Event Driven Architecture - Defined

EDA is a style of architecture that enables

Real-Time Enterprise (RTE)

transformation through production,

detection, processing, and consumption of

business events to identify and react to

business opportunities, threats and

anomalies.

Real-Time Enterprise

“The Real-Time Enterprise (RTE) is an

enterprise that competes by using up-to-

date information to progressively remove

delays to the management and execution

of its critical business processes.” - Gartner

EDA Drivers

• Revenue Growth Drivers

• Shorten sales and delivery cycles

• Real-time capabilities to gain

competitive advantage

• Enhance customer experience ->

improved customer loyalty

• Identify and execute up-sell/cross-

sell opportunities

• Cost Reduction Drivers

• Reduce cost by JIT operations

• Boost profitability by faster order

processing and fulfillment

• Eliminate waste through a lean

approach

• Mergers and Acquisitions

• Agility and TTM Drivers

• Monitor, sense, and react to market

changes

• Faster product and service rollout

• Situation Awareness - Real-time

visibility for business decisions

• Technology Drivers

• Loosely Coupled Architecture

• High volume, low latency

processing

• Process and Service interaction

• Partner integration

• Real-time monitoring

• Pattern Matching and Analysis

Application of EDA

Financial Services

Transportation & Logistics

Public Sector & Military

Manufacturing

Insurance

Telecommunications & Services

Algorithmic trading

monitoring

Reponses to calamities –

earthquake, flooding

• Intrusion detection systems

• Military asset allocation

Need to support one or more of:

• High volume

• Continuous streaming

• Sub-millisecond latency

• Disparate sources

• Time window processing

• Complex pattern matching

EDA Maturity Model

Capability Domains Measurement Model

• Eight capability domains – comprehensive coverage

• Domain – A collection of related capabilities

• Model measures maturity and adoption levels

EDA Maturity Model Capabilities

EDA Roadmap Planning

• Plan and manage holistically

– multiple dimensions, multiple

phases and time periods

• Remedy problem areas –

Use EDA Domain Capability

Heat Maps to identify problem

areas and inhibitors to EDA

adoption

• Close Gap – Use EDA

Domain detailed strategies for

closing the “as-is” and “to-be”

gap.

• Improve - You can’t improve

what you can’t measure

EDA Conceptual View

EDA Capabilities

EDA Architecture Sample Principles

• Event driven systems must be loosely coupled.

• Event driven systems must be standards based.

• Business events must be discoverable.

• EDA must be designed to support interoperability and must

complement existing technologies.

• Events must be captured and processed at the most granular

level.

• EDA must focus on supporting and handling business events.

• The architecture must be modular and must support extensibility.

• Event Driven Architecture must enable low latency processing

and be able to support processing of high volume of events.

• Events that are sensitive must only be made available to the

appropriate systems/users.
