2.3  Taxonomy of Cloud Computing

Several taxonomies [21,22,24] of the cloud computing blueprint can be found, but most were created from the perspective of vendors that are part of the landscape and not from the perspective of enterprise IT, the consumers of cloud services, and software. This taxonomy is split into seven major sections as shown in Fig. 2.1.

This includes architecture, virtualization management, core services, security, data governance, and management services. The subtaxonomy core services include replication, discovery, and load balancing. A scalable, robust, and intelligent replication mechanism is crucial to the smooth operation of cloud computing. Another subtaxonomy security includes encryption/decryption, privacy, federated identification, authorization, and authentication. Ultimately, the cloud computing taxonomy describes certain patterns in how to understand the cloud components and how to do things. At the same time, it needs to provide some specific grounding to address the complex issues of integration of services within cloud computing that focus on providing computable semantic interoperability.

2.3.1  Cloud Architecture

Cloud architecture is the design of software applications that use Internet accessible and on-demand service. Cloud architectures are underlying an infrastructure that is
