2.1 vCloud Operations Framework
An IT organization’s adoption of IT as a Service (ITaaS) in a vCloud is evolutionary—the people, processes, and tools continue to evolve over time. The organizational structure and critical processes that support the adoption of ITaaS via vCloud computing are defined by the underlying VMware vCloud Operations Framework (VOF) as shown in the following figure.
Figure 2. vCloud Operations Framework
The vCloud Operations Framework consists of the following layers:
v
Cloud Business and Consumer Control – Addresses business-driven strategy
in the context of consumer-
driven requirements and demand for vCloud services, the management of IT from a business perspective, and consumer interaction management.
vCloud Service Control – Converts the consumer-
driven requirements and demand, supported by business drivers, into vCloud service definitions
. It also manages service development, creates Service Level Agreements, reports SLA compliance results back to the business and its consumers, and manages the lifecycle of services included in the service portfolio.
v
Cloud Operations Control – Defines, deploys, and executes vCloud operations-related processes
and supporting tools, and proactively manages the operations and delivery of vCloud services,
with an emphasis on policy-driven automation.v
Cloud Infrastructure Control – Architects and deploys the underlying vCloud infrastructure on which the services are offered, provisioned, and run.
As the following figure shows, all of these layers are required for support of IaaS, PaaS and SaaS services.
