The CIO‘s ESA Brief

In a nutshell: The Essentials of SOA and ESA and why you need to rely on it


ESA or not ESA, that is the Question

Whether it i s nobler in the mind to suffer the sl ings and arrows of outragous fortune or to take arms against a sea of troubles

and by opposing end them.[W. Shakespeare: Hamlet , Prince of Denmark]

Abstract

Enable a CIO to judge the r isks and chancesAutomation with SOA is not rocket scienceSOA will soon prove inevitable for any IT SAP’s ESA steers away from the “big bang”SAP ESA is a mature framework for EAIAllows a step-by-step migrationBenefit from 20 years of EAI experienceLearn business cases for agile ESA adoption


What Is SOA?

SOA Transforms software applications into services that that external applications can reuse by provision of common communications

standards and demanding applications to deliver functionality as reusable services.

The Era Before SOA

TodayWildly grown application hybridsRedundant development of applicationsInaccisible data sources

Object oriented ArchitectureDevelop reusable modules

SOACommon interface standardsCommon communication standardsReusable public services


The Promised Wins of ESA

SOA will not only eliminate redundancy but also dramatically enhance data quality, accelerate data discovery and allow for innovative customer services.

Ergo: save money and have a better sleep!

An Analogy: Communities

Communities benefit from public servicesOne road is built for many houses

•Holes for water, phone, electricity digged only once

Traffic rules are compliant•Continent drives right, commonwealth left ...

Vehicles are built with compatible technology•E.g. petrol, tire sizes

Vehicles are operated analogously•Airplanes are steered with wired rudders•some gocarts with pedals but •automobiles are controlled by a steering wheel everywhere

An Analogy: IT habitats

IT habitats benefit from enterprise servicesOne compatible execution runtime

•Programming language compiles to J2EE, .NET, ABAP

Service interfaces are compliant•WSDL etc. expose interface for easy discovery ...

API access is built with interchangeable technology•E.g. DB is accessed via open SQL or ODBC•Services are transported via HTTP etc.

Business Cases

Streamlining Data Flows and InterfacesUsing fewer technology variants

•Enhancing data quality, Optimizing ressources

Business Activity Monitoring (BAM)Real-time discovery of decision support

Process AutomationWorkflow of repetitive tasksEliminate multiple data entry „print-to-type“

InnovationEstablish new web-based businesses („eBay“ ..)


Consolidation of Interfaces

Current landscapes are dominated by wildly grown and loosely coupled interface activities that make efficient resource housekeeping nearly

impossible.

Traditional Application Integration

Proprietary interface formats

Peer-to-Peer interfacesWildly grown over time

Predominently Offl ine-InterfacesE.g. File downloads/uploads

Interface design „on-demand“ onlyInterfaces created from scratch when needed

Steps to Interface Consolidations

Reduce Peer-to-peer connections

Establish common interface formatsMakes messages comparable and programs compatible

Delegate routine works to central servicesE.g. Archiving, versioning, emails, printing, FTP polling

Automate procedures for error handling and data recoveryE.g. handle duplicate messages, target server failure etc.

Benefits from Consolidation

Administration Resources optimzedLess training when all interfaces look alikeError patterns will ressembleSystematic errors will be solved for all

Develop once, use anywhereDevelop customizable componentsAlgos are not only „lab-tested“Eventually reduction of development costsReduction of test costs Higher quality by established components


Business Activity Monitoring

SOA is the pre-requis ite to al low a real-t ime discovery and tracking of business activit ies

Benefits of BAM

Business process transparency

Production process transparencyVirtual clear-case production

Agil ity in business transformationThe earlier you know the quicker you react

Early detection of quality problems

Early discovery of irregularit iesE.g. Change of trends and fraud attemps

Legal security and trackingImmediate information in case of incidents


Process Automation

Automating processes is the e lementary goal of a SOA

Benefits of Process Automation

Accelerate information f low

Uniform Process Flow TrackingGuarantee one form of protocolIntrinsic debugging and testing tool set

Enhance data qualityAvoid multiple manual entriesOn-the-fly data verification

Use innovative data sourcesE.g. RFID, OCR, sampling devices


Innovation Enablement

SOA will build the infrastructure for completely new business that are not possible with traditional means

Where is Innovation

Innovation wil l be a side-effect of SOA

Be creative, surrender to your dreams

Role models: eBay and AMAZON.COM

Innovation may al low a competitive advantage

Innovation means also agi l ityAgility means quick reaction on business demands

Examples of Innovation

Examples:Market places

•Offer your goods in collaboration with your competition via the same one-stop market place portal

Auctions•Offer your special sales through a bidding portal

On demand services•Online order configuration and visualization•Order tracking, document self-service•webcams (clearcase production)•Last minute order changes


Risks

There are few risks in implementing SOA but painful penalties in failing to do so

Risks

Early implementations suffer from immature frameworks

Late adoption can be disastrous

Risks by hesitant SOA implementationInnovation gap to leadersIncapability to deliver (in-time or at all)

Risk through SOAInformation abundanceUncontrolled intelligence disclosureLiability by unmanaged publishing
