This presentation discusses content from the document, “ODCA Master Usage Model: Service Orchestration.” The session illustrates the usage model for service discovery and orchestration for cloud services. This usage model includes the components, repositories, data structures, conversation maps, and workflows that assist a cloud consumer in defining required services, and the associated cloud provider to orchestrate services to meet objectives determined by the cloud subscriber and for the appropriate context of use. It defines automation required for orchestration that includes programmatic interfaces, interaction patterns, control interfaces, and lifecycle management.

Important processes, requirements and considerations in
orchestration of cloud services
3. UM BACKGROUND
Cloud Service Orchestration v2.0
The Service Orchestration v2.0 UM addresses and identifies:
1. Important Usage Scenarios to accommodate in an Orchestrator
2. The Architecture and elements of the Orchestrator
3. API and Interface planning
4. KPI definitions for Service Orchestration

4. UM CORE – KEY ELEMENTS
five high-level groupings of usage scenarios based on the orchestration tasks that cloud subscribers
execute, which also map closely to the industry concepts of Install, Move, Add, Change, and Delete
The orchestration process itself must belong to the cloud consumer, who has overall responsibility for
triggering requests and paying for services. However, the orchestration systems and tooling can be
provided by the consumer, or one of the cloud provider parties. The orchestration process from the
cloud provider side can also initiate a process or processes in the cloud consumer side: for example,
notification or alerting.
With REST, there is the concept of resources and collections. A resource is a typed object with
properties, methods, and associations with other objects. A collection is a directory or group of
resources. Since resources are addressed through Uniform Resource Identifiers (URIs), the expectation
is for the cloud provider to use conventional URI design to publish APIs
KPIs are control tools designed to allow the measurement of the following aspects of a service:
1. Progress
2. Compliance
3. Effectiveness

8. Define open standards for advertisement of cloud services to cloud brokers
Define the key integration points between cloud service providers and service
consumers, and the minimum expected functionality from each side, to
enable open standards based automation between them
Define standards for encapsulating catalog entries for advertisement, all the
way from IaaS through PaaS, to SaaS levels.

9. Make sure you understand Orchestration, when
establishing Cloud services and selecting partners
Get the responsibilities and ownership for key functions
clearly defined up front
Make sure your environment can scale over time – towards
including alternate clouds and partners
Define key measures up front for orchestrating services,
and monitor their achievement over time
