  1. Best Practices for Building an Enterprise SOA Infrastructure Antony Reynolds Craig BarrMatt Wright RamkumarMenon

  2. What We Will Do • Enterprise Deployment Guide • Explain the why • Identify best practice • Demonstrate simplified enterprise deployment

  3. Who We Are

  4. Rubicon Red • Experience • Interacted with over 100 Oracle BPM / SOA Suite customers in 6 years • Assisted in the rescue of failing projects. • Oracle Partner Network - SOA Specialization • Knowledge • Involved in first beta of Oracle SOA Suite 11g in 2007. • Co-authored ‘Oracle SOA Suite 11gR1 Developer’s Guide’ • Over 30 FMW specialist consultants – one of the largest SOA Specialized partners in ANZ • Connected • Close relationships with local and Oracle HQ based resources • Lend credibility to issue escalation • Interact with key members of product support and development team

  5. Demo Kickoff

  6. Program Agenda • Enterprise Deployment Requirements • EDG Solution • Virtualization Alternative • Automation Approach

  7. Enterprise Deployment REQUIREMENTS

  8. Enterprise Requirements - Availability • In event of server failure • No loss of service • Recovery of persistent messages • Recovery of in-flight transactions • Achieved by • Active-active configuration • Warm standby • Cold standby

  9. Enterprise Requirements - Scalability • Ability to increase capacity of system • Only scale components needing it • Achieved by • Scale out – more servers • Scale up – bigger servers

  10. Enterprise Requirements - Security • Secure servers • Prevent direct access to • App tier • DB tier • Limit services exposed • Isolate tiers • Only adjacent tiers communicate • Secure services • Authorized users only • Achieved by • Network port restrictions • Access management

  11. The Enterprise Deployment Guide • Oracle Best Practice Document • Strong on What • Weak on Why • Lacking Options • 346 Detailed Pages

  12. Networking

  13. Virtual Server Names soa.mycompany.com • What • Function specific names • Why • Separate admin from soa traffic • Separate internal from external traffic • Alternatives • Separate DNS for internal/external • OSB for all external access • 3.2 Network osb.mycompany.com admin.mycompany.com soainternal.mycompany.com

  14. Load Balancer • What • Expose virtual hosts • SSL termination • Why • IP load balancing • SSL acceleration • Port mapping • Alternatives • OTD/SLB • 3.3 Network

  15. Virtual IPs • What • Managed servers floating IP • Why • Whole server migration • Admin server failover • Alternatives • Virtualization • 3.4 Network

  16. Firewalls • What • Restrict access between layers • Why • Isolate tiers • Alternatives • May not be needed • Separate management network • Dedicated replication network • 3.6 Network

  17. File System

  18. Oracle Homes • What • At least 2 homes • Why • Separate binary from config • Resilient to corruption • Simplify patching • Alternatives • 1 local binary per server • 4.3.1 File Systems

  19. Domain Directories • What • Separate admin &managed domain dirs • Separate manageddomain dirs per server • Why • Reduce risk of corruption • Alternatives • Managed domain dirs on local storage • 4.3.2 File Systems

  20. JMS File Stores & Transaction Logs • What • Shared folder forALL servers • Why • Support recovery of JMS msgs • Support recovery of XA xacts • Alternatives • Use database for JMS queues • Use database for TLogs • 4.3.3 File Systems

  21. Database

  22. DB Requirements • What • RAC • GridLink • UTF-8 • Why • High availability & Scalability • FCF, RCLB & affinity • International character sets • Alternatives • Single instance with cold failover • 5.2 Database

  23. DB Service & Transactions • What • Optimized SOA service • Transaction privileges • Why • Load distribution & targeting • Enables XA recovery • 5.3,5.5 Database

  24. OHS

  25. OHS • What • Virtual Hosts • WL_Plugin • Why • Separate traffic • Load balancing • Alternatives • OTD • Non-Oracle web server • Same host as SOA • No OHS • 7. Web Tier

  26. Clustering

  27. Managed Servers & Clusters • What • Distributed JMS destinations • Cluster address • FrontEnd host • Why • Scalability & Resiliency • Internal service lookup • Correct redirection • Alternatives • DB store • 9. SOA, 10. BPM, 11. OSB, 12. BAM

  28. Server Migration • What • Configure node manager • Why • JMS messages recovery • XA transaction recovery • Singleton servers • Alternatives • Virtualization • DB JMS store • Cluster services

  29. Coherence • What • Use WKA discovery • List subset of servers • Why • Avoid cross talk • Only need 1 listed server • Bad Alternative • Change default multicast address

  30. Virtualization • Run managed servers in VM • VM have fixed IP • No floating IP for MS • No whole server migration • Failure of VM or VM host • Restart on available server • Live migration • Shared disk for domain/jms/tx • Maintains state

  31. Performance • Database is important • Remove OHS tier • Separate domains • Long running • Short running • SLA based • Temporal load variation • User vs System traffic • Exalogic

  32. Exalogic • New SOA EDG for Exalogic • Has options!!!! • Use OTD • Optimized with Exadata • Infiniband for internal communication • WLS & SOA optimizations • Physical or virtual

  33. Drawbacks of a Manual Approach Manual setup can be • Time consuming • Error prone Which leads to • Pain & stress • Delays in delivery • Lack of consistency • Wasted effort • How do you delivery quickly and consistently?

  34. Automation • What is available out-of-the-box?

  35. Validation Script • An automated script to check correctness • Ensures targets are defined as per EDG • Uses WLST • Target Verification Script available for download at https://blogs.oracle.com/reynolds/entry/target_verification • How do we know we built the environment correctly?

  36. Introduction Rubicon Red MyST • Declarative Configuration Management • Pre-built templates • Multi Node, Single Node, Complex, Simple topologies • No scripting or coding required • Rapid Provisioning • Define, Execute and Report on environments • Reduce effort to minutes for most complex topologies • Continuous Delivery Platform • SDLC Support for FMW Projects • Automates deployment across full set of FMW Components • Extensible Automation Framework • Supports extensions in multiple technologies • Add tasks and validators for custom components • 100% Automated Rollout of EDG Environments

  37. Extensible Pluggable Framework • Example products supported: • Oracle WebLogic Server • Oracle SOA Suite (including B2B) • Oracle BPM Suite • Oracle AIA Foundation Packs • Oracle AIA Pre-Built Integration • Oracle Service Bus • Oracle Data Integrator • Oracle Business Intelligence • Oracle Governance (OER / OSR) • Oracle WebCenter Portal & Content • Oracle Repository Creation Utility • Oracle VM • Oracle EM 12c Cloud Control • Oracle BPM Process Accelerators • Oracle Business Activity Monitoring • Oracle Business Transaction Management • Security Administration • OPatch + Smart Update • Java Connector Architecture • User Messaging Service • Oracle HTTP Server • Oracle JRockit / Sun JDK

  38. Comparing Options

  39. Back to the Demo!

  40. Benefits of Automation • Deliver significantly faster! • Deliver more reliably& consistently • Reduce overall risk • Decrease time-to-market • Delivery at the click of a button

  41. Takeaways • EDG is a Guide not a Gospel • Automation enables a different game

  42. Q&A
