SOA applications are composite applications

● An SOA application is composed from services: application components with published interface definitions

● These services require transactions to cross multiple host platforms in order to complete their functions

(5)

SOA management objectives

● Ensure service availability

– Enforce policies and mediate services

● Monitor response times

– Collect key performance metrics

● Prevent problems

– Monitor and adjust resources

● Identify and fix problems

(6)

The challenges of application management

● Business processes are built on composite applications

● Composite applications are difficult to design, build, test, and manage for high performance and availability

● Traditional management processes and tools only provide a resource-centric (silo) view of performance

SOA challenges in the SOA lifecycle

Application Deployment & Management Application

Dev. & Testing Application Design Application Developers & Testers Application Architect IT Operations Pain Points

“I now have to design a series of services instead of a monolithic application”

Incorporate security and management control points in the architecture

Understand services relationships in context of delivering functionality

Pain Points

“I now have to write a service – how do I make sure it works securely with other services I’m dependent on?”

“I have to debug why my service is not working.”

Do not have visibility to web services layer to monitor interactions

Pain Points

“I need to know when a service is not working

correctly, and be able to figure out if it’s the BPEL,

infrastructure or the application”

● Common Event Infrastructure

– IBM's implementation of a consistent approach for the creation, transmission,

persistence and distribution of a wide range of business, system and network events, based on common base events.

● Common Base Event (CBE)

– An “Event” is anything interesting that occurs from either a business or an IT perspective.

– It is the event data format IBM submitted as a standard to the

Organization for the Advancement of Structured Information Standards (OASIS).

What is a Dashboard?

● A set of components that can be grouped together to

form Business Performance Management Dashboards

– Operates in a real-time environment.

– Allows executives and business users the ability to monitor business situations.

● The dashboard components, or views, are

implemented as portlets running on WebSphere Portal

– Exploits Portal’s role based access control.

– Views are customizable and configurable to adhere to various user types.

● Leverages many different IBM technologies

– WebSphere Portal.

– DB2 Alphablox.
