Abstract:
Cloud computing offers IT resources and services as a utility, and enables a much quicker move to market at much lower cost, arguably. The initial expenses for effort and hardware are indeed lower, and potential growth is much easier handled due to the inherited elasticity. However, applications in the cloud can cause significant operational costs - different from on-premises operational costs - and hence unpleasant surprises if not architected right. Cost factors should thus become much more of a core consideration when architecting for the cloud. Different scenarios that are discussed in this paper will show how different architectural decisions result in significantly different operational costs.
