Cloud service management is concerned with aligning both worlds, that is, the world of cloud computing and service management and introducing good cloud management practices among customer, consumer and supplier organisations.
Cloud computing and cloud-based services are not a new technology. Cloud principles were followed even for Mainframes circa 1950s and 1960s.
There are many frameworks and methods for the management of IT and for service management. In most cases, cloud computing is described as a business model for use of other underlying technologies and not as a technology. Those underlying technologies, such as virtualization, provide the basis for employing cloud computing concepts. Cloud in itself if not technology.
The purpose and scope of cloud service management are described below:
Establish appropriate methods for the management and operation of cloud-based services.
Embed cloud service management practices into existing IT development and support structures.
Oversight of the design, development and transition of cloud-based services.
Management and operation of cloud-based services.
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing recourses, that is, networks, servers, storage, applications and services that can be rapidly provisioned and released with minimal management effort or service provider interaction.
This cloud model is composed of five essential characteristics, three service models and four deployment models
