Cloud Solution Framework

Any cloud solution is based on the following high-level framework:

Multitenant virtualized infrastructure: The basis for the solution is the resources combined in a
multitenant virtualized infrastructure, which combines all the elements of the data center solution,
with some extensions outside of the data center that are appropriate for the given cloud solution.

Operational management: The vital part of the framework is the operational management, which
enables the owner of the cloud infrastructure to internally maintain and operate it.

Resource management: The resource management is the middleware between the infrastructure
and the customer front-end systems. It provides the elements with which the infrastructure
components and resources are managed, as well as the necessary API for the front end and the
integration with customer-side management systems.

Business services: The business services define the way in which the cloud services are sold and
managed from a customer-facing side.

Front office portals, orchestration and automation: These are the customer-facing front-end
systems through which the customer, by the means of self-service and self-provisioning, uses the
cloud solution, chooses among the available services from the catalog, selects the service level
management, and so on.

Cloud services: The cloud services are the services that the customer— IT administrator, software
developer, or end user—is using.
