Subject: RE: [soa-rm-ra] Re: notes from today's call on SOA management
Actually not quite. Different QoS will require different service deployment and
consequently end points. Now its up to the service provider to define them as
two different services or two different endpoint. From: mpoulin@usa.com
[mailto:mpoulin@usa.com] I was reading the section about service description (for my
current work) and found a statement, which I am not sure how to understand: 2004 Recall, more than one service can access the same underlying
capability, and this is 2005 appropriate if a different real world effect is to be
exposed. Along these lines, one can 2006 argue that different QoS are different services because
getting a response in one 2007 minute rather than one hour is more than a QoS difference; it is a fundamental 2008 difference in the business function being provided. 2009 As a best practice, a criteria for whether a service is
appropriately scoped may be the 2010 ease or difficulty in creating an unambiguous service
description. To my understanding, the statement "it is a fundamental difference
in the business function being provided." is simply wrong! More
accurately, it is very programmer's perspective: a business function is the
same in USA and in Africa, performed by a laser or a pistol... Function is
function. If one consumer wants the business service response in 1
min while another consumer prefers it in 1 hour, function does not change because of
this. QoS makes sense only in the context of the Service Contract.The
statement saying that "different QoS are
different services" is a nonsense - it is rather a
good or bad service, not a different service (this politically correct service
of "different abilities" is a lie to yourself). - Michael -----Original Message----- Thanks Ken, Gentlemen – I’m sending my rough notes and will clean up for
public posting. Michael – note definition of service management and agreed
preference not to define management service. <notes> Management is a process of controlling resources in accordance
with the policies and principles defined by Governance. Boris: service mgt is the process of managing services. Rex: OK. People often think of service mgt but it is management of
services they are talking about. Boris: service mgt is the implementation Rex: part of mgt is service mgt; service mgt in another paragraph Boris: organizationally no separate mgt layer Rex: no, is separate layer; service mgt is one responsibility
(highly specialized) Boris: service mgt is not management. Service management is
the process of managing the services, not managing the people. Is managing just managing people (Boris)? Ken says no. Rex: service mgt as composite noun is service whose function of
mgt. Separate thing is mgt of service. Ken: wouldn’t that be mgt service rather than service mgt? Boris: one of the facets of service mgt is setting up mgt
services. Rex: OK Management service: Rex: function provided either within service automatically or
provided by service provider to manage service actively, i.e. looks at it every
day. Boris: getting into overloaded terms. Ken: IT or business service? Rex: mostly IT but monitored by people. Management of
service within service or management from outside. Service management: Boris: process of proactively monitoring and managing service
behavior. Rex: that can apply to multiple services (stuff above on mgt
service was in context of single service) Boris: process of proactively monitoring and controlling the
behavior of a service or a set of services. Can be manual or automated. Service management is the process – manual, automated, or a
combination – of proactively monitoring and controlling the behavior of a
service or a set of services. Agreed: let’s not define management service because we run into
all the complexities of what is meant by service. </notes> --------------------------------------------------------------------------- Dr. Kenneth Laskey MITRE Corporation, M/S
