Future AAS

Cloud computing is in the horizon. The topic has come to architects and strategist for a consideration and discussion.  It is not in the research paper any more. It is viable to any enterprise as a technological innovative solution  for cost efficiency, speed and agility.

At this time, I should say, all the enterprise architects, strategist and IT leaders are familiar with SaaS model. Salesforce.com is a prime example of a successful SaaS model and the trust index for this business model has transformed to trust worthy due to its success.

A successful business model is always twicked and fine tuned for an another business model in a different market segment. Saas is not an exception. SaaS concept has been extropolated to other areas and there are quite a few “Aas” prolifirated so far. Here are the few..

  • Infrastructure As a Service (IaaS)
  • Platform as a Service (Paas)
  • Database as a Service (Daas)
  • STorage as a service (STaas)
  • E-mail as a Service (EaaS)
  • Desktop as a Service (DEaas)
  • ERP as a service (ERaaS)

and this list is expected to grow. IaaS and Paas sounds the same but there is a subtle difference between IaaS and PaaS. PaaS provides a platform with a set of APIs to develop applications. GoogleApp engine is a prime example of PaaS whereas Iaas provides a stack of hardware infrastructre like servers, database, network, web server, application server and etc.

Amazon is a leader in the cloud computing space. No surprise that Amazon made lots of money in the tough economy but also they projected better outlook in future. Amazon stock would become like apple or google stock.
