The NIST definition lists five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service. It also lists three "service models" (software, platform and infrastructure), and four "deployment models" (private, community, public and hybrid) that together categorize ways to deliver cloud services. The definition is intended to serve as a means for broad comparisons of cloud services and deployment strategies, and to provide a baseline for discussion from what is cloud computing to how to best use cloud computing.
To help customers understand cloud and cloud computing better and to show that cloud computing is not a single solution however constist out of many solutions which can be combined to form other solutions Oracle has released a short video to create a mindset which uses the analogy with the Periodic Table of Elements which is called the Oracle Cloud Periodic Table.
This video shows the vision of Oracle on cloud computing, or at least a part of the vision and creates a mindset to understand that your specific cloud solution will most likely be the combination of a number of modules which are offered from within a cloud platform. Not only Oracle is making use of this model, it is a growing trend in hybrid clouds and is largely based upon open standards and the as-a-Service way of thinking.
