The document discusses Eagle Technology Group's approach to migrating a client from a stovepipe enterprise system to a secure SOA enterprise. It describes properties of stovepipe systems like lack of interoperability. Eagle's method introduces web services and uses the WSO2 middleware platform to provide enterprise capabilities. Six initial WSO2 products are identified as crucial: ESB, IS, API-M, MB, G-Reg, and AS/DSS. These products help with message translation, security, proxies, deployment to environments, SSO, authorization, throttling, guaranteed messaging, and hosting services. The document outlines additional benefits of using the open source WSO2 platform.

4. Stovepipe System:
“…a pejorative term for a system that has the
potential to share data or functionality with
other systems but which does not.”
- Wikipedia
potential

5. Properties of Stovepipe Enterprise/Systems
• Primarily ‘Ad-hoc’ architectures
• Under constant maintenance, little upgrade
• Designed independently at almost every level
• Little to no interoperability – existing/known interfaces only
• Incompatible terminology, development approaches and
implementation technology
• Business centers focused on own specific business functions
instead of delivering enterprise value
• Some data model integration had started to evolve

6. Our Method to Migrate to a SOA Enterprise
• Change the software development/deployment methodology
• Proof of concept w/modern web UI dev kit (custom Bootstrap)
• Introduce web services components (SOAP & REST) for
business logic -- link to legacy with middleware
• WSO2 middleware platform to provide all of the enterprise
capabilities you want every app to have

7. Crucial Role of WSO2 Products
• Provides complete platform for ‘Trying Out’ distributed web apps
• Many products available to provide enterprise capabilities
• Agile, flexible, open to suggestions
• Keep the tech current/forward thinking—not afraid to switch out
a component technology
• Identified six initial products crucial to success for our customer:
– ESB, IS, API-M, MB, G-Reg, AS/DSS

8. Crucial Role of WSO2 Products (cont’d)
• Message translation to allow mixed technologies
• Mediation to add security information for backend services
• Centralized proxy service for common security,
authorization, and logging
• Move backend services without changing front end
• Redeploy artifacts to any environment: dev, testing, training,
staging, production, ...

9. Crucial Role of WSO2 Products (cont’d)
• Capture user info for future/modernized Federated
Systems/SSO
• Built a custom callback authenticator to use customer's
existing SSO capability

10. Crucial Role of WSO2 Products (cont’d)
• OAuth 2.0-secured service calls
• Easy role-based authorization management
• Usage throttling & monitoring

11. Crucial Role of WSO2 Products (cont’d)
• Use in any large distributed, message-based system for
guaranteed message delivery
• Used to replicate update requests/messages to multiple systems
• May replace RabbitMQ's virtual host capability (multi-tenancy
built into the WSO2 Carbon framework)

12. Crucial Role of WSO2 Products (cont’d)
• Primarily registry
• Dynamic endpoints
• Centralized security policies
• Additional artifacts to come

13. Crucial Role of WSO2 Products (cont’d)
• Hosting for Services
• Reused Existing Datasources
• Rapid prototyping of data-driven services (DSS)
• Integration at Service Host

14. Crucial Role of WSO2 Products (cont’d)
• In development
– BPS (Business Process Server)
– DAS (Data Analytics Server)

15. Crucial Role of WSO2 Products (cont’d)
• Other things we like about WSO2
– Open source using standard web/Internet technologies
– Same binary you run on the server, workstation, container, or
cloud; on Windows, Linux, etc.
– Connect Anything to Anything

16. Thank You!
