Are Cloud Taxonomies Simple or Complex?
Much has been written about the different types of cloud taxonomies. In some ways it reminds me of the SOA confusion from 5-8 years ago where everyone was trying to label something as being “SOA” and “not SOA”. As an architect I favor simplicity – this includes cloud taxonomies. Thus, I view cloud taxonomies as follows:
Cloud taxonomies consist of a Service model and a Hosting Model.
- Service model - There are three service models: SAAS, IAAS and PAAS.
- Everything else is a scenario that falls into one of these three models (e.g. *AAS)
- Hosting model - There are two hosting models: Public and Private.
- Virtualization is an implementation choice within one of these models.
