[ogsa-wg] Service creation in OGSA?

[Andrew Grimshaw]

Dave,

A very good question. We are working on just this problem at uva - but think
a broader discussion is in order.

Subject: [ogsa-wg] Service creation in OGSA?

 

Dear OGSA WG,

 

I have an action from the OGSA Dqta WG to ask you about service creation.
When creating services in OGSA, how does the client specify the following
properties:


- Lifetime of Service
- (Storage) Size
- Default QoS requirements 
- Default (security) policies
- Service Location (on which Server say) 
- Provisioning

 

Do you have a common pattern for service creation, or common definitions of
the above items?

 

Currently we are assuming the existence of factory services that can create
shorter-term services.  E.g. in data transport, the long-lived service will
create a short-lived service that manages the actual data transfer.  Clients
will send control messages to the shorter-lived service.

 

This seems similar to the pattern originally encoded in OGSI.  Is it still
the OGSA-approved way to manage service creation?

 

Best wishes,
