The document discusses new approaches to integration in a cloud computing world. It outlines the evolution of core integration patterns from 1997 to 2011 as data, services, and processes have become more fragmented with the shift to cloud. It emphasizes that integration and the cloud have often been an afterthought, and that successful integration in the cloud starts with understanding business needs, existing systems, and data semantics. It also addresses some of the key technical challenges around semantic mediation, transformation, governance, discovery, and connectivity when extending systems and services to the cloud.

7. C ORE I NTEGRATION PATTERNS 1997
• Simple information exchange.
• Adapter management.
• Intra-enterprise.
• Process focused.
• Emerging use of services.

8. C ORE I NTEGRATION PATTERNS 2003
• Simple information exchange.
• Use of services.
• Use of processes.
• Use of federated integration.
• Leveraging transactions.

9. C ORE I NTEGRATION PATTERNS 2011
• Data integration.
• Use of SOA patterns.
• Use of standards.
• Use of open source.
• Movement to the hybrid cloud.

15. T HE B ASIC C ONCEPT
• One can consider cloud
computing the extension of
SOA out to cloud-delivered
resources.
• The trick is to determine
which services,
information, and processes
are good candidates to
reside in the clouds, as well
as which cloud services
should be abstracted within

SOA.

16. Getting Things Done

17. U NDERSTANDING THE P ROBLEM
• Cloud providers must integrate with existing
enterprise systems to become more valuable.
• However, existing internal integration needs to exist
to ensure:
– Production and consumption of structured information
– Semantic mediation
– Security mediation
– Service enablement
– Firewall management
– Transactional integrity
– Unstructured data
– Holistic management of the complete integration chain

18. REMEMBER, THERE
ARE A FEW
TECHNICAL ISSUES
• Semantic and metadata management, or, the management of the different
THAT YOU MUST
information representations amount the external services and internal systems.
• Transformation
ADDRESS… and routing, or, accounting for those data differences during run
time.
• Governance across all systems, meaning, not giving up the notion of security and
control when extending your SOA to the global SOA.
• Discovery and service management, meaning, how to find and leverage services
inside or outside of your enterprise, and how to keep track of those services
through their maturation.
• Information consumption, processing, and delivery, or, how to effectively move
information to and from all interested systems.
• Connectivity and adapter management, or, how to externalize and internalize
information and services from very old and proprietary systems.
• Process orchestration and service, and process abstraction, or, the ability to
abstract the services and information flows into bound processes, thus creating a
solution
