4 WHAT IS SOA | DEFINITION

• SOA = Service Oriented Architecture

–

An architecture based on services

–

A services gives access to a capability

• Key features of a service

–

Interface, contract, implementation

–

Consumer, provider, registry

–

Interoperable, standards

–

Idempotent

–

Isolated

Service

“Something useful a

provider does for a

consumer”

1 BIG LASAGNA OR SEVERAL SMALLER ONES?

EXAMPLES | SOAP & RESTFUL INTERFACES

<wsdl:service name="OrderService">

<wsdl:operation name="orderProduct">

<wsdl:input message="order:OrderProductRequest"/>

<wsdl:output message="order:OrderProductResponse"/>

<wsdl:fault message="order:ProductNotInStockFault"

name="ProductNotInStockFault"/>

</wsdl:operation>

<wsdl:operation name="cancelOrder">

<wsdl:input message="order:CancelOrdeRequest"/>

<wsdl:output message="order:CancelOrderResponse"/>

<wsdl:fault message="order:UnknownOrderFault"

name="UnknownOrderFault"/>

</wsdl:operation>

</wsdl:service>

MICROSERVICES

Focus on:

• Business capabilities

• Independent and responsible teams

• Continuous and automated delivery

• Separate deployable units

• Intelligent services

• Tendency to build code instead of reusing

tools

The same or different from SOA?

• It depends  (MSA = SOA + best practices)

• BPM tooling because the process is deterministic

• CRM services are implemented using the existing CRM system

• Billing and Transport Services are implemented in ERP system

• DMS services are offered by a DMS

• ESB is used to expose services

SOA SUITE HAS MATURED …

10g to 11g: Lots of new features & products, but also disruptive change

• New architecture by introducing SCA standard

• WebLogic Server instead of OC4J

• AquaLogic Service Bus instead of OESB

• SOA and BPM both new products

11g to 12c: Evolution instead of revolution

• Same architecture (SCA), same container

• Evolution of existing products

Oracle Confidential – Internal/Restricted/Highly Restricted

Cloud Integration

• Cloud Adapters

• Cloud Adapter SDK

Internet of Things (IoT)

• Event-processing

enhancements

• Insight in events (Stream

Explorer)

Developer Productivity

• Integrated Server

• Unified IDE and Console

• Debugging

… AND STILL INNOVATING

Mobile Enablement

• Native support for REST

and JSON

• API Management

• REST APIs

New Functionality

• Managed File Transfer

• ACM Enhancements

• Enterprise Scheduler

Business-User Friendliness

• User-friendly Rule editing

• BAM improvements

• Integration Cloud Service

4 DEMO | ORDERSERVICE

OrderService - Save Order

• New order is communicated using event

• Order information is stored in database

OrderService - Retrieve Orders (bonus)

• RESTful interface (GET)

• Orders are retrieved from database

• Create in JDeveloper

• Deploy to integrated SOA Suite

• Test using Enterprise Manager

• Monitor using Enterprise Manager

CONCLUSION

• Oracle Fusion Middleware 12c

–

Complete stack (including items like BAM, Service Bus and OEP)

–

Integrated

–

Based on standards

–

Moving to the Cloud

BEST OF BREED | FEASIBILITY

• Standards

–

Building blocks need to be integrated with each other

–

Enterprise Service Bus makes that easier

• Development

–

Having multiple development environments works in big organizations,

not in smaller
