Introduction to Services and SOA

From components via webservices to services

• XML as format data interchange
• Advantages and disadvantages of SOA
• The relationship between SOA and BPM

Invoking and using Services

• Data exchange with SOAP
• WSDL: the language for describing the interfaces of services
• Invoking services using REST
• Comparison between SOAP and REST
• Is JSON more efficient than XML?
• What is a compensating transaction?
• UDDI and WSIL for discovering services
• Dealing with the semantics of interfaces

Orchestration of Services

• Automating business processes using BPEL
• Other languages for orchestration, such as IBM's WSFL, BPM's BPML and Microsoft's XLANG
• What is BPEL?
• Overview of commercially available BPEL-engines
• Differences between orchestration and choreography

The Enterprise Services Bus - a new Generation of Integration Products

• Message queuing as transport layer
• Differences between EAI and ESB
• Overview of ESB's, including Axway, CapeClear, Cordys, Fiorano, IBM, InterSystems, JBoss, Magic, Microsoft, Mule, Oracle, PolarLake, SAP, Software AG, Sonic, and Sun

SOA Governance

• Different areas of SOA governance: interface and version management, service management, monitoring, service level agreements, and security
• Services management for auditing, logging and billing of services
• How do service management tools operate?
• Specifying and enforcing service level agreements
• Overview of SOA Governance products
• Different forms of security: encryption, authentification, authorization and firewalls

The mashup for developing composite applications

• From customer mashups to enterprise mashups
• SOA and mashups: a perfect marriage?
• Using mashups to create applications on the rock solid services of the SOA
• Developing applications for the ‘long-tail’ with mashups

SOA and Business Intelligence

• What exactly is Business Activity Monitoring?
• SOA and Operational BI
• BPM and the relationship with Key Performance Indicators
• The data warehouse as a data source for services

DAY 2

Introduction: From web services to service oriented architectures

• The business advantages of SOA
• From monoliths via integrated systems to decomposable information systems
• Why is XML ideal for exchanging data?
• Overview of the standards for web services, including SOAP, WSDL, UDDI, WS-Reliability, WSDM, WS-Security and BPEL
• The development of SOA with an ESB
• Alternatives for an ESB; application server, hub-and-spoke integration broker and message oriented middleware
• Overview of the market of ESB's, including CapeClear, Cordys, Fiorano, IBM, InterSystems, SeeBeyond, Sonic and SpiritSoft

Planning the SOA Project

• How crucial is management commitment?
• Criteria for selecting a design approach: top-down, bottom-up or outside-in
• Composite services as bridge between basic and business process services
• Criteria for selecting products
• Designing a global architecture
• A modelling technique developed by David Chappell to design SOA's
• Three levels in the architecture: the products, de connections, and the services

Designing the SOA

• Design rules for the interfaces of individual services
• From parameter to document oriented interfaces
• Three levels of services: basic, composite, and business process
• Aggregating small, data oriented services
• In which language should aggregations be written: Java, C#, XSL or BPEL?
• The influence of interfaces on network traffic
• XSL and XQuery as languages to transform XML documents
• Studying the legacy applications – are they suitable as a foundation for services?

Guidelines for designing a loosely coupled architecture

Designing basic services

• Four categories of basic services: query-centric, update-centric, logic-centric, and transaction-centric
• The role of XSLT and XQuery for retrieving data
• Design guidelines for compensating services
• Transformation, compositions, and cleaning below the SOAP line
• The impact of interfaces on network traffic
• Bypassing the application yes or no?
• Accessing the data warehouse or the operational data store
• How useful could federation servers be in developing basic services?

Designing composite services

• Composite services to bridge the gap between basic and business process services
• Which development language will we use?
• Design guidelines for aggregating basic services

Designing business process services

• Introduction to BPEL - the standardised language for orchestration
• Combining data from different systems: with BPEL or in a service?
• Should BPEL or the service access the database?
• From BPML to BPEL
• Should we start with identifying the Key Performance Indicators?

Transaction support in the SOA

• Existing standards for transaction management, such as XA and DTP, are failing
• New standards for web service transactions: BTP, WS-Transaction and WS-CAFS
• What is a compensating transaction?
• Overview of stand-alone Business Transaction Manager's from Arjuna, Atomikos and Choreology

Summary and conclusions

• The future of the service oriented architecture
• The relationship between SOA and other IT topics
• General recommendations for the introduction of a SOA
