Who We Are

Friday, May 17, 13

What is SOA

• System Architectural Pattern

• 3 Parts - Provider, Broker, Requester

Friday, May 17, 13

Service Provider

• All about Data

• Creates a web service

• Provides access to data layer to the Service Broker

• Determines which services to expose

Friday, May 17, 13

Service Broker

• All about routing. Think Traffic Cop

• Responsible for making the service available to any Service Requester

• Connects the Requester to the Provider

Friday, May 17, 13

Service Requester

• Requests the desired web service form the Broker

• Calls services from the Provider once connected

Theory & Principles of SOA

• Interoperability on different systems over a communication protocol

• Service Statelessness

• Service Encapsulation

• Service Granularity

• Service Discoverability

BreweryDB & SOA

Friday, May 17, 13

BreweryDB 1.0

• Website with API

• Maintainability - Tightly coupled

• Data Model was small

• Data structure inconsistencies

Friday, May 17, 13

BreweryDB 2.0 Requirements

• API First

• A single way for everyone to consume the data model

• Separate display from the data model

• Consistency in all responses

Friday, May 17, 13

BreweryDB SOA

• Service Provider is our Data Model

• MySQL + Elasticsearch + Models

• Service Broker is our API

• Endpoints

• Service Requesters are everyone that uses BreweryDB

BreweryDB Data Model

• Service Provider

• Validation

• Consistent input and output structure of data

• Decoupled from response format (XML, JSON, PHP)

• Decoupled from access control

• Builds data relationships

BreweryDB API

• Service Broker

• Authentication

• Return formats

• Authorization

• Resource routing

• Error handling

Friday, May 17, 13

Designing an API

• Endpoint structure

• Error handling

BreweryDB Consumers

• Service Requesters

• Single interface to our data

What we Learned about SOA

• Maintainability

• Allows for fast iterations

• Initial up front work is expensive

• Not always the answer

Hurdles

• Enumerated Fields

• Website Authentication

• Emails
