TOSCA Scale definition

[Manas Mal <MMal@advaoptical.com>]

Hello All,

 

The TOSCA scale definition as per the auto-scale policy is as follows:

 

12.5.2.1.3 Sample YAML

my_scaling_policy_1:

type: tosca.policy.scaling

description: Simple node autoscaling

properties:

min_instances: <integer>

max_instances: <integer>

default_instances: <integer>

increment: <integer>

 

 

However we have the scalable capability definition of the VDU.

5.5.13 tosca.capabilities.Scalable

5.5.13.2 Definition

tosca.capabilities.Scalable:

derived_from: tosca.capabilities.Root

properties:

min_instances:

type: integer

default: 1

max_instances:

type: integer

default: 1

default_instances:

type: integer

 

So there is a confusion as to which one should be used for auto-scale definition for a VDU?

Please clarify the same.

 

Regards,

Manas
