Types of Cloud Computing
Types of Cloud Computing
Cloud computing has five key characteristics: a) Broad network access, b) On-demand self-service, c) Resource pooling or shared services d) Rapid elasticity and e) Measured Service. Each of these characteristics needs to be present to qualify a cloud service. New concepts to the analysis and use of cloud computing are developed. One such concept uses cloud relationships: aggregation, composition and federation. Another concept is that of cloud cells, somewhat akin to cloud gears but with greater functionality from an object oriented perspective. Cloud cells provide specialization as they have only one function, such as data storage, providing a database service or web services, for example. Applying these two novel concepts means that you can re-use cloud cells and, through various combinations, create a variety of cloud services. This approach is extended further by creating cloud patterns. These describe distinct use cases based upon a combination of cloud cells and their relationships.
