Introducing Mattson ...
Hi..
Mattson here..
Heard about a webinar
from WSO2 I am an
On making it easy to do Enterprise architect
Enterprise Integration
Have a few Questions
though :-(

What is
Enterprise Integration?
4

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
5

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
6

Well, I heard about ESB
Before
But not so clear about it
So What is
ESB?
Hey Mattson, it is
“Enterprise Service Bus”
7

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 :-)

When do you need
an ESB?

18

wait..
What is Apache Synapse?
How is it related to
WSO2 ESB? and Carbon??
19

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
20

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
21

What if I want more?
Can I extend WSO2 ESB?
Yes.. you can..
Just write a mediator..
41

Extendibility
Class implementing the Mediator interface
Using Command pattern with a POJO
Scripting inside ESB
Spring initialization
42

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
– 2GB RAM
– 1Gb Ethernet

Non-Blocking IO
Synapse

This model means:
1. Synapse threads never blocked during normal processing
2. Number of sockets open >> number of threads
45

Who can use
WSO2 ESB?
