Woa defintion

• Web-oriented architecture (WOA) is a type of software architecture that is designed to be used for website and Web applications.

• It builds on service-oriented architecture (SOA) by adding support for Web-based software application and services.

• The key difference between SOA and WOA is the use of REST APIs by WOA instead of SOAP by SOA.

• No! • WOA is much more than REST! • REST is just the foundational architectural style for WOA.. • WOA is really a set of best practices for designing Web

applications • WOA includes:

– a set of consumption models – a set of widely-used standards and technologies for data

representation, data exchange and portability

• Identity, security, Web applications model, new distribution models are not accounted for by REST alone either.

Is woa just rest?

• WOA clearly offers a number of advantages to traditional SOA. – improved service consumption models that are:

• less expensive

• Less time consuming to use

–link architecture to drive information discovery, leverage, and analysis.

–The profound business implications of open web APIs

Woa vs soa

• The WOA approach is not ideal for every scenario.

• For the enterprise architecture, no one approach will fit all needs.

• Most enterprises have the inevitable mix of the following:

–legacy applications

–existing investments in SOAP-style SOA

–point-to-point integration infrastructure

• true pure-play WOA will be all but nonexistent.

Should woa replace soa?

How woa adds value to

soa

• WOA is a way of implementing SOA by creating services that are RESTful resources.

• Woa dramatically simplifies things over the traditional WS-* approach.

• WOA resources are stateless and self-descriptive.

• Hundreds of companies have opened their SOA to the Web - Most are using WOA models for this.

WOA = SOA + WWW + REST

Trigger for web apis

• The significant shift came when smartphones became mainstream.

• Mobile application ("app") development became commonplace and accessible to a huge audience of developers.

• apps can rarely do much on their own.

• They need to interact with the world of data around them.
