2. Goal
   • Highly extensible
   • Open up the definition of workload/trait/scope
   • Component is fully customizable for operators
   • Kubernetes native
   • Allow user to bring in their existing controllers
   • Seamlessly integrate operator framework

3. Worload Definition
   • Workload contains a schema
   reference
   • This allows us to take schema out of a
   component.
   • It can refer to any schema that
   contains self identification.
   • A component is an instantiation of a
   workload with “customizable” fields

4. Component
   • Component instantiate a workload
   • A developer creates the component.
   • It follows the schema defined in the
   workload.
   • A component is close to a CR if the
   workload Definition contains a CRD
   • A parameter now can point to any fields
   in the schema

5. Trait/Scope
   • Trait/Scope both reference schema
   • Trait and scope are as extensible as
   workloads
   • Application operators instantiate
   Trait/Scope in the application
   configuration

6. Application Configuration
   • Instantiation of traits are
   embedded in the component.
   • Components refer to
   instantiated scopes.

7. Future plan
   • Dependency
   • We need a way to describe dependencies between components.
   • Policy
   • We need a way for a trait to apply to extended workloads
   • We need a way for an application developer.
   • Trait registry
   • Trait interacts with workloads
   • Standard traits
