Proposed Solution

Web Services

Characteristic of Web Services

Provide interoperability between various software application Standard interface on server Enable to run on disparate platformsBenefit of Web Services

Allow to share business logic, data and processes as services Reduce the software purchasing cost Form the technical foundation for software as service business model

Software As A Service

Designed from the outset up for delivery as Internet-based services Designed to run thousands of different customers on a single code Frequent, "digestible" upgrades every 3-6 months to minimize customer

disruption and enhance satisfaction.

Project Description

What is Software-as-a-Service?

Software as a Service (SaaS) is a model of software deployment where an

application is hosted as a service provided to customers across the Internet.

It is a Deployment/Delivery model Hosted andManaged by vendor Delivered across the Internet Usage-based pricing (vs. perpetual license model of on-premise software) Per user per month Per transaction Per GB of storage per month

Benefits of SaaS For Clients

Lower entry point No large up-front investment in Software licenses IT infrastructure Lower operating/maintenance costs Fast, easy deployment (Web browser) Vendor maintains/upgrades application No IT staff necessary to keep running Consumption-based expenditure Pay As You Go (OpEx vs CapEx) Scale up/down as needed

Benefits of SaaS For End-Users

Easy and rapid deployment/ramp up

Typically based on Web browser access No additional hardware/software needed Any time, Any where access Outside the corporate firewall Transparent updates 60% lower total cost of ownership over 36 months SaaS vendor manages scalability and availability, lowering infrastructure

costs for end-users

Vendor economics aligned with customer needs Easier integration & collaboration

Benefits of SaaS For Vendors

Economies of Scale Derived fromMulti-tenant architecture Better resource utilization Simplified maintenance For a well designed app, operating costs per customer drop as customer

base grows

Better understanding of usage patterns To drive innovation and enhancements Faster release cycles to keep up with market and competition De-facto access to Global market

Feasibility Study

Technical

The SAAS minimizes Technical Requirements such as System Administration,

Network Management, Data Centers, Power Management, Huge Air Conditioning

and Other Infrastructural Requirements at the Client Premises making it a

technically feasible option for the Client.

For the Service Provider, as multiple clients are sharing the same resources better

Technical Resources can be utilized.

Economical

The SAAS approach provides the most economical solution to for the Client as it

reduces the overhead costs and maintenance cost like the Infrastructural Costs

and Recurring Manpower Costs. The Subscription Fee charged by the Service

Provider are nearly at par to On-premise Software Implementation Cost and

Frequent Upgrade Costs.

For the Service Provider, the Infrastructure and Manpower Resources will be cost

effective as cost of these resources is shared among multiple clients.
