The mistake is that people often see SOA as a technology


Scope drives architectural considerations

HeterogeneitySpan new service-enabled applications as well as existing applications

ScalabilityProvide the performance expected of enterprise systems while easily accommodating changes in demand

AvailabilityIsolate applications from faults resulting from server and communication failures

FederationProcesses will interact with services spread across an organization, and between organizations

FlexibilityAllow the organization to change processes, rules, data mapping and relationships between applications with minimal effort and disruption

Visibility and controlManage and monitor the infrastructure as well as the processes and services deployed within it

This cloud MUST be addressed – it needs:

Typically deployed inside a single company – inside the firewall

Services and processes cannot seamlessly span integration brokers

Proprietary technology is too complex and costly for distributed roll-out


Application Server ceiling

PORTAL EIS

Lack visibility and control of cross-cluster process

Exceptionally good for hosting business logic in a component model and serving web pages

Services and namespace do not seamlessly span clusters

Changes require disruptive coding and/or deployment

Large footprint and administrative overhead drive excessive costs in distributed deployment

Hiding implementation details enables reuse

XML-based data easily exchanged

Designed for remote access, across heterogeneous platforms

Can be easily passed over HTTP(S), JMS, CORBA, Sockets, MQ, RV and almost any other messaging layer

Web Services

Is it reliable, scalable and secure?

How do you change business processes?

How do you manage and monitor distributed services?

What about mediation and process flow?

But Have We Solved The Whole Problem?

Web services are interoperable communications stacks and don’t offer routing, service deployment, management, format transformation, guaranteed delivery, etc.

You are building standards based spaghetti !

Map and bind services, processes, and IT assets

Sonic ESB makes it easy to connect, mediate, and control services and their interactions


Connect IT resourcesBind into a uniform service model

Connect old and new– 208 packaged applications

– Most language platforms

– Web services

– Relational databases

– Object database support

– B2B collaboration

Provide uniform service model– Event Driven Architecture

– Separate service implementation from service invocation

Connect


Mediate service interactionsFlexibly combine and enrich business services

Mediate

Move data with configurable qualities of service

Pluggable authentication, authorization, cipher suites

Flexibly configure routing and process flow

Transform and enrich data

High Availability at software layer


Control services and infrastructureFrom any point on the network

Global service configuration

Global service discovery

Dynamically configure, deploy and scale hosted services and communication backbone

Define and alter process flows, routing, quality of service without hubs

Track services and their interactions to gain visibility and control

Dynamic business and also technical SLA monitoring and alerting

Filling in the SOA “white-space”


Case Study:The BAA Terminal 5 Project


The reality of serving 35 million people per year

37 million man hours to build T5

6.5 million cubic metres of earth works

15,000 cubic metres of concrete per week

16 major projects, 100 sub-projects

Sub projects cost between £30M and £150M

60,000 people involved in the build

The IT infrastructure must operate entirely new level of

speed, efficiency and availability – and work with existing

legacy systems that already manage 122M people/year


The IT landscape – must be integrated

6000 display systems, 400 COTS apps,197 line of business apps, 35 operationalIT platforms, over 1000 servers

One hour server failure has Europe-wide impact on flights, more than one hour has global impact

One off £250M fine for late delivery of T5


BAA – The Strategy

“… our strategy is to minimize the interdependencies between products, using open standards to increase operational flexibility and make sure that applications are responsive to change.

Therefore a Service Oriented Architecture approach is inevitable”

Nick Gains Head of IT BAA


What are the challenges?

The Devil is in the detail…


How do you manage a project this big?

How do they leverage their existing IT portfolio?

What will this cost?

What would be the impact of– Changes?

– Expansion?

– New security threats?

– Regulation changes?

How will they accommodate future requirements?

Business Process Definitions


Strategy Versus Tactics

This is how BAA are making T5 a success

Everything is broken down into manageable tasks

Architecture governance (this is key!!)

Evolutionary project management

– NOT Waterfall project management

An IT back-bone and architecture from

the very start

Industry patterns are being heavily

exploited – Sonic lead the way

What makes some ideas work where others fail?

Sonic ESB

Lower maintenance costs, greater flexibility,increased visibility,business process flow driven,highly available infrastructure,standards based


BAA – The Strategy “Our challenge was to find a platform that would work well in

our very demanding environment, and could orchestrate the services that will drive T5 operations. Sonic Enterprise Service Bus is a very natural fit.”

In addition: “Heathrow is the gateway to the UK, downtime of even a few minutes can cause disruption across all our operations. Our experience is that hardware fault tolerance alone is not the answer. The Sonic ESB Continuous Availability Architecture™ provides us with a distinct advantage."

Nick GainsHead of ITBAA


In this interactive technical workshop, you will learn how service-oriented architectures (SOA), enabled by the enterprise service bus (ESB), help solve the integration challenges faced by most organizations.
