Mastering SOA Challenges more cost-effectively

This document explores the integration of Service-Oriented Architecture (SOA) and Ingres Corp's solutions to address SOA challenges effectively. It highlights the benefits of SOA, such as the reuse of services and agility in responding to business changes. Key challenges like redundant data synchronization, entity aggregation, and legacy integration are discussed, along with Ingres’ offerings for data management and service development. The focus is on creating interoperable, cost-effective services that leverage existing resources while ensuring high performance and reliability.

  1. Bodo Bergmann Senior Software Engineer Ingres Corp. Mastering SOA Challenges more cost-effectively

  2. Contents • Tell me why? • SOA • INGRES and SOA • SOA Challenges • Mastering selected challenges

  3. Service-Oriented Architecture (SOA) Definition*: • Defines the use of loosely coupled and interoperable services to support the requirements of business processes and software users. • Services can be accessed without knowledge of underlying platform implementation. • Not tied to a specific technology. • Applications (and other services) are built by combining available services.* based on definition in: www.wikipedia.org (23-Feb-2007)

  4. SOA – An Example BusinessServices InfrastructureServices Applications Data AccessServices Web Clients Data LegacyAssets MobileDevices

  5. Why SOA ? Some objectives: • Link and reuse of available resources. • Reuse of services rather than objects • Respond more quickly and cost-effectively to changing requirements. • Simplify reuse of legacy assets • application and data

  6. What has INGRES to do with SOA • INGRES offers solutions for • Data Management • Data Integration • Development and Deployment of • Services • Clients (Applications, Web, Mobile Devices) • Solutions can easily be integrated into existing SOA infrastructure • Ingres is Business OpenSource vendor • Enterprise-class solutions with minimized TCO

  7. SOA – Challenges (a selection) Master data management SLAs ServiceMonitoring Loadbalancing Interoperability Redundant data synchronization ManagingServiceMetadata 24x7operation Failover Platform independence Performance “Entity aggregation” Security Deployment Legacy & Mainframeintegration OLTP vs. BI/Reporting Access to globallydistributedservices and data Event-Driven Architecture(asynchronous Service usage) Experiencedteams Serviceimplementationand modification Service clientsfor differentplatforms/devices Understandingbusinessrequirements Organizationstructure Sponsorship ...

  8. Mastering selected challenges • Redundant data synchronization • Entity aggregation service • Unified access to different data sources • Legacy & Mainframe integration • Cost-effective service development • Event-Driven Architecture • Clients for different platforms/devices

  9. Challenge Redundant data synchronization • Services use redundant data for different reasons • Performance • Replicated services for • Load Balancing • Failover • Reduce service dependencies • ... • Redundant data have to be synchronized

  10. Possible solution • Use DBMS that provides data replication Service Service

  11. Challenge Entity aggregation service • Aggregates entities in different systems • Provides single view of entities by integrating information from different systems • e.g. combines Customer data from ERP and CRM systems • Integrates horizontal partitions • e.g. geographical separated data • Allows cross entity queries • e. g. from order management and product catalog data

  12. Possible solution • Use DBMS that provides • Replication • of horizontally partitoned data • of data from different systems • Distributed database support • Cross entity queries • e.g. in replicated data from different systems Service

  13. INGRES offering: Ingres DBMS • OpenSource DBMS for the enterprise • Robust • Scalable • High performance and availability • Flexible backup and recovery • Provides required features to masterSOA challenges • Uni-directional replication • Distributed database support Service

  14. Challenge Unified access to different data sources • Services get information from different data sources • e.g. for Data Warehousing • Service implementation should be DBMS independent • allow service to run with different DBMS • transparent data access required

  15. Possible Solution • Use middleware that provides transparent data access using a single SQL dialect Business Logic Single SQL Dialect Ingres Oracle DB2 SQLServer RDB ...

  16. INGRES offering: Enterprise Access • Middleware solution • Single Client Interface • Transparent SQL Access • Transactional Web Application Support • READ/WRITE Access • Protects Existing Investments

  17. Challenge Legacy & Mainframe integration • Mainframe information needed throughout the enterprise • Include relational and non-relational data • VSAM, IMS, CA-IDMS, CA-Datacom, DB/2 for z/OS • Transparent data access required

  18. Possible Solution • Use middleware that provides mainframe data access • From different platforms • Using standard connectivity drivers (JDBC, ODBC) • Supports SQL access non-relational data

  19. INGRES offering: EDBC • Middleware solution • Mainframe Data Access for Distributed Applications • ODBC and JDBC Drivers • Metadata Mapping for Non-Relational Data Sources

  20. Challenge Cost-effective service development • Issues: • Reduced implementation costs and time • Minimized modification time after change of business requirements • Minimize/reduce downtime for deployment of new or modified services • Flexible service deployment options • Time-to-market is important • Prevent technology and platform lock-in

  21. Possible solution • Use flexible, platform-independent high-level language (e.g. 4GL) and runtime-system for implementation of services • Implement dynamic services • Plug-in architecture • “On the fly” change options

  22. Challenge Event-Driven Architecture • Promotes loosely coupled services • Event-driven system consists of • Event consumers (subscriber) and • Event producers (publisher) • Clients and Services can be both • Client produces event to trigger service (consumer) • Service produces event to signal service finish to client (consumer) • Complements SOA • Services can be started by events (asynchronously) in addition to synchronous execution • Reduces service dependencies

  23. Possible solution • Use event-driven programming • e.g. 4GL • Use DBMS as event manager • DBMS must support events/triggers

  24. Challenge Clients for different platforms/devices • Provide service clients on a wide range of platforms without code changes • Desktop application • Web application • Mobile Client support • PDA • Mobile Phones • Rich-GUI elements should be supported • HTML is not enough

  25. Possible solution • Use platform-independent programming language (e.g. 4GL) with • Runtime system for all client platforms and devices • Platform change/add should not require rebuild • Rich-GUI-Development environment • “One for all” development environment • Different platform should not require different IDEs or languages

  26. INGRES offering: OpenROAD • Combination of • Highly productive GUI development environment and • High-performance, highly scalable middleware server • Platform independence • Clients & services binary compatible across multiple OS • Rich-GUI for web and mobile clients without code changes

  27. OpenROAD client development One Source  One Application…

  28. Deployment on different platforms One Application  Many Clients

  29. INGRES offering: OpenROAD (continued) • Powerful 4GL  High productivity • High-Level – easy to learn • Easy and quick service implementation • Less code • Combines SQL, object-oriented and event-driven programming • Allows support of SOA and EDA • Highly dynamic • “On the fly” modification of service implementation possible
