Architecture Case Studies


Client/Server -- Driven by business demands for decentralization,

flexibility and cheaper platforms.

ASP Model -- Driven by VCs’ looking to drive

more predictable revenue streams and IT vendors

looking to disintermediate traditional outsourcing

firms

SaaS Model -- Driven by buyers looking to

bypass IT backlogs, IT control, upgrade

nightmares, and to avoid long-term,

inflexible, and costly commitments

FOCUS has shifted to buyer value drivers

Early- to Mid-1990’s

Late 1990’s to 2004

2005 to 2010

…business drivers and user expectations have shifted from wanting broad applications to specialized vertical applications

SaaS Waves and the Value Curve


"The ultimate disruptive effect of the 'services wave' may well resemble that of the dot-com era, when

companies that were smart about leveraging the Web exploited unforeseen growth opportunities. As the viral growth of Web 2.0 mash-ups and walled gardens like

[salesforce.com's] AppExchange make clear, every true SaaS application is potentially part of an XML-driven

ecosystem. The SMBs that figure out how to tap into the power of those ecosystems could become the

enterprises of tomorrow." - Eric Knorr

InfoWorld : March 2006


Characteristics of SaaS – A Definition

Central management of services – The SaaS applications are hosted, managed, and maintained in a centralized data center offering access to its applications/services via the Internet and a Web-based interface.

Application Accessibility – Policy-driven configuration and personalized customization, giving users the ability to have control over how the application is used, rather than how it is implemented.

A one-to-many service- In order to accomplish the “economies of scale”– SaaS requires a multi-tenant application that supports multiple end-users accessing a single source of the application business logic and database.

Guaranteed performance and reliability via service level agreements - delivery of contracted services with a guarantee that certain metrics are met. (accessibility, reliability, and overall throughput or performance)

Application Requirements


Agenda




Case Study- Multi-tenancy/security- KCS

GOALS:• Provide customers with comprehensive HR/ Payroll applications

– Multiple market segments• Assume the day-to-day management responsibility

– provide improved control of the data and application/management reports• Overcome the concern about data security, stability and reliability

HOW:• Security control system - database update, enquiry, at field/user level

– Access and update controls established by user, department, cost centre, office, company or total database; or by employee type, grade, or position

• Self-service Portal –allows employees to update information for themselves, manage and query their own data

• 'Sets' facility which allows for creation of employee records for individual tasks

• Input data directly -allowing anytime, anywhere input from one source, regional or line management

• Integrated modular solution – the core personnel administration database can be accessed by a

number of optional bolt-on components


Case Study- Multi-tenancy/security- KCS

RESULTS:• Chose a hosting partner where the infrastructure they

operate with is completely secure - uses biometric technology for access and the building is as inherently secure as the data.

• Leverage a multi-tenanted system for hosting multiple end user customers that all log into the same ISP.

• Foster a high degree of confidence through growth - achieving a 10% increase in annual revenue

• Offer a full menu of options and supply both sides of the process - providing whatever range of technology services are required and help adapt to business changes.


Case Study – Personalization- ePropertyTax

GOALS:

• To be both a software technology and a property tax service company

• Design a service plan for each customer around needs and requirements

• Continuously provide updates and maintain valuable property tax content, without customer involvement

• Create a shared resources environment more powerful and scalable than any single customer configuration.

• Allow customers to own their own data, and remove it at anytime. HOW:

• Architected a hosted solution with a focus on Customer personalization using Web Speed

• Handle scalability and volume using 6 Brokers and 2 app servers

• Update product features weekly and apply tax changes yearly to single code base

• Provide user permissions at a function level – with field level security - all data logically segregated by company ID – set up Queries with Company ID


Case Study – Personalization - ePropertyTax

RESULTS:• Property Tax Office® is an open platform that allows

customers to choose anyone to service their property taxes. • A fully Web-native software application, delivered through the

Internet, with the best cost/benefit relationship in the marketplace

• Designed and implemented the first automated and digitally monitored quality control process for property tax compliance.

• Give customers real-time visibility of the status of every tax bill, assessment, and personal property tax return that we are processing, providing constant assurance of on-time quality service

• Pricing – per property managed


Case Study – Full-Service– FARA Business Systems

GOALS: • To provide insurance/risk management related services to insurance

companies• Increase revenue per associate -utilizing the latest cost effective

technologies• Perform application management, support, backup/restore, and Disaster

Recovery• Ability to keep cost and disruption very LOW…with accessibility very HIGH

HOW:• Develop a single code set with a single common database with segmentation

at the company level• Provide access via a web browser – not “n-tiered”• Added value comes in the form of additional IT support for app mgmt,

backup/restore with a focus on DR.• Little customization – more focus on the “like” business processes• Creating new products- based off of the “core” product –new users


Case Study –Full Service- FARA Business Systems

RESULTS:• 24x7x365 claim reporting system with immediate claim

confirmation and assignment

• Web access to claim progress notes, reserves, payments, digital images, etc.

• Business intelligence to manage each claim to a low-cost, high satisfaction result.

• Application delivered as a service is up and running in 60 days or less

• Provides quarterly new features with weekly updates/fixes – performs pre-test and have rollback capabilities

• Meets all security needs – has knowledge of what is needed in the industry and provides for it….


In Summary

SaaS is disrupting the industry, offering large opportunity/potential

Design and Architect your applications with SaaS built in
