3 Mastering SOA Challenges more cost-effective Service-Oriented Architecture (SOA) 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: (23-Feb-2007) Definition*:

4 Mastering SOA Challenges more cost-effective SOA – An Example Applications Business Services Legacy Assets Web Clients Mobile Devices Infrastructure Services Data Data Access Services

5 Mastering SOA Challenges more cost-effective Why SOA ? 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 Some objectives:

6 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective SOA – Challenges (a selection) Security Managing Service Metadata Interoperability Performance “Entity aggregation” SLAs Failover OLTP vs. BI/Reporting Understanding business requirements Experienced teams Service implementation and modification Load balancing Access to globally distributed services and data Service Monitoring Deployment 24x7 operation Event-Driven Architecture (asynchronous Service usage) Master data management Redundant data synchronization Legacy & Mainframe integration Platform independence Sponsorship Organization structure... Service clients for different platforms/devices

8 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective Possible solution Use DBMS that provides data replication Service

11 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective INGRES offering: Ingres DBMS OpenSource DBMS for the enterprise Robust Scalable High performance and availability Flexible backup and recovery Provides required features to master SOA challenges Uni-directional replication Distributed database support Service

14 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective Possible Solution Use middleware that provides transparent data access using a single SQL dialect SQLServer DB2 Oracle Ingres... RDB Single SQL Dialect Business Logic

16 Mastering SOA Challenges more cost-effective INGRES offering: Enterprise Access Middleware solution Single Client Interface Transparent SQL Access Transactional Web Application Support READ/WRITE Access Protects Existing Investments

17 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective INGRES offering: EDBC Middleware solution Mainframe Data Access for Distributed Applications ODBC and JDBC Drivers Metadata Mapping for Non-Relational Data Sources

20 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective Possible solution Use event-driven programming e.g. 4GL Use DBMS as event manager DBMS must support events/triggers

24 Mastering SOA Challenges more cost-effective 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 Mastering SOA Challenges more cost-effective 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
