SaaS – The future of application in the cloud


SaaS? Software-as-a Service is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network typically the Internet.

How is it different from other Cloud models?
IaaS
Infrastructure as a Service is a model where service providers offer pools of abstract IT infrastructure resources (servers, storage and network components) to customers on a pay-per-usage model. The service provider owns the equipment and is responsible for housing, cooling, operation, and maintenance. The client typically pays on a per-use basic

PaaS
Platform as a Service is a model where service providers provision fully-functioning computing and solution stacks on which applications are deployed. The provider provides the networks, servers, storage for the environment, as well as manages varying levels of scalability and maintenance. The client typically pays for services used.

The history of SaaS
Utility Computing
1. Centralized hosting of business applications dates back to the 1960s. IBM and other service providers operated a service bureau business called time-sharing or utility computing.

Application service providers
2. Expansion of the Internet in the 1990’s brought about a new class of centralized computing called Application Service Providers (ASP)

Reduced costs
3. Application service providers offered businesses the service of hosting and managing specialized business applications, with the goal of reducing costs through central administration and the solution provider’s specializing in a particular business application.

Software As A Service
4. Software-as-a Service essentially extends the idea of the ASP model. The term Software-as-a Service (SaaS), however is more commonly used in specific settings.

Utilize a multi-tenant architecture
The software architecture used by most initial application service providers mandated maintaining a unique and separate instance of the application for each business. As of 2012 software-as-a service solutions normally utilize a multi-tenant architecture in which the application serves multiple businesses and users, and partitions its data accordingly.

Require only an Internet browser to use
Initial application service providers typically offered more traditional dient-server applications requiring installation of software on users’ personal computers. Contemporary Software-as-a Service relies predominantly on the web and only requires an Internet browser to use.

Develop and manage their own software
Most early application service providers focused on managing and hosting third-party independent software vendors’ software. As of 2012, Software-as-a Service vendors typically develop and manage their own software.

SaaS acronym first appears
5. The SAAS acronym allegedly first appeared in an article called “Strategic Backgrounder: Software As A Service”, internally published in February 2011 by the Software & Information Industry’s (SIIA) eBusiness Division.

Future of Cloud Computing
Analysts are seeing software as a service (SaaS) as the primary type of cloud investment with 82 percent citing usage today and 84 percent looking to SaaS as the deployment model for new applications.

Media + Entertainment
Cloud Computing has enabled media and entertainment to be a fundimentally engrained, pervasive part of our daily experience, shaping new generations of users who expect rich on-demand content delivered to a large variety of personal devices.

Social / Collaboration
The Social and Collaboration cloud formation is enabling applications that enrich supply and demand chain relationships, improve customer intimacy and loyalty, empowering collaborative, crowdsourced product design and development, drawing us closer to the markets we serve.

Mobile / Location
Today, smart phones are not only always on, but often personally upon us. Mobile devices are becoming the primary on-ramp to the cloud as people to connect to everything from their email to their business process. And as personal GPS devices, they provide continuous location data. This mobile and location cloud formation means that wherever we are, the need we have in that moment can be targeted to our location and situation.

E-commerce / Payments
The payments cloud is forming more slowly as the politics of control between merchants, banks and consumers is not easy to resolve. The Cloud, however is a key enabler as everything can be connected, validated and certified via the cloud.

Big Date / Analytics
Everything we’ve discussed generated and relies upon massive volumes of so called “Big Data” like profile and behavioral data, which needs to be stored, managed and analyzed on demand.
