SOA in the small

– Can the service-oriented paradigm scaled down to the delivery of IT services to the consumer?

Modular deployment of service-based applications

– Servicelets for enterprises large and small

– Reaching out to small & medium businesses and emerging markets

Strategic Opportunities



State of the Art Today(What’s wrong with this picture?)

Re-use through all-Purpose Mobile Devices

State of the Art in Consumer IT

Specialized appliances enhance customer experience– Remote control devices

– Copiers, fax machines

– Confine customer into a walled garden

Device-centric view today is limiting– Devices are point devices

– Installing an application creates a hard binding between the application and the hardware– Application software vendors are not helping

– Storing a file in a PC’s hard drive creates a hard binding between the stored data and that PC’s storage device

– Forces consumer to use a specific device– Inconvenient

– Single point of failure

Computer hardware today– Standardized, interoperable

Services are not– Example: building an automobile in 1900 before Ford

7


Change is Afoot

In consumer space

– Cost of labor has not kept up with advances in technology

– IT services hardly exist

– Expensive, questionable quality, inconsistent results

– Point devices

– Customer gets unnecessarily exposed to complexity

– Digital divide

Extending the Benefits of SOA Beyond Large Enterprises

SOA adoption started with large enterprises

– Only large enterprises have critical mass to justify reuse

– Inside-out model

Outside-in model

– Extends SOA adoption model to small & medium businesses

Can we scale SOA further down?

– Bring benefits of SOA directly to consumers

Inside-out SOA eliminates duplication across stacks

…to a modular approach using SOA service modules

– Service-enable internal apps for re-use

– Remove redundancies

– Service modules generally in-sourced

(Inside-out SOA)

Economical and business considerations encourage the outsourcing of servicelets

- Demand arises for SMB specialized service providers

- Expands scope of SOA to SMBs and emerging markets

- No scaling to consumer space yet

- Best of breed solution for specialists

Servicelets and Virtual Service Oriented Grids

Servicelets

– Unit of integration/composition for SOA environments with own software and hardware

– Logically independent, self-sufficient, but not service end point

– May use Web services as integration technology

– May be built from cloud computing resources

– Composed of in-sourced or out-sourced resources

Virtual service oriented grids (VSGs)

– Servicelets built out of virtualized resources

– Servicelets in a composite application form a network or grid

– ESBs: particular instance of a VSG

The Rise of SOA Integrators

SOA providers become SOA integrators

SOA integrators build applications

– Use internal servicelets to encapsulate intellectual property (“secret sauce”)

– Rely on 3rd party servicelets for generic functions (re-use benefit)

– Applications built for resale and external consumption (value creation model)

SOA ecosystem scaling to

– Consumer space

– Emerging markets

SOA Deployment Models

Large enterprises

– Internal re-use

Small and medium businesses

– External re-use

Consumer

– Service end points of aggregated third party services

IT Services to the ConsumerWhat are IT services to the consumer?

– Data services

– Content services

– Storage services– Data presence

– Data migration, backup and recovery

– Application services

– Application installation & maintenance

– Technology services

– Network/Internet/broadband connectivity

– Help desk services– Telephone hotline and Web chat service

– Equipment installation, configuration and troubleshooting– Computer, networking & content delivery

Emerging opportunities

– Infrastructure planning

– Monitoring and security

– Integrated residential energy and resource management

– Utility, solar electric, solar thermal, wind, water management

15


Consumer Information Technology

Virtual service oriented grid perspective

Data and applications exist as independent entities– Not associated with any device

Temporary bindings for convenience of customer– Photo library not attached to single PC anymore

Compatible with legacy devices– Use desktops, laptops, UMPCs, MIDs, PDAs, cell phones as presentation

and control devices

– Presentation layer maps data to display capabilities of presentation devices

16



Service Composition in Mature Industries

SOA:

– Not a new concept

– Another name for horizontal specialization

Established pattern in mature industries

– Example: Automobile insurance industry

– Process to settle a minor accident

Insurance CompanyService Desk

SettlementCompany

Bank

Customer

RepairShop

Car rentalCompany

Single service end point

Parts suppliersAutomobiledistributor

Pay deductible expense

Provide loaner car during repairs Repair damaged vehicle

Each different color represents a different company providing

a composable service

Insurer delegates processto company with local presence

The process requires tight SLA guaranteesleading to predictable OpEx

17


Essential Ingredients for Successful Service Composition

Well-defined set of canonical services

Cost predictability

Low cost variance keeps risk in check

Fast integration ensures fast learning curve

Standardized, horizontal services

Issues in current “system”

– Current system forces consumer as point of integration

– Mixing of interface with implementation

– Function is bound to a specific hard drive

– High level of skill required

– Uncertain restoration point objective/ time objective (RPO/ RTO)

– Attaining desired SLA requires unreasonable amount of commitment

19


Backup as a Service

User stores files to protected filesystems (drive letters in Windows)– Backup to cloud storage provider during undocked work

– Local hard drive used as cache if no connectivity

– Automatic synchronization upon re-docking

SLA for backup– RPO: data loss limited to untethered work

– RTO: 24 hoursConsumer

Data Presence Service

Current issues with data

– Data is bound to a hard drive

– Data locked in islands of information

– Laptop, desktop, PDA, cell phone, distributable media, cloud, digital camera

Requirements

– Untethered data

– Available anywhere, anytime

– Presentation appropriate to device using it

– Data presence service can be coordinated with backup service

Consumer Application Architecture

VSG applications are not the same as Cloud applications

– The Cloud can be used as a mechanism to deploy a VSG application

– The application can also run as code in a client machine
