Driving Innovation with SOA

Dave James – Lead CI ArchitectRef: Dr Akram – Bou-Ghannam

Innovation That Matters


SOA Introduction• There has been a lot of buzz and hype -- some factual, some

not so well-founded -- surrounding the opportunities presented by Service-oriented Architectures (SOA) and its implementation as Web services. Analysts have predicted, pundits have professed, professors have lectured, companies have scurried to sell what they had, as SOA products -- often missing the point that SOA is not a product. It’s about bridging the gap between business and IT through a set of business-aligned IT services using a set of design principles, patterns, and techniques.

• ZDNet recently said, "Gartner predicts that by 2008, more than 60 percent of enterprises will use SOA as a "guiding principle" when creating mission-critical applications and processes."

The basics: What is SOA?

… a service?

A repeatable business task – e.g., check customer credit;

open new account

… service oriented architecture (SOA)?

An IT architectural style that supports

integrating your business as linked

services

"SOA impacts every aspect of IT and business.”

IBM SOA

Why SOA now?

To keep pace with global competition:

– “We are taking apart each task and sending it … to whomever can do it best, … and then we are reassembling all the pieces” from Thomas Friedman’s ‘The World is Flat’

The standards and technology are finally in place, with broad industry support

Availability of best practices for effective governance

The necessary software to get started is available today


What Differentiates SOA from Claims Like This in the Past?

Broadly adopted Web services ensure well-defined interfaces.

Before, proprietary standards limited interoperability

Standards

Business and IT are united behind SOA (63% of projects today are driven by LOB)*

Before, communication channels & ‘vocabulary’ not in place

Organizational Commitment

SOA services focus on business-level activities & interactions

Before, focus was on narrow, technical sub-tasks

Degree of Focus

SOA services are linked dynamically and flexibly

Before, service interactions were hard-coded and dependent on the application

Connections

SOA services can be extensively re-used to leverage existing IT assets

Before, any reuse was within silo’ed applications

Level of Reuse

*Source: Cutter Benchmark Survey


SOA Challenges

Governance – Good SOA demands good governance

Complexity – Composing applications of independent and

loosely services increases complexity

Reuse – What do we have and what does it do?

Process – SOA is a new way of thinking and requires

process and process guidance

Team communication – Successful SOA brings LOB and IT closer,

requiring seamless communication


Business Benefits of SOA

Business Driven

Development for SOA

Flexibility and scalability Decreased time to market

Applications designed for change

Productivity gains

Reduced cost

Improved quality


Key Concepts and Definitions – What is a Service?

Service– From a business adaptability point of view

• A service provides a process neutral capability that can be used in one of several business processes concurrently or over time.

– A service is a software component that is described by meta-data, which can be understood by a program. The meta-data is published to enable reuse of the service by components that may be remote from it and that need no knowledge of the service implementation beyond its published meta-data

– The narrow technical definition• A service has a well-defined interface (with a set of messages that the service

receives and sends, and a set of named operations or verbs), an implementation of the interface, and if deployed, a binding to a documented network address.

Web Service– Service that, at a minimum, defines its interface by using the Web Services

Description Language (WSDL) and is accessible by using a protocol that is compliant with Web Services Interoperability (WS-I)


Key Concepts and Definitions – Business & Information Services

Business Service– Service that typically implements a business process or an activity within a

process.

– Belongs to the Business Service Layer (BSL): • A collection of related services for a given business domain (ex. Order fulfillment,

human resources, etc.) that all follow a certain set of conventions and standards relevant to that domain. Services on the BSL could share common:– Business vocabulary and semantics – Elements of Specification – Policies. Ex. Security, SLA

Information Service or Information as a Service– An information service is a service that acts as an abstraction layer between

information consumers and providers for the creation, management, federation, aggregation and access of information.


Key Concepts and Definitions – Enterprise Service Bus

Enterprise Service Bus (ESB)

– A flexible connectivity infrastructure (WebSphere) for integrating applications, services, and information.

• Virtualizes the services that are made available through the bus by managing– Meta-data that describes service requestors and providers

– Mediations and their operations on the information that flows between requestors and providers

> Mediations are the means by which ESB can ensure that a service requestor can connect successfully to a service provider

– Registry: Meta-data is managed through a registry that supports

> Configuration, Connection, Matchmaking, and Discovery of service end-points


Key Concepts and Definitions – SOA+ and ECBA

SOA+

– Service Oriented Architecture Plus (SOA+) is transforming IBM's internal information technology into a Service Oriented Architecture. The plus (+) signifies how it is also enabling the fusion of business and information technology with methods and tools to integrate IBM's people, process, information, and applications into an on demand business. SOA+ is responsible for driving the overall SOA strategy, direction, and coordination for all IBM internal activity.

– SOA+ is the next generation of the Enterprise Component Business Architecture (ECBA).

ECBA

– ECBA has been a business architecture designed to promote IBM on demand enterprise capabilities to quickly deliver business value through increased productivity and automation. It enables business and information technology functions to work synergistically, creating more fully integrated relationships among processes, applications and data.

– ECBA was originally focused on “componentization with services interfaces” of the enterprise application portfolio. It drove componentization activities with business / application domains and promoted the standardization of interfaces as “services” for services and information integration.

– ECBA's Distributed Components are essentially software applications that are accessed through the network via services interfaces, and can be independently developed, tested, deployed, and maintained. Larger systems can be created though the combination of multiple components, and larger components can be represented by several sub-components (e.g., Component-Service Domains).


Key Concepts and Definitions – SOMA and SIMM

Service Oriented Modeling and Architecture (SOMA)– SOMA is a methodology designed to build a complete list of potential services

from a business process and specify those to a level sufficient as input to business requirements and detailed design. SOMA is an analysis technique oriented toward bringing business process insights to a place where the technical roles may start to incorporate the services and components into their designs.

Services Integration Maturity Model (SIMM)

– SIMM is used to conduct assessments and determine level of maturity for an enterprise or line of business and design a plan of action. SIMM helps in:

• Determining current maturity level of integration

• Determining which characteristics are desirable to achieve

• Defining how to achieve them by attaining a new level of maturity.

• Determining whether problems encountered at a given level of maturity can be solved by evolving to a higher level of integration.


Information as a Service


Business Problems

Trusted information is not available when & where needed

Inflexibilities make the business slow to respond to changing requirements

Cost of managing IT is too expensive

The full value of information is not being leveraged


Technical Problems

Information architecture is too complex

Each new process builds expensive custom connections to information

No way to centrally govern information

Can’t reconfigure business processes as needed

Information is a Vital Component of SOA Strategy

Information within SOA efforts is often considered only within the context of specific processes

The most anticipated benefit of business investment in IT is information availability

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