Presentation OverviewPresentation Overview

1. SOA requires underlying enterprise data architecture that provides consistent, timely data

2. Data virtualization ensures data consistency for SOA

3. Data services meet performance, scalability, availability needs for SOA

4. Case studies demonstrate benefits of well thought-out data architecture for SOA

Distributed Computing CyclesDistributed Computing Cycles

SOA

Connectivity: allow any app to talk to any other app

Homogeneity: single, monolithic stack (J2EE)

Virtualization: data from any source to any user

The Optimist’s View of SOAThe Optimist’s View of SOA

Messaging Services- SOAP- XML- UDDI/LDAP

Looser coupling of commonly performed tasks

Reuse at long last through shared services

Eliminates tyranny of silos

Everything just works™

SOA Data BottlenecksSOA Data Bottlenecks

DB

PotentialData Bottlenecks

•Application level – data wait can erase grid gains

•Network level – greater flexibility can add latency

•Database level – fewer DBs may slow response

•High availability – more dependencies creates more points of failure

The Pessimist's View of SOA The Pessimist's View of SOA

Looser coupling of commonly performed tasks…

– But, tighter consistency for commonly used data Reuse at long last through shared services…

– But, lengthier development time for shared services Eliminates tyranny of silos…

– But, lose application boundaries Everything just works™…

– But, nothing ever works as advertised™

Typical Data Consistency ChallengesTypical Data Consistency Challenges

Many replicated data copies — banks have on average 43 separate counterparty databases, and 37 systems with securities data

Inconsistent data causes errors — banks attribute 45% of automated trade failures are due to inaccurate reference data

Source: Tower Group, 2003

Charlie Little

This is different stat that the 45% quoted earlier. What is the difference (so I can clarify if necessary)?

Data Integration Approaches Data Integration Approaches

Enterprise database: use existing RDBMS to access heterogeneous sources (IBM Information Integrator)

Data warehouse: real-time ETL capabilities blue lines between types of databases (Sybase IQ)

Enterprise Information Integration: new class of data servers with specialized join query (Metamatrix)

O-R Mapping tools: complements other approaches, can integrate a few (3-5) data sources (Persistence)

Data Integration AlternativesData Integration Alternatives

Technology Strengths Use if…

O-R Mapping

• Data cleansing/transformation• Complex, on-the-fly analysis

• Automates data layer development

• Ensures applications access data consistently

• Integrates with corporate standard database

• Join across multiple sources

• Need complex transformations and queries

• Building custom business apps• Need read/write data access

• Data sources are homogeneous

R-T Data Warehouse

• Meta-data management• Store any object as opaque

(serialized) structure

• Many heterogeneous data sources

• Few updates

Data Services Eliminate BottlenecksData Services Eliminate Bottlenecks

Caching EliminatesData Bottlenecks

•Application level – data cache eliminates wait

•Network level – caching reduces network traffic

•Database– caching reduces query volumes

•HA – replication ensures no single point of failure

Distributed caching eliminates bottlenecks between applications and databases

Case Study (Cont): Sell-Side Bank Business RequirementsCase Study (Cont): Sell-Side Bank Business Requirements

Project requirements

– Front & middle office equity trading: support >40 global apps– High transaction volumes: >5,000 TPS, millions per day– High availability: maximum downtime from failure <30 seconds– High scalability: support 5x volume at minimal cost– Reference data bottlenecks: all applications share common

reference & order book data = huge potential for bottleneck Deployment architecture

– Service Oriented Architecture: trading tasks exposed as shared functional services

– Persistence Data Services: Java binding, replication, caching– Grid Deployment: Unix servers (>100 CPUs), multi-site (US,

Europe, Asia), Tibco RV, MQ, Sybase

Case Study (cont): Benefits AchievedCase Study (cont): Benefits Achieved

Scalability: grid data services infrastructure scaled to $7B/day in trades (mainframe savings > $4m/yr)

Availability: stateful failover between grid data services caches helped cut failover time from 5 min to 30 sec

Productivity: SOA delivered 50% productivity through service reuse, required up-front resource (~30% of team)

Grid Data Services: distributed caching required to “grid enable” stateful SOA services to run in compute grid

NetJets ResultsNetJets Results

Best customer service in the industry – NetJets now market leader

Common Data Services layer reduced development task for each new module by 30-50%

Common Functional Services have enabled more agile development cycle = competitive gap is widening

Independent consulting firm estimated Netjets would need 15 engineers to maintain system – with SOA and MDA, they are doing maintenance with just 5 people!

ROI For SOA ROI For SOA

2x Developer productivity: after 2 years, shared services should account for > 50% of new application functionality

3x maintenance productivity: mission-critical system deployed using SOA can be maintained with 75% fewer resources

Grid deployment savings: “virtualization” of data and functional services enables distributed deployment to low cost grid computers, with 40% capital cost savings, 30% annual operating cost savings

SOA Data Architecture RoadmapSOA Data Architecture Roadmap

1. Start with data virtualization: create “golden master” data

2. Add data services: provide consistent language bindings, distributed caching

3. Migrate functionality to SOA: plan to invest 30% of dev resources into shared services

Consolidate SW

infrastructure: eliminate silos,
