Heterogeneous Application Landscape And The Promise Of Platform-as-a-Service

One of the most disturbing realities in the business model of an IT provider is an application landscape as heterogeneous as the world's population itself---at least it feels like that if your responsible for implementing and operating this zoo of different applications.

For a long time it seemed like a given and IT providers and datacenter organizations tried to stay abreast of the challenges resulting from this vast variety of different platforms and applications necessary for operating business processes with optimal IT support.

Quite some time ago, before the cloud hype set in, some large players as Google and its peers started to venture the land of higher level abstractions to deal with applications as first-class citizens of the datacenter. As the cloud was born, first more or less only a little more than virtualization, these players went forward and brought us PaaS.

In the more recent past the PaaS paradigm was refined by many players in the field, including the large corporations that once forced us all into lock-in with a myriad of incompatible and proprietary applications and infrastructure software.

One of the most promising projects for me in the PaaS space is Cloud Foundry (CF). Born in the realm of modern development frameworks CF has a strong focus on applications form a development and customer point of view. This is in contrast to the more operations-oriented view the earlier IaaS and PaaS offerings of the classic large ISV corporations.

Given the promise of CF and its peers we as IT service providers can look into a future of mastering a much more diversified zoo of different applications with a comparable amount of human resources.
But there is a caveat still: what is the critical mass one has to have to stay competitive in the space of cloud providers? Or is it possible to build niches where the large cloud companies do not enter?

We will see... the next few years will tell if all kind of industrial branches converge there IT into a few large cloud offerings or whether specialized providers for dedicated industries still prosper.
