What is Web Oriented Architecture

3  

§  A term coined by Nicholas Gall of Gartner, VP Distinguished Analyst in 2006 §  See https://www.gartner.com/doc/797713.

§  WOA == SOA + WWW + REST §  Service Oriented Architecture §  Everything on the Internet §  Everything based on REST

§  In other words it is the world’s most commonly used architecture today by far.

Why does it matter to me?

4  

§  The Gartner Prediction §  By 2014, WOA (REST)-style

services will be in use in 80% of organizations pursuing SOA

§  True? Well it doesn’t really matter, because anyone needs to know WOA.

Why does it matter to me?

5  

§  You can’t just do REST from SOAP or SOAP from REST.

§  Its not just a matter of transformation

§  So, what’s the deal with these ESBs and API Managers? §  No use? J

Why does it matter to me?

6  

§  Now why did I say that? §  SOAP is a flat structure §  REST is a hierarchical structure

Why does it matter to me?

9  

§  Confusion…!!! §  XML is hierarchical too right? What are you

telling me now?

Why does it matter to me?

10  

§  XML is hierarchical, but XML != SOAP §  You can serve XML on REST too BTW.

§  When I said hierarchical, I meant something else §  Every time you invoke a SOAP service, you

invoke it using a Service Name and a Method Name (or you pass an Action)

§  In REST, your API is technically endless, but only if you get it right

§  So, no clear mapping

Why does it matter to me?

11  

§  Need more complication? §  Fine, add it to it everything WWW.

§  How is this complicated? §  Simple, J §  How can you build a SOAP back-end for a

Fileserver?

Why does it matter to me?

12  

§  Do you really need that? No.

§  That’s why WOA matters to you. Its about a world of coexistence.

How can I use this?

13  

§  There are many examples. §  Banks §  Education §  Retail Industry §  Transportation Industry

§  OK, any industry has an example, J.

How can I use this?

14  

§  So, lets take something fairly complex to learn this. Like an IoT Architecture for a Street.

How can I use this?

15  

§  Or something that works all over the place. In my office, at my home, on the road, …

Some Real Examples

Case Study: StubHub – Managing high volumes of data for viral businesses

StubHub needed an API centric architecture to become the worldwide destination for an end-to-end experience for fans

Product  Product  

Challenge •  StubHub was missing out on potential channel of new business

revenue with a looming competitive threat from industry peers and newcomers

•  The solution demanded the development of an API economy strategy, and re-architecting a running business

•  There was a need for a scalable system, which while handling high volumes of data, also has the ability to constantly evolve as an agile system

•  It had to not only be a product, but a platform that can leverage broad third-party developers and businesses to thrive

Solution •  A high performance and scalable API management solutions system

that can handle high volumes of traffic •  A simple lifecycle model that can be customized and extended to

align with the company’s API strategies •  WSO2’s integration suite not only exposes existing capabilities, but

helps to deploy new systems to maximize value, analyze, results, etc.

Case Study: Trimble - Transforming the way the world works through innovative solutions for various industries

Trimble was looking for a connected platform to link many stakeholders via complete centralization

Product  

Solution •  A centralized Trimble Platform as a Service (TPaaS), consisting

of various components available as a service including identity, auditing, transformation and routing

•  Each division, partner and dealer is a tenant in the multi-tenanted platform.

•  Each division has autonomy in creating flexible solutions that use the TPaaS components under their specific tenants.

Challenge •  Trimble has a large number of divisions that cater to various

verticals •  Each division has its own set of applications and customers,

resulting in a diverse set of applications and technologies •  A unified mechanism was required to service dealers, partners

and customers of Trimble, whilst increasing division autonomy, technology management and reducing time to market

Case Study: Al-ELM – Managing Identities and Ensuring Secure Online Transactions

Al-ELM was looking to implement a system that would streamline administration, improve productivity, and reduce costs

Product  

Challenge •  The growth of the Unemployment Assistance Program; the original

project covered one program that enabled unemployed citizens to submit their requests

•  The Saudi government expanded the services to include several programs, which prompted the need to streamline administration to manage 4 million user identities

Solution •  The WSO2 Identity Server proved to be the most flexible and

customizable solution for ELM •  Since implementing single sign-on (SSO) through WSO2 Identity

Server, ELM has been able to significantly streamline the administration of user identities, as well as improve overall user experienceThe benefits also include improved productivity, increased security, centralized management, and reduced cost

•  In production since April 2013, the program SSO system manages about 4 million users with 2,000 login requests per second
