed to customization, which requires a change to the service itself.
Augmentable Services are able to be augmented, meaning that the service   provides capabilities allowing additional capabilities to be introduced   without changing the service itself.
Technology Independent Services are independent of the technology stack.
Device Independent Services are able to be consumed on commoditised devices. I.e. Smartphones, tablets, laptops, workstations.
Transportable Services are able to be moved between cloud types (public, private, community) and ideally, between Cloud providers.
Compliant Services comply with standards as required by the consumer.
Discoverable Services can be discovered by the wider community, as appropriate.
Well-Defined and Understandable Services are understood and defined at a business function layer as opposed to a technical solution.
Secure Delivery Services are delivered in a manner that complies with the security requirements of the consumer.
Secure Content Information managed by the service complies with any information security requirements that the consumer has.
Reliable The service reliable according to a standardised SLA.
