Soa meets clouds

“When SOA Meets the Clouds” A SOA perspective from trenches Edgar A Silva JBoss Brazil

In the Real World...
Events driven billions of people
Different people may react differently against some events
Examples:
Simple lights in semaphores
Raising a hand on front of some taxi
A simple smile..

So Why...
We have a complete passive model when we are designing a Service Oriented Architecture?
Many events happens into a business organization and Services can react on just one single way?

Some actual SOA drawbacks
Fault of Services Resilience
Processes are statics and depending dramatically of improvements made just by humans
Passiveness Services

Time to change...
Time to identify new patterns for a SOA 2.0 approach:
EDO- Event-driven Orchestration
ESM – Event Services Monitoring

Conceptual Foundation
CEP/ESP – Complex Event Processing
JEE6 Profile Services
OSGI
SOA 2.0 = SOA1.0+Events+Responsiveness

EDO-Event-Driven Orchestration
Actual Orchestration Techniques:
Many languages, few interaction
Our long frustration over BPEL for years
Many standards, few exchange
Why SCA when we already had JBI?
Even with all those shortcomings do you really expect that your orchestration could works fine?

Big mistakes over Processes
BPM and its big confusing on the “M”
Management
Basically an Engine
Modeling
A Designing Tool
Measurement
A Monitoring and Metrics tool
Poor reality: No options counting with everything in just one Tool/Product

Processes
Why do you need BAM ?
As one of the answer you can tell: “To answer where are the weaknesses into my processes”
How fast could you react against some weakness into your process?
a) Stop, Planning, Wait others humans interactions, Test and Deploy...
b) Measure and Deploy...

Processes X Measure
Measure
Shall be an Event
Which are fired in a time-window
According some circumstances a process can react productively, promoting changes in real-time in order to obtain a better:
a) Performance
b) Results
c) Reducing drastically time and costs for the changes

Services Orchestration based in Process
External System Action JMS Message Human Interaction Just these action on this time-line can operate the services

Services Orchestration based in Events
Events can be set of actions and can influence the process in any time and in real-time

Services Orchestration based in Events
Events Services Monitoring – A New way to see BAM
Events can be set of actions and can influence the process in any time and in real-time
