Merger & Acquisition by
Management and Automation A Use Case Proposal for DCML Andre Kramer, Citrix (R&D) Ltd 6th June 2005 Following the predictable industry consolidation trend, the agile,
technologically innovative, entrant YGene was
acquired by the larger XGenetics. Y, though an early
adopter of Grid computing technology, lacked the IT process maturity of X,
which uses ITIL to deliver IT as a service. Here X was leading, due to its
advanced IT management automation, based on the OASIS DCML framework. Two challenges presented themselves: Y employees, contractors and
partners had to be migrated to X’s IT systems. This involved a manual audit of
all accounts at Y, clarifying the “role” each user had in the system and
constructing a DCML (variously known as Data Center Markup/Model language or Datacenter
Configuration Management Language) model describing
these high-level business relationships, translating these into equivalent
serviced roles in the new joint organization. This document (i.e. the model of the joint IT system) was submitted as
input to X’s service provisioning systems, which automatically determined the personalised
services required by each “new” employee and partner. This derived information
was stored into, and used to update, X’s DCML-based CMDB (ITIL Configuration
Management Database). Note that, this caused new user profiles to be created
and likely future loads to be determined, resulting in service software
installation (including licensing updates etc) and servers, networks and storage
(virtual and or hardware) to be provisioned. Company X had done such M&A
before, so knew the value of DCML, as a model of its data center
operations and its good integration with high level ITIL services, facilitating
automation of service life cycle management. The second challenge was a reverse of the top down service provisioning
problem. Y’s Grid operated over a large collection of heterogeneous systems
(different hardware, software and even organizations). Only a schematic view of
the “virtual organizations” formed on the Grid existed (on the back of an
envelope). Y’s admins, with
help of X’s “data center automation experts” (a new recognized IT discipline) were able to
use diverse distributed systems discovery and management tools to obtain configuration
data for the Grid’s resources. However, the collected
information was in multiple (pre-DCML, of course) formats. Different virtual and real Grid components and their management systems
use diverse modelling approaches (WSDM, CIM, UML and other object models, as
well as relational and other more basic (resource/attribute/value) tables, as
well as ad-hoc models). Such model data were included in a DCML document as
legacy models, and were initially referenced from DCML statements and subsequently refined
(tool and manual conversion to DCML model schema), until the admins
could claim control of the resulting integrated computing resource grid. The resulting refined description was stored in the central CMDB and
represented the joint companies “virtual data center”.
At this point it became the central locus for all IT change management. The resulting joint organization’s IT operated in an automated
service based manner. The fact that large parts of the resulting virtual data center was outsourced, as services provided by “utility” computing vendors, or contributed to “virtual organizations” spanning the research Grid, did not concern
anyone, as the DCML model was owned, change controlled and stored at XY. Subsequent
incremental changes used the same update mechanisms (change notification, rules
etc, effectors etc) that the “bulk” updates utilized. Having one solution (DCML)
which can address and span both the top down and the bottom up IT management
processes, in a single framework was a major winner for the Merger & Acquisition by Management and
Automation, one that played a large part in making the joint company a
success. |
