Goal

• Understand the various use-cases
• Common Development Patterns
• Development Best Practices to allow all to be
  developed at will.
• All the scenarios can be solved using a common
  approach that promotes reuse
• Demonstrate solution without custom code

Agenda

• Batch to Real-time
• Remote Information Access/Distribution
• Respond to Real-time events
• Conclusion

Batch to Real-time
Challenges

• Interaction mismatch
• Existing channels using Batch, backend real-time
• 24 hour batch cycles causing competitive issues
• Caused by businesses becoming 247
• Single error causes whole batch to be rejected,
  no time for reprocessing
• Same data sent multiple times to different
  backend systems
• Maybe over distributed environment

5
Scenario Daily Batch of Account Information

• 24 hour cycle
• Same data fed to all databases
• Tight coupling of database schema to transport

Breaking Down the Problem for Developers

• Breakdown solution into separate
  problems/projects
• Projects scoped to tasks and visibility
• Two types of project
• Connection hides connectivity implementation to
  Back end
• Mediation provides logical entity on the ESB

Connections and Connection Project

• Implement each individual method as an ESB
  process e.g.
• AddAccount
• DeleteAccount
• Hides Underlying Platform from other ESB Services
• Therefore can change platform implementation but
  ESB remains the same

20
Deployment

• Connection services located near connected system
• Entity services located in 1.. number of
  locations based on access.

21
Conclusion Batch to Real-time

• Targeted projects based on developers skills and
  knowledge
• Artifacts are specific to context of usage not
  the overall problem
• This will allow reuse

22
Agenda

• Batch to Real-time
• Remote Information Access/Distribution
• Respond to Real-time events

23
Remote Information Access/Distribution

• Leveraging artifacts from Batch to Realtime
• Routing patterns used
• Content Based Router
• Recipient List
• Aggregation techniques
• Data Validation and Enrichment

24
Remote Information Access/Distribution

• Challenges
• Provide external systems and users with
• Single access to read/write across multiple
  back-ends
• Back-ends may change during project and over
  time.
• Providing support to multiple teams
• Portal/UI development team need interfaces today
  to generate Look and Feel
• Back-end team maybe changing applications at the
  same time

25
Scenario Portal to End User

• Providing single view of all data (Read)
• Real-time update of backend (Write)

35
Respond to Real-time events

• Event based integration
• Process is implicit rather than explicit
• Federated Deployments
• Lower cost of integration
• Dynamic Deployments
• Applications/Services plugging in/out ESB

36
Solution Consists of 3 items

• Event Backbone
• The ability to move events to various
  applications
• Event Consumer
• Proxy to the actual application's that are
  consuming the events
• Note this would be in front of Apama/BPEL etc
• Event Producer
• How events are sent to the Event Backbone

37
Event Backbone

• Simple ESB process allows simple VET in channel
• Decouples topic of publisher and consumer
• Channel unaware of consumers
• Consumers can be changed with no affect on the
  channel

38
Event Consumer

• Proxy to consuming application
• Consumes and directs events as required
• May add transformation to move from canonical
  format to target
• Entry point into ESB process is a MultiTopic
• Allows multiple event types to be consumed with
  NO application logic change
• Proxy maybe reloaded on behalf of the consuming
  application.
• Therefore application does not need to be changed

Event Consumer

Event Router

• Router of On-Ramp to Event Backbone

41
Agenda

• Batch to Real-time
• Remote Information Access/Distribution
• Respond to Real-time events

Summary

• One set of deployments for multiple project types
• Reuse of artifacts to reduce implementation time

43
Conclusion

• Artifacts built for one solution can be reused
  across solution types
• Little to no code is required
• ESB supports both SOA and EDA paradigms
