Along with these, gone are any associated tools that make life easier that enabled software providers to build applications faster and cheaper by having a consolidated foundation.
Not a pleasant thought, is it?
This would mean we would be in a world of redundancy and tediousness. Each time we had to write a new application, our engineers would have to reinvent the wheel. Without an OS, engineers would write and re-write driver and hardware abstraction systems. Without application servers, web applications would be built to take care of resource management, socket cleanup, and instance management.
The reason we as a community do not live in this world is because we are lazy, and rightfully so. We enjoy having pieces of the puzzle abstracted away so we can focus on whats important. Foundational systems like the application server are the result of the natural convergence within IT to remove redundancy and improve time-to-market.
Today, software as a service (SaaS) is rapidly emerging as the next major industry shift. As expected, a new breed of foundational system is being borne with the goal of catalyzing this shift say hello to the SaaS Platform.
Building enterprise grade SaaS applications that meet the stringent requirements of business customers is difficult, to say the least. B2B SaaS applications need to embody the 365x24x7 mantra, and need to do so in a safe, performant, efficient and economical fashion.
A SaaS provider is responsible for architecting the application to meet these requirements. This means building out an appropriate infrastructure, dealing with operational headaches, ensuring security, providing flawless updates and bug fixes, as well as writing the software to be as efficient as possible to maximize tightening margins. Putting it all together, one can see that creating a B2B SaaS application adds plenty more to the already full software vendor plate. In essence, SaaS introduces a sort of SaaS Tax to the traditional software business and development equation.
Software vendors are in the business of providing value to their customers and a majority of that value is rooted in the functionality of the software. Having to detract from the core competency of delivering that functionality to deal with SaaS overhead increases time to market as well as associated operational costs. The Tax is something that all SaaS enablement concepts intend to either subsidize or repeal.
The brashest of the enablement concepts is that of the SaaS platform. A SaaS platform provides vendors with a foundation on top of which they can build their applications in a single-customer fashion, but distribute it to thousands of users at once with little effort. The vendor pays for using the platform in an on-demand fashion as well.
