25. SOA Integration in British Telecom • The B2B gateways provide the secure and reliable access channel to/from externalised services offered or consumed by the BT OSS/BSS • Each LoB OSS/BSS is makes use of a SOA based framework of reusable capabilities/SDK services based around an Enterprise Service Bus (ESB) model • Two High Availability (HA) ESB implementations exist respecting the Openreach and Rest of BT (RoBT) separation undertakings. • These two HA ESBs share a common architectural design and are based upon Oracle Fusion Middleware products – principally Service Bus (OSB) and SOA Suite

26. B2B Gateways in British Telecom • The Challenges • The common software and hardware products used for BT’s strategic gateways were fast approaching end-of-extended-support/end-of-service life • Capacity was projected to run out on some of the gateways without an uplift • The trading impact resulting from unplanned outages was not acceptable • Operating unsupported infrastructure or systems was not acceptable • Proscriptive costs to replicate or extending the then current architecture • All our strategic gateways operated from a single data centre. • Only one strategic trading gateway had DR capability • Oracle 10g B2B didn’t scale sufficiently. • Expensive non-standard architecture

27. B2B Gateways in British Telecom • Key Requirements • To address the end-of-service life risk and operational support risk • To increase operational headroom to meet projected demands • To significantly improve trading availability, ability to cope with a lose of a site and reduce down time due to upgrades and maintenance. • To significantly improve reliability, scalability and performance • To fully exploit strategic Oracle relationship and EWL entitlements • To fully exploit BT’s next generation virtual data centres and infrastructure strategy • To undertake the transition with minimal disruption to trading or customer impact • To reduce the operational carbon footprint of our systems • To comply with all equivalence of input undertakings • To minimise uplift and operational running costs

28. B2B Gateways in British Telecom Performance and Scalability • Openreach, Wholesale Retail B2B gateways are by volume the most significant. The has historically required a complex architecture underpinned by highly optimized java hardware accelerators. • Openreach Southside and Global Services Gateways have been operated using Oracle B2B 10g • Oracle** undertook to work with BT to deliver Oracle 11g suitable to run, perform, scale and operate at these enterprise levels on BTs strategic VDC infrastructure. * Peak MPS is derived from business forecast with a 50% headroom (assumed 15% of daily load in 1 hr) ** Undertaking preceded introduction of Oracle Engineered Solutions such as ExaLogic/ExaData

29. B2B Gateways in British Telecom Availability, Reliability and Operability • A dual site implementation was fundamental to maximisinggateway operational uptime and trading availability and through both planned and unplanned outages. • Multi-domain deployments at each would further increase reliability, scalability and increase operational uptime, e.g. parallel deployment. • Strategic VDC sites (Cardiff, Derby and Rochdale) are too far apart for cross site domains. Each site therefore has to operate and support full projected gateway load and throughput requirements. • Minimal disruption to CPs • Retail, Wholesale and Global Services Infrastructure Shared

30. High Availability B2B : Architectural Pattern • HA Active-Active geographical deployment • Global Site Selector (GSS) Controlled DNS Site Resolution • Riverbed Zeus/Stingray HTTP traffic management • Multi-domain Oracle 11g deployments per site • Single WLS J2EE Business Process Layer • SOA-WLS JMS queue based interconnect framework • Backend queue based integration via ESB or JBS/ESB • Veritas Cluster File System • Oracle RAC database and NLS

31. High Availability B2B : Deployment Pattern • HTTPS handshake undertaken ahead of HTTP Traffic Router in DMZ • Site Conversational ID identified or added to messages, then propagated, persisted and returned from OSS in responses • ZXTM/J2EE traffic redirection for site specific traffic. • Message handling and CP management on B2B • Action Plan, specific B2B routing and logging at BP layer • “Exactly once XA” JMS queue framework between B2B and BP layers

32. High Availability B2B : Challenges Overcome • Technical Getting Oracle 11g to scale from 30tps to well over 300tps Overcoming Latency and Bottlenecks Making Oracle 11g site agnostic • Architectural Oracle 11g B2B versus BT VDC Changes to backend BT stack to allow the gateways to operate independently Sizing the infrastructure and architecting for HA Throughput control and management • Operational CPA management Message recovery, retry and replay management Message/traffic flow control and size restrictions Service and CP deprecation, release management • Logistical Nervousness Customer testing Managing customer and service migration seamlessly and incrementally Service Deprecation

33. B2B Gateways in British Telecom : Progress • Openreach Fully transitioned from legacy platform to strategic HA Oracle 11g B2B architecture Production gateways supported from Cardiff and Rochdale VDC sites 470+ CPs migrated incrementally Transition commenced May 2012 and completed March 2013 • Retail Fully transitioned from legacy platform to strategic HA Oracle 11g B2B architecture Production gateways supported from Derby and Rochdale VDC sites Service based migration Transition commenced April 2012 and completed May 2013 . • Wholesale 99% transitioned from legacy platform to strategic HA Oracle 11g B2B architecture Production gateways supported from Derby and Rochdale VDC sites Transition commenced Jan 2013 and to be complete by November 2013

34. B2B Gateways in British Telecom : Progress • Openreach Southside First 11g B2B gateway to go live for BT Production gateway operating from single Derby UDC sites Parallel deployment with 10g gateway supporting 11g “big bang” cutover Successfully transitioned 22nd February 2012 • BT Global Services First 11g B2B gateway to go live October 2013, Trading Partner migration commence November 2013 Second site introduction February 2014 RosettaNet clients to be transitioned February 2014, completion by March 2014

35. Working with Oracle : Experience and Learning • Experience: • Essential close working relationship with the production team to better understand the product and the BT requirements and operational environment • Direct access to the development team and dedicated support engineers • Regular reviews with SOA Product and A-Teams • Regular reviews with Product Team • Dedicated Support Engineers • VikasAnand, Scott Haaland, Hugh McParland, JörgDörries, SilvieuPopescu • Learnings: • Difficulties replicating the BT problems within the Oracle test framework • Difficulties aligning the priority and inclusion of ERs/SRs within the MLR release windows • Difficulties aligning the frequency of MLRs and code releases with BT’s own release schedule and calendar of business commitments • Improving and refining the QA process and sharing tests

36. High Availability B2B : HTTP Traffic Management • Traffic Manager Software Core Load Balancing Traffic Management Session Persistence SSL services Proxy Server Script Based Configuration (Zeus Traffic Script) • BT Specific Use Load Balancing across sites and B2B domains Messages Size Restriction Service Deprecation Openreach 2 ZXTM Site 1 ZXTM Site 2 3 1 Oracle B2B Site 1 Oracle B2B Site 2 1 Outbound ebXML Request is sent via Site 1 2 CP ebXML response is sent to Site 2 by GSS 3 Zeus determines response needs to go to Site 1 based on ConversationID 4 4 Message is correctly correlated in Site 1 B2B ebXML Request ebXML Response

37. High Availability B2B : Queue Traffic Management • Openreach Openreach ESB is the sole interfacing integration layer for Openreach B2B Brokers JMS and MQ “exactly once” queue based integrations to backend components JMS load balancing, traffic control • Rest of BT (RoBT) RoBT ESB brokers only part of the systems communicating with Wholesale, Retail or GS B2B gateways JMS Broker Solution (JBS) was introduced on the consumer gateways to incrementally transition queue based between legacy and new Oracle 11g gateway sites • Pure WebLogic 11g based tactical solution • To be removed migration

38. Trading Partners Transformation and Next Steps ebXML/RNIF over https TPs to be migrated to GSS URL Still To Do • Complete Wholesale B2B migration • Complete Global Services B2B migration for ebMS and Rosettanet • Address outstanding ER/SR support for other GS protocols • Openreach reverse proxy path • Removal of the JBS • PS6 and supported roadmap • Southside physical uplift • Healthcare, Finance and Supply Chain opportunities through BT Global Services • ebMS3.0/Webservices roadmap CSM GSS ebXML/RN messages ACE CARDIFF( Legacy) ROCHDALE VDC Zeus Traffic Manager (ZXTM) StingrayTraffic Manager DUNS based routing/In-flights FTP messages Oracle B2B 10g Oracle B2B 11g In-Flight transactions WLI Email messages WLS/J2EE Broker Registry Broker Registry Traffic for other non-migrated capability Traffic for the migrated capability RoBT ESB
