Introducing Mattson ...Hi.. Mattson here.. I am an Enterprise architect
Heard about a webinarfrom WSO2
On making it easy to do Enterprise Integration
Have a few Questionsthough :-(
3
• What is Enterprise Integration?– A two minute definition
• When do you need it?– Importance of an ESB in a nutshell
• Why WSO2 ESB (2.1.0)?– Features & Functionalities in detail
• Who can use WSO2 ESB?– Simplicity and the usability
• Where should I look for more?– Resources & References

What is Enterprise Integration?
5
Enterprise Integration
the alignment of strategies, business processes, information systems, technologies, and data across
organizational boundaries to provide competitive advantage
Definition:- http://www.eiisolutions.net/resource-center/glossary
6
How do you achieve EI?
It is possible to achieve by a good SOA design,but it is impractical,
because we need to inter-operate with legacy systems which cannot be redesigned
Can be achieved by using an ESB
7
So What isESB?
Hey Mattson, it is “Enterprise Service Bus”
Well, I heard about ESB Before
But not so clear about it
8
Let's define it...
Any to any data connectivity and transformation (including Web Services)
built on an advanced, proven, reliable middleware infrastructure
Note:- Just for the sake of a definition :-)

Why WSO2 ESB (2.1.0)?
What is so special aboutWSO2 ESB?
18
WSO2 Enterprise Service Bus
A fast, Light weight, easy-to-use Enterprise Service Bus product
Open source product with commercial support (if required)
Released with business friendly Apache License 2.0
Based on Apache Synapse & WSO2 Carbon Customizable to match the needs of your
Enterprise
19
wait..What is Apache Synapse?How is it related to WSO2 ESB? and Carbon??
20
Apache Synapse & WSO2 ESB
Leading project developed by Apache community
Most of the key committers with in WSO2 WSO2 ESB is built on top of Apache Synapse Synapse provides the core mediation
capabilities WSO2 ESB uses Synapse's configuration
language
21
WSO2 Carbon
• The Middleware framework on top of which the SOA stack is developed on
• Based on OSGi standards to achieve modularity
• Internationalized UI framework
• Shareable functional components

What if I want more? Can I extend WSO2 ESB?What if I want more? Can I extend WSO2 ESB?
Yes.. you can..Just write a mediator..
42
Extendibility
Class implementing the Mediator interface
Using Command pattern with a POJO
Scripting inside ESB
Spring initialization
43
Performance Completely asynchronous architecture internally Streaming support for messages 100% error free and zero memory leaks under heavy
load Up to 4500tps out-of-the-box for proxying
– Intel(R) Xeon(TM) 3.20GHz 2MB Cache
– Dual Core - 2 CPU system

Who can use WSO2 ESB?
47
Almost all, who knows what they want to do...
WSO2 ESB is; Simple to useEasy to learn and configure
So, any body who knowsWhat he want, can use it
Who knows the truth, lets find out our selves...
48
Sample Usage scenarios
Link legacy files to messaging based systems Transform CSV or EDI formats to XML Act as a high-performance XML Gateway Content-based routing and creating virtual
services Integrate FIX based trading systems with XML
and non-XML backends Log, trace and audit live systems
49
That's lot of information...Now I would like to try these out myself. How do I get started?
