3 SOA management challenges After completing this topic, you should be able to: Explain the challenges of managing an SOA environment

4 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 Managing SOA is part of composite application management Customer Bank Shared Service Bank 2 Supplier Outsourced

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 Trace transactions and diagnose problems

6 The challenges of application management A Composite Web Application, Involving J2EE, Integration Middleware, and Legacy Systems 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

7 SOA challenges in the SOA lifecycle Application Design Application Dev. & Testing Application Deployment & Management Application Architect Application Developers & Testers IT Operations XX Pain Points XX Pain Points XX 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 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 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 Monitor web services for problem identification Configuration and change management

8 SOA management challenge: abstraction level SOA management requires dealing with increased levels of abstraction Integration Architecture (Enterprise Service Bus) Business Process QoS, Security, Management and Monitoring Increasing Abstraction Process Choreography Services Simple and Composite Services Components Enterprise Components Legacy Application Messaging Middleware Operating System Network Managed Connectivity Tools that monitor, manage and control the services layer Tools that monitor application components, containers, and transactions Tools that monitor the health of systems Existing Enterprise Resources

16 CEI and CBE review 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). Ratified March Pub/Sub Event Distribution Event Emitter Event Source Event Consumer Event Access Event Bus Catalog and Registry Web Service Event Source Event Data Store TEC / SNMP Events Event Source

18 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. DB2 Cube Views.
