investments
Integrating Services into the IT Supply Chain
Services…
Are the most valuable software
investments you make
Have extensive metadata that must
be managed
Don’t exist in isolation
Have broad governance
challenges, similar to other IT
Must comply with standards,
regulations and service levels
Proliferate uncontrollably, unless
part of an architecture
Need to be managed as part of the
overall fabric of IT, not only in
“SOA fabric” Reduce…Reuse…Remix
Governing SOA
SOA requires governance
(cid:1) Reduce, Reuse, Remix
Macro-governance – Build the right things

ALSR + ALER = Full Lifecycle Governance
BEA is the only vendor that provides full registry and repository
capabilities for management of the entire SOA lifecycle.
Design Time
Runtime
Metadata management
strategy is focused on the
management of metadata
across the entire SOA lifecycle
Repository is most appropriate
technology for use during the
design-time stages of the
lifecycle
Registry is most appropriate
technology for use during the
runtime stages of the lifecycle
Registry and Repository bridge
from design-time to runtime
and back

emphasizing design-time software asset management and lifecycle
governance.
(cid:1) Enabler for sharing of rich metadata across BEA products and
heterogeneous environments
(cid:1) Catalogs what has been defined within the enterprise
(cid:1) Manages and governs assets and their dependencies
(cid:1) Enables proactive impact analysis and change management
(cid:1) Provides visibility into asset usage in alignment with architecture
(cid:1) Provides policy management
(cid:1) Measures savings and ROI
Role of ALSR

(cid:1) UDDI v3 based
(cid:1) Manages runtime metadata associated with SOA artifacts
(cid:1) Catalogs what services have been deployed within the enterprise
(cid:1) Serves as a discovery tool for runtime policy enforcement
(cid:1) Bridges design-time and runtime stages of the SOA lifecycle
