IDC has posted an overview of what the term “cloud service” means, including an eight-point checklist. Here's my own shorter version on this. A 'cloud service':
- Is accessible over the public Internet.
- Is accessed using standard web services protocols like XML or JSON over HTTP — proprietary client-side hardware and software are not acceptable.
- Is billed elastically, so consumers can pay for what they use.
- Scales elastically, so consumers don’t not need to worry about capacity as long as they stick within their SLAs.
Is a Cloud service any different than an API or a web service?
