We all know that SaaS stands for Software as a Service. If asked, most CIOs
would describe SaaS as Application Service Providers (ASPs) that provide hosted
applica-tions. But that's not really 'services' at all. Services are supposed
to be modular soft-ware components that provide atomic nuggets of business functionality.
But this popular definition of SaaS could change in a big way.
The fast-moving Enter-prise Web 2.0 movement, driven by SOA-like Services,
Ajax, and Mashups, could give SaaS a second life by reassigning it to SOA and
Ajax as a Service. Some might even label this SaaS 2.0. It is a trend every
IT executive should be watching.
Much of the credit for SaaS 2.0 should go to Salesforce.com. Salesforce kept
with its "No Software" value proposition throughout the tougher Web-years
and, along with its HTML-based application, began exposing actual services to
ISV partners. But, Sales-force didn't stop at exposing a few WSDLs. Why? Because
it didn't provide a way for ISVs to provide richer services. This is what Salesforce.com's
Apex development lan-guage allows. And the applications built using these resources
are offered to the public as a collection of services in AppExchange. Now that
is a meaningful set of services.
Amazon.com has its own analogs to the Salesforce.com services too. Less well-known
but equally interesting is S3, Amazon.com's virtual storage service that is
quickly being referred to as a "database in the Internet Cloud". I've
heard some execs at Amazon say that they expose these types of services because
they think corporate developers would find them as useful as Amazon does.
Both of these collections of services are pretty forward-thinking, if you ask
me. If you believe in the Long Tail, these innovators will eventually generate
far more income from third parties interacting via their services than the HTML
applications hosted on their websites. A while ago I blogged about this idea
and called it the 'Composite Company'. The idea is elegantly simple: a Composite
Company is a company built almost entirely on other company's services.
Taking this idea to the extreme, Amazon really gets it when it comes to enabling
Com-posite Companies. Beyond their basic e-commerce services, Amazon offers
the Elastic Computing Cloud ("EC3") to let developers/companies install
and run their software on as many Amazon CPUs as they need. And get this. It's
$0.10 per instance hour! Two CPUs for 24 hours is around $5. My cell phone costs
me more per day to operate. And Amazon doesn't stop there. They also have the
added benefit of accessing their infra-structure services (think storage, queuing,
etc.). Now your application services and in-frastructure services are all running
on the same practically-infinite grid.

A lot of people are talking about Enterprise 2.0 as being the business application of Web 2.0 technology. However, there's still some debate on exactly what this technology entails, how it applies to today's business models, and which components bring true value. Some use the term Enterprise 2.0 exclusively to describe the use of social networking technologies in the enterprise, while others use it to describe a web economy platform, or the technological framework behind such a platform. Still others say that Enterprise 2.0 is all of these things. Learn More
