1.6 Service Development Methodology
The best practices approach for defining and designing VMware public cloud service:
• Involves all necessary stakeholders.
• Documents business drivers and requirements that can be translated into appropriate service definitions.
• Takes a holistic view of the entire service environment and lifecycle, including:
o Setup, which includes definition and design
o Request and approval
o Provisioning
o Consumption
o Management and operations
o Transition and termination
There must be a conscious awareness of what consumers and the provider of the service experience at each stage of the service lifecycle to create the necessary service definition elements for the consumer-facing service level agreement (SLA) and internal-facing operational level agreement (OLA) criteria.
• Defines the service scenarios and use cases.
• Understands the service’s components, interactions, and sequences of interrelated actions.
• Defines the users and roles involved with or interacting with the services so that the services created are user-centric.
• Defines the SLA for the services and service components in the following areas:
o Infrastructure
o Application / VMware vSphere vApp™
o Platform
o Software
o Business
• Defines service quality for these areas:
o Performance
o Availability
o Continuity
o Scalability
o Manageability
o Security
o Compliance
o Cost and pricing
• Defines the business service catalog and supporting IT service catalog.
