Preview
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


Change is Afoot
Cost of computer $10M Moore’s Law runs rampant
hardware,
It’s about to bring one more change
per delivered core 1M
100K

1960 1970 1980 1990 2000 2010

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

…to a modular approach using SOA

– Service-enable internal apps for re-use

– Remove redundancies

– Service modules generally in-sourced
(Inside-out SOA)

Inside-out SOA eliminates duplication across stacks

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

S = servicelet or microservice: self-sufficient, s/w + h/w unit composable with Web services technology


Servicelets and Virtual Service Oriented Grids
Servicelets
– Unit of integration/composition for SOA environments with own
software and hardware
An SOA composite application
– Logically independent, self-sufficient, but not service end point
– May use Web services as integration technology
– May be built from cloud computing resources S S
– Composed of in-sourced or out-sourced resources S S
Virtual service oriented grids (VSGs) S
– Servicelets built out of virtualized resources S S
– Servicelets in a composite application form a network or grid
S
– ESBs: particular instance of a VSG

The Rise of SOA Integrators

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 Consumer
What 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


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



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
Each different color Customer
represents a different Single service
company providing end point
a composable service Insurance Company
Service Desk
Insurer delegates process
Pay deductible expense to company with local presence
Bank Settlement
Company
Provide loaner car during repairs Repair damaged vehicle

Car rental Repair
The process requires tight SLA guarantees Company Shop
leading to predictable OpEx
Parts suppliers
Automobile
distributor


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


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
Consumer
– RTO: 24 hours

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
