Simple Cloud Usecases

[David Snelling <David.Snelling@UK.Fujitsu.com>]

Folks,

As promised here is the start of a thread on use cases for Cloud  
interactions moderated (in any way) by Symptoms. I suggest we limit  
this thread to the use cases themselves and discuss them in a separate  
thread to avoid confusion (Jeff thanks for the notes) NB: I merged 2  
and 3 from the call and number 3 is a new one.

Use Case 1: Automation of Increased Provisioning

- Provider contributes (and publishes) a Protocol to add additional  
resources (VM, etc).
- Consumer contributes Syndromes (including signature based on the  
Symptoms he will emit) for detecting poor customer response time;
- The provider knows nothing of the consumer semantics and vica versa.

Use Case 2: Automation of Decreased Provisioning

- Provider publishes a Syndrome (including signature based on Symptoms  
he will emit) for detecting multiple Idle VMs allocated to a given  
consumer.
- This Syndrome also includes a Protocol for decommissioning the VM  
within the environment.
- Consumer takes the published Syndrome and Protocol (possibly  
modifies parameters specific to her needs, such as VM shutdown  
process) and adds this to the catalogue.

Use Case 3: Green Policy Management

- The Provider publishes a Symptom relating to the current CO2 burn of  
the customer's current computational estate.
- The consumer can then simple run a Symptoms diagnostician  
(internally or hosted/provided by the provider) to modify her QoS to  
keep CO2 below some policy determined level.

More later. Keep your thinking caps on over the weekend.




Take care:
