   Automated Policy Enforcement Overview
• A service is not actually a reusable service until it
  has completed governance processes and is ready
  to meet run-time governance requirements.


                                Automation




  – The challenges of run-time SOA governance
  – Critical elements for a run-time governance framework
  – The path from automated policy enforcement to governance
                        SOA Implementation Challenges

•   Delivering on the promise of SOA
     – How to implement business process
     – How to avoid “broken” integrations

•   Maintaining Security
     – Where to enforce security
     – Ensuring end to end security

•   Ensuring Compliance
     – Instrumentation of the path and ensuring integrity
     – Providing validation and alerting mechanisms

•   Automation
     – Providing the tools to manage the system
     – Fitting into existing internal processes

 We can not support RAPID service design, delivery and change in
accordance with the governance requirements in a manual fashion.
  Service lifecycle and governance must be automated wherever
                             possible!

                                Summary
• Run-Time Governance Builds On Existing Infrastructure
   – Identity, security, provisioning, management …

• Run-Time Governance Starts With Policies
   – Must be be concise and enforceable
   – Must fit into overall business process

• Run-Time Governance Requires Enforcement and Reporting
   – Enforcement is critical first step in implementation
   – continuous reporting on compliance is important
   – Needs to be consistent and manageable

• SOA Governance Is a Goal, Not a Product
   – No single solution, but many products can help
   – Good choices can meet immediate and long-term needs
