Why Legacy Modernization

• Cost balance of legacy maintenance vs. new capabilities

• Islands of information• Fragmented and inconsistent

data• Inflexible architecture

• Business builds processes around legacy systems

• Business process change takes years

• Constituencies demand modern applications

• Process improvement and agility • Multi-channel information flow • Competitive forces, regulations, cost

restructuring

SOA is not the Total Answer

• SOA is about architecture • Does not implicitly improve governance,

IT strategy, or business alignment• In practice is often lead by IT architects

with little business input or impact • Top-down, strategic SOA has been

disappointing and most likely on hold due to economics

• There is more to building modern application than SOA

• Total modern architecture includes SOA, BPM, data management, event processing and Web 2.0 technologies - plus flexibility to accommodate future technologies

Legacy Data Management

The SOA Information Gap

“SOA by itself does nothing to address the question of how data should be managed within this architecture. ... data remains fragmented despite the best efforts to rationalize it. This issue is motivating the creation of a new class of middleware that Forrester calls the information fabric.”

The Forrester Report Information Fabric: Enterprise Data Virtualization

"You will waste your investment in SOA unless you have enterprise information that SOA can exploit."

Gartner

SOA and BPM

Business Process Management and Workflow

• The term Business Process Management refers to activities performed by businesses to optimize and adapt their processes.

• Although it can be said that organizations have always been using BPM, a new impetus based on the advent of software tools which allow for – Direct execution of the business processes without a costly and time

intensive development of the required software. – In addition, these tools can also monitor the execution of the

business processes, providing managers of an organization with the means to analyze their performance and make changes to the original processes in real-time

• BPM has a tight link to componentized and service oriented IT architecture

Workflows implement business processes

Workflow engine navigates the network of activities

Typically invoking automatic (service choreography) or manual activities

Mostly visual programming/modeling

GUI is in general form-flow based and supports RIA

Process Oriented Approach

• Process modeling - a new approach to application and service development – a radical change from traditional application development

• Key benefits:– Visibility & commonality of processes– Processes as the common ”language” between IT and business– Cost reduction through flexible automation – typically 20+%– Process optimization and streamlining across applications and the

enterprise– Continuous, nondisruptive process improvement – Monitoring provides understanding of where the employees spend

their time– Faster implementation of changes in processes – typically 30+%– Optimizing skills usage in the business– Excellent match & synergy with SOA/ESB

SOA, Web 2.0 and Cloud Computing

A set of new Web-based technologies, that enable the web to become a platform for dynamic content creation and distribution

A new generation of web-based communities and hosted services — such as social-networking sites, wikis, and social-tagging — which aim to facilitate creativity, collaboration, and sharing between users.

How can we get the best of both worlds?

Mobility in the Enterprise Architecture

(1993) “The revolution kicked off by the arrival of Intel's Pentium chip for desktop PCs. It was a leviathan, a monster of computing power that ticked along at 66MHz, and enabled all sorts of powerful applications to run on your Windows 3.1 PC. Compared to the chip Marvell has just unveiled, the original P5 was a crock. Because the Armada 628 hums along at 1.5GHz (over 22 times faster).”

Pervasive Computing and Networks

Limited: bandwidth, memory, storage Large data sets: paging, parsing, filtering Support native runtime features (graphics,

camera, GPS) Rich user experience over slow data

connections Connectionless environments Security and transactional state regardless of

connection Context awareness and digital memory Agents, rules engines and events RFID, sensors and actuators

Pervasive computing is coming. How will your architecture support it?

Events and Complex Event Processing

“The goal of CEP is to enable the information contained in the events flowing through all of the layers of the enterprise IT infrastructure to be discovered, understood in terms of its impact on high level management goals and business processes, and acted upon in real time.”

Professor David LuckhamStanford University

Correlated Events Trigger Processes

Starting down the Service Oriented Path

Architecture Modernization Challenges

• Spans multiple technologies

• Design requires multiple views for business, analyst, architects and developers

• The role players in the design process require new skills

• Tools and techniques are immature

Quick Start Rulebook™ Methodology

• Develops SOA strategy and roadmap• Establishes the SOA competency center

organizational and maturity model• Define governance model for design,

asset management and operations • Develops SOA reference architecture• Addresses SOA project orientated

methodology• Establishes the operations and quality

assurance strategy processes and procedures

• Supported by design patterns and reusable components

• Codify common design patterns – e.g. the Exception Handler

• Optimize the operational environment

Quick Start Framework

• QSF has several layers of abstraction– Presentation – Proxy/Gateway – Messaging– Orchestration– Adapters

• Gateway– Service Levels and Metering – Protocol Level Abstraction– Version Management– Dynamic Routing– Security– On-Demand Encryption

• Messaging– Communication layer between other

components of QSF• Orchestration

– Service and Business process orchestration built on products from IBM, TIBCO, Oracle, OSS

– Exception Handling and Audit Logging • Adapters

– Backend abstraction– Consolidation of various protocols into a known

uniformed format and behavior

Architecture Case Study

• Business Process Improvement with RIA, Business and Information Services

• Automates sales role in the overall order process

• Features: Visibility to product availability, automated cost estimates, collaborative (with customer) proposal process, capture of information to eliminate downstream duplicate data entry and facilitate process hand-offs

• Key benefits: Process improvement and automation results in time savings for sales leads to increased sales

• Cost estimate and ROI
