Software as a Service

Vídeo

What is SaaS?

Software as a service is a way of delivering

applications over the Internet-as a service.

Instead of installing and maintaining software,

you simply access it via the Internet, freeing

yourself from complex software and hardware

management.

Architecture

The vast majority of SaaS solutions are baseb

on a multi-tenant architecture.

With this model, a single version of the

application, with a single configuration

(hardware, network, operating system), is

used for all customers("tenants")

Architecture

To support scalability, the application is installed

on multiple machines (called horizontal scaling)

Benefits


      High Adoption

SaaS applications are available from any

computer or any device-any time, anywhere.

Because most people are familiar with using the

Internet to find what need, SaaS apps tend

to have high adoption rates, with a lower

learning curve.

Benefits

    Lower Initial Costs

Saas applications are subscrition based. No

license fees mean lower initial costs. Having the

SaaS provider manage the IT infrastructure,

and the people needed to manage it all.

Benefits

   Accelerated feature    delivery

The application is hosted centrally, so an

update is decided and esecuted by the

provider, not by customers.

The application only has a single

configuration, making development testing

faster.

Benefits

  Accelerated feature      delivery

The solution provider has access to user

behavior within the application (usually via

web analytics), marking it easier to indentify

areas worthy of improvement.

Examples

SaaS Products

First Example

Instead of selling a copy of Microsoft Word with a license, you can use the form of "renting" the word processing software for about 5 dollars a month. This way you do not have to install any software, nor you'd be confined to a single computer to use this product. Just use your web browser and log in from any computer with internet access, and likewise you can access your documents. A good example of how SaaS works this is Google Docs (with the difference that Google Docs is free).
