4. SaaS – Software as a Service
What is it?
A Delivery Model
A Business Model
History
Application Service Providers (ASP’s) first
attempt at delivering software as a service in
the late 90’s resulted in failure.
First SaaS companies launched in the early
00’s

5. SaaS - Continued
Why SaaS is succeeding where early ASPs
failed?
The technology advances?
Or Economies of scale?
How to achieve the economies of scale?
Multi-tenancy
Cloud Computing
Low operating costs

6. Multi-Tenancy
Introduction
What is it?
Why we care?
What about Virtualization?
Challenges
Must be planned for since the beginning
Security
Scalability

8. What is a grid?
Cloud Computing = Grid Computing + Utility
Computing + On-demand Provisioning
Grid computing links disparate computers to
form one large infrastructure, harnessing
unused resources.
Utility computing is paying for what you use
on shared servers like you pay for a public
utility (such as electricity, gas, and so on).

9. WCF
Windows Communication Foundation
Technology part of .NET Framework 3.0 and
up to ease the development of distributed
applications
Allows to expose services using different
protocols and technologies with the same
code. (SOAP, TCP/IP, .NET Remoting,
REST ..etc)

16. PaaS - Advantages
Accelerate time to market
Reduce development and operations costs
Leverage solutions with greater functionality
and based on best practices
Simplify scalability and application
maintenance
More components can be a variable cost
instead of a capital investment or fixed cost
1616

17. PaaS - Disadvantages
Dependencies on vendors
Availability of SaaS solution depends on
availability and performance of all pieces
Lock-in
Vendors going out of business
Potentially higher cost if volume of
transactions is very high
1717

18. PaaS – Costs comparison
Majority of investment goes into
Lower total investment when
ISVs product, rather than SaaS
using a 3rd party PaaS
