Micro-service policy (instance)

Configured micro-service policy. In this case Clamp is creating it using Policy API.

e.g. in Beijing TCA configuration Micro-service policy contains information about metrics and tresholds

Operational policy (instance)

Policy with configured Drools Rule. In this case Clamp is creating it using Policy API.

e.g. in Beijing this policy decided whether to start APPC LCM or not.


Current control loop design and execution

Stages required to run control loop:

  1. AC blueprint design (SDC)

  2. AC blueprint distribution (SDC)

  3. CL configuration (CLAMP)

  4. CL submit (CLAMP)

  5. CL deploy (CLAMP)

Desired control loop design and execution

Stages required to run control looploop:

  1. Deployment Artifact design using SDC DCAE-D

    • In this step user should design and add to service 2 deployment artifacts:

      1. AC blueprint

    design (SDC)

  2. AC blueprint distribution (SDC)

  3. AC/CL configuration (CLAMP)

  4. CL submit (CLAMP)

  5. CL deploy (CLAMP)

Desired control loop design and execution

Stages required to run control loop:

  1. AC blueprint design (SDC)

  2. Policy model design (SDC)

    1. example policy model: policy.yaml

  3. Distribution of Policy model and AC blueprint  (SDC)

  4. AC/CL configuration (CLAMP)

    • example_saved_model_properties.json

  5. CL submit (CLAMP)

    • submit_logs.txt

      1. (DCAE_BLUEPRINT)

      2. Policy model (example: policy.yaml)

  6. Distribution of CSAR containing Policy model and AC blueprint  (SDC)

    • Both Policy and Clamp should receive Artifact distribution notification.

        pagePin10
         
      2. Gliffy

        pagePin6

  7. AC configuration (CLAMP)

    Gliffy
    nameGeneric AT Policy Configuration
    pagePin2

    • Policy should extract logic of creating forms for configuring Policy using micro-service policy schema (in this confluence it's called Policy SDK)
    • Clamp should use Policy SDK to create generic form out of saved micro-service policy schema.

  8. Action Policy configuration (CLAMP)

  9. CL submit (CLAMP)

  10. CL deploy (CLAMP)
